Abstract

The variation laws of mutual coherence function in laser projector with moving diffuser for speckle reduction are studied based on the partly coherent theory. We take the magnification of lens and its spread function into consideration, it gives us a method to weigh the speckle reduction and the loss of optical energy while using the moving diffuser for speckle reduction, and it points out the selection of diffuser slice for laser display.
