The speckle elimination device has the advantages of simple and compact structure, good speckle elimination effect, low construction cost, high laser utilization ratio, stable performance, safety, reliability and light homogenizing ability, and is easy to implement.

Description

technical field [0001] The invention relates to the field of display technology using coherent light as a light source, in particular to a speckle elimination device based on field-induced deformation polymers, mainly aimed at the optical speckle phenomenon existing in laser display technology and optical instruments. Background technique [0002] When the laser is used as the light source to irradiate the screen, due to the coherence of the laser and the roughness of the screen, the human eye sees an image covered by speckle, which seriously affects the image display quality and prevents the observer from extracting useful information from the image. Therefore, how to eliminate speckle has always been a research and development hotspot in the field of optical instruments and display technology with laser as the light source. As far as the current research results are concerned, the methods used to eliminate speckle can be roughly divided into two categories: 1. Reduce s...
