Abstract

Scanning system is the key system of scanning optical remote sensor. The scanning system pursues high angle measurement accuracy, high control accuracy and high efficiency. The key technologies mainly include scanning mirror and lightweight technology, high precision angle measurement, high precision drive motor, high reliability shafting, low noise angle measurement and control circuit. A new scanning system with high reliability and high precision is presented in this paper. The selection of scanning mirror, shafting, motor and angle sensor, the scheme of scanning control are introduced. A dynamic angle measurement error test and compensation method is introduced, and the influence of space environment on angle measurement accuracy is analyzed. The angle measurement accuracy of space application is better than 1 arc second.
