摘要

基于AOTF的成像光谱仪是集图像、光谱及偏振信息为一体的新型探测仪器,由于声光晶体是其核心分光器件,它的性能将影响目标信息的获取能力。因此,研究提高声光晶体衍射效率的方法是AOTF成像光谱仪研制的重点和关键。首先介绍了AOTF成像光谱仪的工作原理,基于耦合波理论推导了声光晶体衍射效率方程,然后对AOTF成像光谱仪声光晶体衍射效率的影响因素进行数值仿真分析,最后,用Tracepro软件对不同入射光进行了仿真计算。分析结果表明,当AOTF成像光谱仪工作波长范围在0.4 μm~0.9 μm时,为使衍射效率能达到最大值,各个影响因素的最优值是:换能器长度d为2.5 mm,光栅倾斜角φ选择在80°,入射光选择o光。

Abstract

The imaging spectrometer based on acoustic-optic tunable filter (AOTF) is a new detector which integrates image, spectrum and polarization information. Because the acousto-optical crystal is the core optical splitter, its performance can affect the acquisition ability of the target information. Therefore, the key point of AOTF imaging spectrometer development is to study the method for improving the diffraction efficiency of acousto-optical crystal. Firstly we introduced the working principle of AOTF imaging spectrometer, derived the acousto-optical crystal diffraction efficiency equation based on coupled wave theory , then analyzed the influencing factors of the AOTF imaging spectrometer on acousto-optical diffraction efficiency by numerical simulation. Finally,through using TracePro software, we simulated and calculated different incident light . The analysis results show that when the AOTF imaging spectrometer works at the wavelength range of 0.4 μm~0.9 μm,in order to make the diffraction efficiency reach the maximum value and the various influence factors reach the optimal values, the transducer length is d=2.5 mm, the tilt angle of grating selects 80 °and the incident light selects o light.
