In order to suppress laser speckle, a metasurface structure with high transmittance and random phase function is designed, which utilizing the basic idea of time-averaged suppression speckle theory. Then integrated with MEMS technology, the design and manufacture of micro-rotation stages is realized, and to achieve a ultra-small speckle suppression device. The experimental results show that the laser speckle contrast can be reduced to 2.63%, which meets the needs of laser projection. This novel laser speckle suppression device is simple in use, high in energy utilization rate, low in cost, and easy to mass-produce.
