Abstract: This paper presents a stray light scanning test system for the optical remote sensing satellite to simulate, analyze and validate the optical load's stray light suppression before launch. According to the characteristics of the stray light test of the satellite, the stray light scanning system is designed with regard to the safety, the sequence, the effectiveness, the accuracy, the repeatability, the integrity and the communication control, meanwhile the control equation for the beam scanning subsystem is deduced. From the control precision measurements of the stray light scanning system, the positional accuracy is better than 10mm, the azimuth angle accuracy is better than 0.2°, and the pitch angle accuracy is better than 0.1°.
