In this paper, an over-top tracking test system for electro-optical detection device is designed, which provides an overtop test environment for electro-optical detection device by using a two-dimensional motion turntable covering the target source of the infrared and visible light bands in a rolling and pitching shafting system. The electro-optical detection device for two-frame configuration provides over-top tracking function and performance testing and verification conditions.
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
The infrared dynamic scene projector is a key component of the infrared imaging seeker semi-physical simulation system. Aiming at the long-wave infrared imaging seeker system, the design idea of long-wave infrared dynamic scene projector with IR-CRT as the core device was proposed. The working principle of IR-CRT was introduced. The optical collimation system was designed. The key parameters such as resolution, distortion, simulated temperature range and uniformity were tested. The dynamic scene projector had been successfully applied to infrared imaging seeker. The semi-physical simulation system had verified the static and dynamic tracking performance of the infrared imaging seeker, which met the requirements of product use, and promoted the product development process.
