摘      要：In this Letter, an autofocusing method in optical scanning holography(OSH) system is proposed. By introducing Lissajous scanning into multiple signal classification(MUSIC) method in time-reversal(TR) OSH, the axial locations of the targets can be retrieved with better resolution and the peak prominence increases from 0.21 to 0.34. The feasibility of this method is confirmed by simulation as well as experiment.
