摘要
提出了一种实时高频角位移测量的新方案,采用该方案可对机载光电系统动态稳定精度进行测试。该方案采用激光自准直测量,以及高精度、高响应频率PSD探测器传感稳定平台的角位移,有效解决了频率达500Hz角振动状态下的稳定精度测量。与传统的脱靶量测试方法相比,精度提高了几个数量级,优于10μrad。该方法可用于机载高精度稳定平台稳定精度的实时测量。
To measure dynamic stabilization precision of airborn electro-optical system,a measurement scheme of angular displacement of real-time variable frequency is put forward. The main characteristics of this measurement are using laser collimation mensurement and position sensitive detector（PSD） with high precision and high response frequency to transducer angular displacement with stabilizing platform. This measurement is stable and accurate at the state of 500 Hz angular vibration. The testing precision of this measurement improves several magnitude orders and less than 10 μrad by contrast with traditional missing amount measurement.
