    In order to achieve laser uniform illumination, a new laser homogenization system was designed based on the analysis of regular homogenization technology, and the homogenization technology and the uniformity of laser illumination were researched. The new homogenization system used brushless motor to drive a light shaping scatterer to rotate at a frequency faster than the electronic shutter of cameras, making multiple light superimposed in integration time to form a uniform illumination effect. The new homogenization system can eliminate laser speckles and interference fringes, and realize the purpose of homogenization. Experimental results show that the new homogenization system makes the illumination uniformity reach up to 95% and the energy efficiency reach up to 90% in the effective area. The new homogenization system improves the uniformity of illumination and utilization rate of laser, thus improves the image quality of the illuminated target.
