针对双视场成像光学系统的特点，对目前机电主动式温度适应技术需要手动调焦作了改进，采用基于温度传感器的温度信息和视场状态控制调焦机构运动技术，找出不同温度点下调焦镜的最佳位置并写入热像仪伺服控制板主控芯片，实现随环境温度变化自动调焦，达到快速最佳成像的目的。有效保证了双视场红外光学系统在-40℃～50℃范围内的性能。

With the characteristics of IR dual field-of-view optical system, a method of active athermalization by using thermograph and switching zoom system is presented. So this system achieves the best temperature compensation simultaneously by moving the focus lens with the same distance. The moving distance was written into the command chip, and the system can gain the best images rapidly. As the ambient temperature varied, the focus lens moved automatically. This method satisfies the requirement of IR dual field-of-view optical system imaging from -40℃to 50℃.
