Image-free tracking methods based on single-pixel detectors (SPDs) can track a moving object at very high frame rate, but they rarely achieve simultaneous imaging of such an object. In this study, we propose method for simultaneously obtaining the relative displacements and images translational Four binary Fourier patterns two differential Hadamard are used to modulate one then modulated light signals obtained by SPD. The image be gradually along with detection. proposed does not require any prior knowledge its motion. has been verified simulations experiments, achieving rate 3332 Hz acquire spatial resolution 128 × pixels using 20000-Hz digital micro-mirror device. This broaden application image-free obtain information about objects.
