标题： Design Simulation of Czerny-Turner Configuration-based Raman Spectrometer using physical optics propagation algorithm

摘要： 我们报告使用光学系统设计软件Zemax进行拉曼光谱仪的设计仿真。 该设计基于Czerny-Turner结构，包括由入射狭缝、两个凹面镜、反射式衍射光栅和图像探测器组成的光学系统。 通过引入探测器像素与波长、线性CCD接收表面长度和图像表面尺寸之间的对应关系，提出了系统的建模方法。 已使用POP（物理光学传播）算法进行了仿真。 对拉曼光谱仪进行了点列图、相对照度、辐照度图、调制传递函数（MTF）、几何和包围能量的仿真。 给出了使用527 nm波长激光作为激发光源的拉曼光谱仪的仿真结果。 目前的光学系统在顺序模式下设计，并观察到530至630 nm范围内的拉曼光谱。 分析表明，系统的成像效率较高，预测可以构建一个高效且成本效益高的拉曼光谱仪用于光学诊断。 显示英文摘要

摘要： We report the design simulation of the Raman spectrometer using optical system design software Zemax. The design is based on the Czerny-turner configuration which includes an optical system consisting of an entrance slit, two concave mirrors, reflecting type diffraction grating, and an image detector. The system's modelling approach is suggested by introducing the corresponding relationship between detector pixels and wavelength, linear CCD receiving surface length, and image surface dimension. Simulations have been carried out using the POP (Physical Optics Propagation) algorithm. Spot diagram, relative illumination, irradiance plot, Modulation Transfer Function (MTF), geometric, and encircled energy simulated for designing the Raman spectrometer. The simulation results of the Raman spectrometer's using a 527 nm wavelength laser as an excitation light source are presented. The present optical system is designed in sequential mode and a Raman spectrum observed in the range of 530 to 630 nm. The analysis shows that the system's image efficiency is higher, predicting that it is possible to build an efficient and cost-effective Raman spectrometer for optical diagnostics.
