成像光谱仪一体化设计

The Integrative Design for Imaging Spectrometer

随着超光谱成像技术的发展,超光谱成像光谱仪的要求也随之提高,小型化、高光谱分辨率和高空间分辨率成为发展趋势,这就要求设计者在进行仪器设计的过程中不断完善和优化设计。提出了成像光谱仪一体化设计的方法,即不单纯地进行光谱仪分光系统的设计,而是将光谱仪分光系统置于整体结构中进行整体系统设计和优化,从而实现超光谱成像光谱仪的最佳设计结果,并以近年来应用较为广泛的凸面光栅成像光谱仪为例,较为详细地阐述了成像光谱仪一体化设计方法在系统研制过程中的应用,并通过对该凸面光栅成像光谱仪的测试验证了该方法的正确性。

The hyperspectrum imaging spectrometer will achieve miniaturization and high spectrum resolution and high space resolution along with development of the hyperspectrum imaging technology that is becoming a trend.This trend requires the designers to improve and optimize their designing constantly in designing the instruments.The present paper carried out a method of integrative design for imaging spectrometer.This method suggested that the design and optimization work of the disperse systems of imaging spectrometers would take into account the whole systems,but not consider themselves only.It would get a perfect result by using this method.This paper also explained in details how the method can be used in the design course of imaging spectrometer with convex grating which has been used widely recently.Finally,this paper validated the method by testing the imaging spectrometer with convex grating,which was developed using this method.
