Reflection Spectrum(反射光谱)研究综述
Reflection Spectrum 反射光谱 - This design can effectively avoid the pasting process of the grating area and the concomitant problem of chirp phenomenon in the reflection spectrum and promises a high sensitivity and resolution. [1] Three clear resonances were observed in the reflection spectrum, which were corresponding to the fundamental mode (LP01), the first-order mode (LP11), and the coupling mode (LP01–11). [2] The absorption in amorphous silicon nano antennas is engineered for the purpose of post process structural change via resonant laser printing by illumination, thus shifting transmission and reflection spectrum in a controlled manner. [3] When the output energy of KrF exciter laser is 400 mJ and the frequency is 25 Hz, the reflection spectrum and transmission spectrum of the double clad fiber grating obtained from the experiment indicate that the most important factor affecting the central reflection wavelength and power of the fiber grating is the environment and the stress on the axis of the grating. [4] The thermal stability, UV/Vis diffuse-reflection spectrum and photocatalytic behavior of 1 against organic dyes have been investigated. [5] The reflection spectrums of the FBGs in the mixed substrate are measured, and the effect of the horizontal position and embedded depth of the FBG is analyzed experimentally. [6] The physical mechanism of the polarizer is analyzed through the reflection spectrum, the electric field distribution, the energy flow, and the power dissipation density calculated by transfer-matrix method and finite-difference time-domain method. [7] By partly inserting an ECFBG into a ceramic ferrule, the reflection spectrum of the ECFBG splits into two peaks as a result of the applied tilt angle. [8] Theoretical and experimental results show that our scheme significantly improves the spatial resolution performance of the reflection spectrum of dynamic grating. [9] Analyzing the unpredictable effect from properties of multi‐layered structure on the reflection spectrum. [10] The reflectivity is nearly zero at the valley of the reflection spectrum because of the strong coupling between LSP and PSP. [11] To probe the shift, we effectively set one end of the transmission line as a mirror, and examine the reflection spectrum of the probe field from the other end. [12] The UV absorption, transmittance, reflection spectrum and optical constant computed of the prepared samples. [13] Using multiple physical field numerical module of the finite element method, the reflection spectrum with two relatively independent peaks is formed. [14] Two well-defined wavelength bands are observed in the reflection spectrum of the proposed sensor, i. [15] The analysis of optical properties, including the calculation of dielectric function, reflection spectrum and absorption spectrum of Fe/Co–doped BaTiO3 system, implied that their photoelectric properties can be improved by Fe/Co–doping due to the required activation energy for the photoelectron transition being reduced effectively. [16] Sensor signals are designed and simulated by solving coupled mode equations using the transfer matrix to represent the reflection spectrum of π-PSFBG. [17] The reflection intensity of sensor can be measured by smartphone and the surrounding refractive index is monitored by the shift of the reflection spectrum. [18] A newly synthesized, single-step silicone acrylate formulation cured by conventional radiation produced a reflection spectrum that showed an unusual interference pattern for a single-step coating. [19] The velocity can be measured by monitoring the reflection spectrum. [20] When the temperature or strain applied to a particular random grating is changed, the central wavelength of the reflection spectrum of the random grating will change, which is converted to the time domain as a time shift based on SS-WTT using a linearly chirped fiber Bragg grating. [21] A co-propagating broadband light signal (also in the near-infrared region) is used to measure the reflection spectrum of the grating and thus the temperature from the wavelength shifts of the reflection peaks. [22] In this study, the variation degree and range of reflection spectrum was quantitatively measured for both healthy leaves and disease spots in cucumber