摘要： This paper presents a high-speed single-pixel tracking method that exceeds the modulation speed limit of the digital micromirror device (DMD) in conventional approaches. The proposed method adopts a polarization system to split the target image into two identical beams, which are modulated by two orthogonal steady-state geometric moment patterns and input into the dual channels of the DMD. This allows separate extraction of the target's $x$- and $y$-direction positional information without DMD pattern switching. The localization speed is no longer constrained by DMD switching but determined by high-speed single-pixel detectors. Experimental results demonstrate a localization speed of 450 kHz, achieving a one-order-of-magnitude improvement over traditional DMD-based methods.
