Paper Abstract

Imaging unevenly is a problem to work out in laser display. The cause of imaging unevenly is analyzed in the paper firstly. In order to get even illumination, we use rotating polygon mirror with two-dimensional scanning and lens array to make the intensity distribution of Gaussian function become approximate even distribution. In order to reduce speckles, a rotating diffuser is used in our laser display system to produce the maximum speckle reduction with the minimum number of distinct phase Patterns. Finally the method is experimentally verified by taking example of green light.
