三角共路型干涉成像光谱仪图像模拟技术研究的中期报告【摘要】三角共路型干涉成像光谱仪是一种新型的光谱仪器，它能够在一张图像中获取物体在不同波长下的光谱信息，具有高光谱分辨率、快速成像等优点。但是，由于其工作原理较为复杂，传统的光学设计方法难以完全满足其需求，因此需要采用图像模拟技术来解决设计问题。本文介绍了三角共路型干涉成像光谱仪的工作原理，并提出了一种基于偏振光传输矩阵的图像模拟方法。通过模拟实验验证，该方法能够准确地预测仪器的成像效果和光谱分辨率，并且具有较高的计算效率。【关键词】三角共路型干涉成像光谱仪；偏振光传输矩阵；图像模拟【Abstract】Thetriangulation-basedinterferometricimagingspectrometerisanovelspectralinstrumentthatcanobtainspectralinformationofanobjectatdifferentwavelengthsinasingleimage.Ithastheadvantagesofhighspectralresolutionandfastimaging.However,duetoitscomplexworkingprinciple,traditionalopticaldesignmethodsaredifficulttomeetitsdemands.Therefore,imagesimulationtechniquesareneededtosolvethedesignproblemsofthisinstrument.Thispaperintroducestheworkingprincipleofthetriangulation-basedinterferometricimagingspectrometerandproposesanimagesimulationmethodbasedonthepolarizationtransfermatrix.Throughsimulationexperiments,itisverifiedthatthismethodcanaccuratelypredicttheimagingperformanceandspectralresolutionoftheinstrument,andhasahighcomputationalefficiency.【Keywords】Triangulation-basedinterferometricimagingspectrometer;polarizationtransfermatrix;imagesimulation
