Zemax基于双光栅干涉的高光谱成像方法研究

摘要在干涉成像光路中加入色散元件光栅是一种创新性的干涉成像光谱技术。不仅继承了传统干涉成像光谱技术固有的高通量、多通道等优点，同时可以兼备利用光栅超分辨光谱能力。本论文重点围绕基于双光栅干涉的高光谱成像技术展开研究。以干涉成像光谱技术理论为基础，研究了基于双光栅干涉的成像光路模型，提出了两种光路方案，分析了它们的基本结构和工作原理。简单论述了光谱复原算法与步骤。使用Matlab、Zemax软件对基于双光栅干涉的高光谱成像技术进行了原理和系统仿真。仿真验证表明，基于双光栅干涉的高光谱成像技术除了具有干涉成像光谱技术的基本优点外，具有高光谱分辨率的优点，干涉图的最大和最小光谱频率都可以被调到和探测器光谱灵敏度相匹配或所感兴趣的光谱区域，能够在不影响空间分辨率的前提下有效地提高光谱分辨率。

Title Hyperspectral imaging based on double gratings interferometer
Abstract
Putting dispersive element gratings into interferometer is an innovative interferometric imaging spectroscopy. The technology inherits the inherent advantages of the Fourier transform spectroscopy such as high-throughput，multi-channel, etc.and can also involved in the super-resolution.What this paper focuses on is hyperspectral imaging technology based on double gratings interferometer.Based on the theory of interferometric imaging spectrometer, we study the imaging optical model based on the double gratings interferometer, propose two optical solutions and analyze their basic structure and operating principle.Then we will discuss the spectral recovery algorithm and steps simply.Using Matlab, Zemax software, we simulate the system of hyperspectral imaging technology.Simulation results show that the hyperspectral imaging technology based on double gratings interferometer has the advantage of high spectral resolution in addition to the basical advantages of Fourier transform spectroscopy.Maximum and minimum spectrum frequency of interference pattern can be transferred to the spectral region which matches the spectral sensitivity of the detector.So we can improve spectral resolution without destruction of spatial resolution.
