Design of collaborative target tracking system using digital micro-mirror device

Aiming at the situation that the multi-lens target tracking systems have poor collaboration and the single-lens systems have narrow tracking view field which cannot realize wide field tracking, a coordination tracking system which can track target in wide field and observe local target simultaneously was designed. The system, based on the performance of high reflectivity and field segmentation of digital micro-mirror device (DMD), has good practicability, great realtime performance and simple structure etc. In validation experiments, the width field segmentation system realizes 50ms synergistic imaging cycle, and the less than 2% absolute position error of narrow filed image center adjustment system can make contributions to the solution of overlap problem between local targets beam center and narrow filed imaging system-s axis.
