The DMD dynamic infrared scene projector is an integral component of the hardware-in-loop IR simulation system. The time performance parameters of the projector directly affect the accuracy of images projected to the unit under test. The working principle, driving mode and working sequence of the DMD projector were introduced. The demands for time performance parameters such as modulation time, synchronization and frame frequency in the hardware-in-loop IR simulation were discussed. The testing methods of time performance parameters were put forward, and the experimental platform were set up. The time performance parameters of our projector were tested, some problems of the projector were analyzed, and some suggestions for improvement were put forward. These results would provide some reference for DMD projector design, application and performance evaluation.