plants. [23] That is to say, the reflection spectrum of visible light (380-780 nm) is measured at 5-nm intervals on the surface of leaves or petals in 'Spectrometric Color Measurement' (SCM). [24] The 1D PC consisting of dielectric multilayer stacks with alternating refractive indices forms a PBG in the reflection spectrum. [25] Because the reflection spectrum of the sensor is formed by the fiber cavity, air cavity and their combined cavity, which can be processed by methods of fast Fourier transform (FFT) and Fourier band-pass filter (FBPF), so we can analyze the corresponding responses of every cavity from the reflection spectrum of sensor for temperature and pressure variations. [26] The reflection spectrum is shaped into a broad rectangular flat-bottom feature by placing the ultra-thin absorber at the antinode of standing wave mode of dielectric layer. [27] The structure models of reflection-type one-dimensional magnetophotonic crystals are designed, the magnetic field direction control characteristics of reflection spectrum and Kerr rotation angle are discussed, and the effect of applied magnetic field direction and strength on reflection spectrum and Kerr rotation angle are analyzed. [28]这种设计可以有效地避免光栅区域的粘贴过程以及随之而来的反射光谱中啁啾现象的问题,并保证了较高的灵敏度和分辨率。 [1] 在反射光谱中观察到三个清晰的共振,分别对应于基模(LP01)、一阶模(LP11)和耦合模(LP01-11)。 [2] 非晶硅纳米天线中的吸收被设计用于通过照明的共振激光打印来改变后处理结构,从而以受控方式改变透射和反射光谱。 [3] 当KrF激发激光器的输出能量为400 mJ,频率为25 Hz时,实验得到的双包层光纤光栅的反射光谱和透射光谱表明,影响光纤中心反射波长和功率的最重要因素光栅是环境和光栅轴上的应力。 [4] 研究了1对有机染料的热稳定性、UV/Vis漫反射光谱和光催化行为。 [5] 测量了混合基板中FBG的反射光谱,并通过实验分析了FBG水平位置和嵌入深度的影响。 [6] 通过传输矩阵法和有限差分时域法计算出的反射光谱、电场分布、能量流和功率耗散密度,分析了偏振片的物理机理。 [7] 通过将 ECFBG 部分插入陶瓷插芯中,ECFBG 的反射光谱由于施加的倾斜角而分成两个峰。 [8] 理论和实验结果表明,我们的方案显着提高了动态光栅反射光谱的空间分辨率性能。 [9] 分析多层结构特性对反射光谱的不可预测影响。 [10] 由于 LSP 和 PSP 之间的强耦合,反射率在反射光谱的谷底几乎为零。 [11] 为了探测这种偏移,我们有效地将传输线的一端设置为镜子,并从另一端检查探测场的反射光谱。 [12] 计算制备样品的紫外吸收、透射率、反射光谱和光学常数。 [13] 利用有限元法的多物理场数值模块,形成具有两个相对独立峰的反射光谱。 [14] 在所提出的传感器的反射光谱中观察到两个明确定义的波长带,即。 [15] 光学性质分析,包括对 Fe/Co 掺杂 BaTiO3 体系的介电函数、反射光谱和吸收光谱的计算,表明 Fe/Co 掺杂可以提高其光电性能,因为它需要光电子的活化能。过渡有效减少。 [16] 传感器信号的设计和仿真是通过使用传递矩阵求解耦合模式方程来表示 π-PSFBG 的反射光谱。 [17] 传感器的反射强度可以通过智能手机测量,并通过反射光谱的变化监测周围的折射率。 [18] 一种通过传统辐射固化的新合成的单步有机硅丙烯酸酯配方产生的反射光谱显示出单步涂层不寻常的干涉图案。 [19] 可以通过监测反射光谱来测量速度。 [20] 当施加在特定随机光栅上的温度或应变发生变化时,随机光栅的反射光谱的中心波长将发生变化,该中心波长将转换为基于 SS-WTT 使用线性啁啾光纤布拉格的时间偏移的时域光栅。 [21] 共同传播的宽带光信号(也在近红外区域)用于测量光栅的反射光谱,从而测量反射峰波长偏移的温度。 [22] 本研究定量测量了黄瓜植株健康叶片和病斑的反射光谱变化程度和范围。 [23] 也就是说,可见光的反射光谱(380-780 nm)是在“光谱颜色测量”(SCM)中以5-nm的间隔在叶子或花瓣表面测量的。 [24] 由具有交替折射率的电介质多层堆叠组成的 1D PC 在反射光谱中形成 PBG。 [25] 由于传感器的反射光谱是由光纤腔、空气腔及其组合腔形成的,可以通过快速傅里叶变换(FFT)和傅里叶带通滤波器(FBPF)的方法进行处理,因此我们可以分析对应的传感器反射光谱中每个腔体对温度和压力变化的响应。 [26] 通过将超薄吸收体放置在介质层驻波模式的波腹处,反射光谱被塑造成一个宽的矩形平底特征。 [27] 设计了反射型一维磁光子晶体的结构模型,讨论了反射光谱和克尔旋转角的磁场方向控制特性,分析了外加磁场方向和强度对反射光谱和克尔旋转角的影响。 .

The adsorption mechanism was explored by means of the IR spectrum and the UV-vis diffuse reflection spectrum (DRS) together with theoretical calculations. [1] Scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), Brunauer–Emmett–Teller (BET) surface area analyses, and UV–vis-diffuse reflection spectrum (UV–vis-DRS) and photoluminescence spectrum (PL) data were used to characterize the TPGBM. [2] Through UV diffuse reflection spectrum, the band gap of HU11 with 3. [3] Combining with diffuse reflection spectrum and valence band X-ray photoelectron spectrum, the calculated conduction band value of the P-BiVO4 is about 0. [4] X-ray diffractions (XRD), scanning electron microscope (SEM), and ultraviolet-visible diffuse reflection spectrum (UV-vis) analytic methods were used to characterize phases , microstructure and visible-light response properties of samples in order to understand the influence of pH value. [5] Optical characterizations contain single crystal X-Ray diffraction (XRD), powder XRD, Raman spectrum, UV-vis-NIR diffuse reflection spectrum, and SHG responses measurement at 2. [6] The determination is based on the measuring hypsochromic shift of a short-wave surface plasmon resonance band in a diffuse reflection spectrum of the nanocomposite. [7] The morphology, crystalline structure, diffuse reflection spectrum and element chemical status of the products were characterized using scanning electron microscopy (SEM), X-ray diffractometer (XRD), ultraviolet visible spectrophotometry (UV–Vis DRS) and X-ray photoelectron spectroscopy (XPS), respectively.

