摘要
为了实现长线列红外探测器双模式成像装置的两种工作模式, 需要在成像装置中增加摆镜控制系统, 而高速扫描时的扫描线性度和静止时的位置稳定精度是本系统设计的关键因素。本文着重论述了摆镜控制系统的整体设计和指标要求, 基于这些指标, 提出了一种高线性和高稳定精度摆镜控制系统的实现方案。并利用 Simulink进行了仿真, 验证该方案切实可行。
Abstract
In order to achieve two operating modes for dual-mode imaging devices with long line infrared detectors, scanning mirror control system is needed in imaging devices. The scanning linearity at high-speed scanning and position stabilization accuracy at reset are critical factors in system design. This paper focuses on the overall design and index requirements of the scanning mirror control system. And based on these indexes, an implementation scheme of a high linearity and high stability precision scanning mirror control system is proposed. The scheme was verified feasible by using Simulink simulation.
