Research On The Driving Technology Of Dynamic Infrared Projector Based On MOS Array

Recent years, infrared detecting technology has been combined with target recognition and tracing technology, So a hardware in loop simulation system that can project different dynamic infrared scene as requried is needed to test the infrared detecting system and the algorithm of target recognition and tracing in laboratory. This can reduce the field experiment times, shorten the research time of the system and cut down the cost of the system.In this thesis, we give a view of the dynamic infrared scene simulation system and infrared projector around the world. Then, a technical scheme of dynamic infrared scene driving system is presented. All design of the hardware components of MOS array driving system are introduced in detail. Solutions to make the signals synchronism in different clock-regions are given And the 32 parallel DACs’ s output are at the same time. Baed on the Software flow chart, we introduce the design data processing and transmission software and devices monitor software.Also we give the structure of software that can control and monitor all the devices automatically. The function of the hardware and software is tested,At last we generate the dynamic infrared scene and measures the relation between MOS array control voltage and the simulation temperature.
