摘要

摘要: 基于AOTF成像光谱仪原理样机的总体设计方案，提出工作谱段范围400nm～900nm声光可调谐滤波器(AOTF)成像光谱仪系统的光机系统设计。该原理样机的光学系统采用三组镜头组合而成，前置望远镜系统采用1倍的物镜与准直镜光学系统组合，成像镜同时采集由AOTF产生的正交偏振的正、负一级衍射图像，全系统在32lp/mm的空间频率下，MTF大于0.7。

Abstract: Based on the system design cooncept of acousto-optic tunable filter(AOTF) imaging spectrometer, optomechanical design for an acousto-optic tunable filter(AOTF) imaging spectrometer was presented. It consisted of three group optic lenses. The fore-optical system included objective and collimating lens and the imaging lens collected the +1 and -1 orthogonally polarized orders produced by the AOTF at the same time. The whole system is achromatized from 0.4～0.9 microns and imaging resolution is better than 32lp/mm when MTF reach 0.7.
