中文摘要: The use of lasers in a projection display enables the creation of vibrant images with extensive color coverage. By adding a phase modulators in illumination systems and keeping the most part structures of the classic projection, speckle on the screen and retinas of the observers were restrained. The speckle's form and restraining were simulated. It was obtained form simulations that the contrasts of residual speckle on screen and on retinas are 0.0107 and 0.0132. The simulation proves that speckle on screen and on retinas can be suppressed by phase modulation of the illumination light in projection. It also indicated that the numerical aperture of projector affect the residual speckle on retinas. Experiments of speckle restraining were performed. It confirmed the results of the simulations.
