In this paper, the relationship between the coherence and the speckle contrast in a laser-
based projection display system is studied with the consideration of human visual percept …

In laser front projection display, the observer in the far field of the image pixels on the screen
will observe serious speckle noise. For the first time we show a way to eliminate speckles in …

In laser display system, speckle noise produced by laser coherence has a serious effect on
image. The condition for a diffuser to produce the maximum speckle reduction with the …

We have developed illumination optics for image projection systems. It realizes uniform
illumination and suppression of speckle and diffraction noises by using a diffuser and …

A simple method for suppressing speckles in images produced by laser projectors is
proposed. The coherence of the laser beam and, therefore, speckles can be destroyed when …

In laser projection systems the observer in the far field of the image points on the screen will
recognize serious speckle noise. There are many methods to reduce or eliminate speckles …

A dynamic light scattering liquid crystal (DLS-LC) device is applied to reduce speckle from a
laser pico-projector. The DLS-LC device produces time-varying scattering patterns, which …
