Title Research On The Hyperspcetral Imager Using Symmetric Wedge Interferometric Cavity
Abstract
Interference imaging spectroscopy has developed rapidly in recent years, in the remote sensing detection and agricultural production and other fields has been widely used. The imaging principle, basic structure and features of the interference imaging spectrometer are analyzed. The optical model of the hyperspectral imager based on the symmetric and cuneal cavity is studied. The working principle and basic structure of the instrument are discussed. Simulate the optical model by the ZEMAX software and discuss the system parameters. On this basis, discussed the relationship between the interference information and spectral information of the multiple beam interference. The algorithm of recovering the spectrum is studied by the MATLAB software. Experimental device is set up to carry out experiments and the results are analysed. The good performance of the system with huge throughput, high spectral resolution and high target resolution. The optical model of the hyperspectral imager based on the symmetric and cuneal cavity presents a new method for hyperspectral imaging.

干涉成像光谱技术是利用干涉信息与光谱信息之间的对应关系，将二者有机的结合在一起。在对探测目标进行成像基础上，对离散的干涉信息进行复原变换，同时得到探测目标的二文图像信息和一文光谱信息，从而获取探测目标的数据立方体。它具有高光谱分辨率，高光通量等优点，在航空、航天、遥感、资源勘探、环境监测等领域得到广泛的应用。干涉成像光谱技术中利用不同的分光方法和调制方法可以构成不同的干涉成像光谱仪系统。其中相面干涉成像光谱仪系统是一种前沿的光谱成像技术，与传统的空间调制型干涉成像光谱仪相比，它摆脱了狭缝的限制，具有高光通量、高光谱分辨率和高目标分辨率等优点，在军用和民用领域具有广阔的应用前景。
