车载近红外变焦距光学系统设计

摘要

A program of near-infrared lamp combining with imaging system can be used to help the driver to increase the viewing distance at night. According to this program, a zoom(6x) near-infrared(750nm-900nm) imaging optical system is designed .A proper optical system is designed in which a Gaussian solution is solved and the aberration is corrected. The cam curve of this zoom optical system is also given in the paper.%为了增加汽车驾驶员夜间的观察距离,可以采用近红外光源配合成像光学系统的方案.本文针对此种方素设计了具有6倍变焦功能,工作波段750～900nm的近红外成像光学系统.设计过程中求取了高斯解,进行了像差校正,取得了较为合理的设计结果.并给出了该变焦距光学系统的凸轮曲线.
