摘　　要：利用TracePro光学软件对不同焦距的球面反射镜和抛物面反射镜的准直和聚光效果进行仿真计算,结果表明:焦距相同时,球面镜的聚光和准直效果比抛物镜好,但球面镜对光源位置精度要求更高;当光源尺寸为Φ3.5×6mm2时、抛物镜焦距为15mm,光源能量的利用率最高;对同一焦距的抛物镜,当抛物镜深度大于焦距时,深度改变对结果没有影响。利用仿真结果指导光源和准直系统的优化设计,新系统相对原系统光源功率降低75%,准直系统的尺寸缩小一半,实现AOTF中红外光谱仪的光学系统的优化设计。The simulation calculation of collimating and collecting effects of spherical mirrors and parabolic mirrors of different focal lengths using optical simulation software TracePro was performed. Simulation results show that when focal lengths are the same, spherical mirrors have better collimating and collecting performance than parabolic mirrors, but they have higher requirement on position precision of light source; for parabolic mirrors of the same focal length, change of depth has no influence on the resu...
