Abstract
本发明公开了一种基于PSD的烟雾箱镜面自动校准装置及方法，包括：半导体激光器、光学镜头、二维PSD光电位置传感器、传感器结构箱体、Cube控制器、压电惯性驱动器。在烟雾箱镜面安置准确时，将光学镜头调焦并与PSD、传感器结构箱体垂直组装，半导体激光器激光出射点与光学镜头保持水平，激光经由小镜曲率中心反射至光学镜头中心位置，聚焦到PSD中心位置，光电信号传至传感器结构箱体并上传至上位机作为初始位置坐标，镜面发生偏移后，将采集得到的信号坐标与初始位置坐标对比算出各压电惯性驱动器转动圈数，Cube控制器控制压电惯性驱动器转动，从而达到自动校准。本发明提供的烟雾箱镜面自动校准装置提高了校准的精度和效率。
