Abstract
The LSR module of optical engine in laser display has been designed and discussed in this paper. It has also been tested and verified with the scattering sheet of 5°, 10° and 20°. The experiment demonstrates that the method of rotating the scattering sheet with 10° can effectively suppress laser speckle in our system. It can make the speckle contrast of large power projection system drop to 4.2% < 5%, which reaches the acceptable range of the human eyes.