Fbg Reflection Spectrum Fbg 反射光谱
As a spectral improvement purpose, the Gaussian apodization function is applied on FBG reflection spectrum to optimize spectra by supressing side lobes. [1] For the fiber Bragg grating (FBG) sensor based on the reflection peak position searching demodulation algorithms, a key problem is that the demodulation precision of measurement signal is seriously limited by the full width half maximum (FWHM) of the FBG reflection spectrum. [2] The dynamic interaction model for PON-LHDS with a 2-D optical encoder supporting 2m−1 users is derived by discussing the overlap between the failure-detecting light pulse spectrum and the FBG reflection spectrum, where m is the number of the failure-detecting light sources. [3] The proposed sensor is based on the influence of each displacement condition, namely, axial strain, torsion, and bending on the FBG reflection spectrum. [4] Our method is based on calculating the maximum oscillation frequency of the side-lobes of the FBG reflection spectrum. [5] In this paper, we propose a fast-self-adaptive multi-peak seeking algorithm to detect the central wavelength shifting of the FBG reflection spectrum with the crack propagation. [6] A method to segment multi-peak FBG reflection spectrum based on continuous wavelet transformation (CWT) is proposed and experimentally demonstrated. [7]作为光谱改进的目的,高斯变迹函数应用于FBG反射光谱,通过抑制旁瓣来优化光谱。 [1] 对于基于反射峰位搜索解调算法的光纤布拉格光栅(FBG)传感器,一个关键问题是测量信号的解调精度受到FBG反射光谱半峰全宽(FWHM)的严重限制。 [2] nan [3] nan [4] nan [5] nan [6] nan [7]
Andreev Reflection Spectrum Andreev 反射光谱
We believe that this work is helpful for ascertaining the signature of MZM in the Andreev reflection spectrum. [1] Detailed analysis finds that the larger gap possesses an $s$-wave nature, but the smaller gap exhibits a sharp peak feature near zero energy on the Andreev reflection spectrum manifesting a possible nodal gap. [2]我们相信这项工作有助于确定 MZM 在 Andreev 反射光谱中的特征。 [1] 详细分析发现,较大的间隙具有$s$波性质,但较小的间隙在Andreev反射光谱上表现出接近零能量的尖峰特征,表明可能存在节点间隙。 [2]
Polarized Reflection Spectrum 偏振反射光谱
Owing to the birefringence, a cross-polarized reflection spectrum displays two sharp peaks from each component that decreases the monochromaticity. [1] The results show that The THz PMMs biosensor cannot distinguish cell concentrations within the orders of magnitude between 1 × 104 and 5 × 104 cells/ml, however, it can distinguish cell concentrations within the orders of magnitude between 1 × 104 and 1 × 105 cells/ml based on the x-polarized reflection spectrum TPMMs biosensor. [2]由于双折射,交叉偏振反射光谱显示来自每个分量的两个尖峰,这降低了单色性。 [1] 结果表明,太赫兹 PMMs 生物传感器无法区分 1×104 和 5×104 个细胞/ml 数量级内的细胞浓度,但可以区分 1×104 和 1×105 个细胞数量级内的细胞浓度。 /ml 基于 x 偏振反射光谱 TPMMs 生物传感器。 [2]
Whose Reflection Spectrum 谁的反射光谱
By comparing the colours of the experimental sample and the corresponding structure, whose reflection spectrum was calculated, the thicknesses of bulk MoS2 layers were determined preliminarily, which laid the foundation for the accurate measurement of the thickness, subsequently, through methods based on atomic force microscopy, Raman spectroscopy, and other linear and nonlinear optical processes. [1] In this design, the solution sample is introduced into the ROTE resonant cavity, whose reflection spectrum presents a large shift of its resonant dip in response to the tiny change of the solution RI. [2]通过对比实验样品和相应结构的颜色,计算其反射光谱,初步确定了块状MoS2层的厚度,为厚度的准确测量奠定了基础,随后通过基于原子力显微镜的方法、拉曼光谱和其他线性和非线性光学过程。 [1] 在该设计中,溶液样品被引入 ROTE 谐振腔,其反射光谱响应于溶液 RI 的微小变化而呈现出其谐振倾角的较大偏移。 [2]
reflection spectrum shift 反射光谱偏移
The analysis of the original sensor model shows that the resonance wavelength of the proposed grating's reflection spectrum shifts to the long-wave direction with the change of refractive index. [1] When the sensing head is exposed to a hydrogen environment, heat is generated due to the interaction between hydrogen and ${{\rm WO}_3}$WO3 with the help of catalyst Pt in air; then, the local temperature of the PMF increases, which results in the reflection spectrum shift because the light polarization state changes due to the variation of the birefringence coefficient of the PMF. [2]对原始传感器模型的分析表明,所提出的光栅反射光谱的共振波长随着折射率的变化而向长波方向偏移。 [1] 当传感头暴露在氢气环境中时,由于氢气与${{\rm WO}_3}$WO3在空气中催化剂Pt的帮助下相互作用而产生热量;然后,PMF的局部温度升高,这导致反射光谱偏移,因为PMF的双折射系数的变化导致光的偏振态发生变化。 [2]
