The visible light dynamic scene projector is a key component of the visible light imaging hardware-in-the-loop(HWIL) simulation test system.With the Digital Micro-mirror Device (DMD) as the key component, a dynamic visible light imaging simulation system was developed which will be used as the hardware in loop simulation platform for a certain type of airborne visible light imaging system.DMD fundamental operating principle and imaging theory are explained thoroughly. According to required,high-brightness RGB LED, aspheric condenser,light rod,relay lens,TIR lens were used to homogenize the illumination light. The optical projection system was specially designed to solve the large diameter and distance of exit pupil.The paper employed mature solution of DMD driving(TI) to achieve scene input,modulation and reproduce. The dynamic scene projector had been successfully applied to the HWIL simulation system of an airborne visible light imaging system, and had high real-time and fidelity, and met the requirements for use
