摘　　要：斩波器是热释电型热像仪的重要组成部份,其平稳、匀速且按要求相位精确地运转,关系到整机成像质量的好坏。提出了一种对热释电斩波器进行闭环控制的方法,该方法的使用,解决了斩波器的控制问题。Chopper is the important part of the pyroelectric thermal imager. The stable and uniform operation of chopper is related to the imaging quality. This paper presents a method about the closed-loop control for pyroelectric chopper, which solves the problem of the chopper control.

关 键 词：热释电 斩波器 直流电机
