As spatial light modulators based on Digital Micro-mirror Devices(DMDs)combined with image sensors could detect strong and weak targets in high dynamic scenes and get high dynamic images,this paper researches the application of DMDs to high dynamic scene image detection systems.Firstly,the application principle of the DMD was introduced,and how to control and drive the DMD in the high dynamic scene image detection system was analyzed.Then,based on DMD's workingcharacteristics,a control driver was designed to make optoelectronic image equipment improve its dynamic range by 66 dB.The main modules were described and working parameters in the system were given.Finally,the feasibility of the system was verified experimentally.The result shows that the control driver detects the strong and weak targets simultaneously in the high dynamic scene,and improves the dynamic range of 66 dB.When a 11 bit higher sensitive imaging sensor is used in the system,the dynamic scene will be over 130 dB.
