This paper introduces a complementary differential detection technique based on dual single-pixel detectors, aimed at achieving rapid focusing. By utilizing dual single-pixel detectors for complementary modulation differential detection, focusing is achieved by identifying the maximum differential in modulation intensity. Existing single-pixel focusing methods require multiple modulation patterns, and their focusing speed is limited by the DMD frame rate.
