摘　　要：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。本文针对此种方案设计了具有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。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（6？ 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.
