Description

Technical Field

[0001] The utility model relates to the technical field of screen vibration devices, in particular to a silencer vibration screen motor and a dot matrix type ultra-quiet speckle elimination system. Background Art

[0002] The light emitted by a laser beam will form countless independent scattered sub-waves after being reflected or transmitted by a rough surface. These sub-waves will coherently superimpose during spatial propagation, forming randomly and irregularly distributed bright and dark spots in space, or forming interference patterns in the image plane through an imaging system. Such interference patterns are called speckles.

[0003] There are generally two ways to eliminate speckle. One is to eliminate it from the source, which is to convert the speckle light into speckle-free light before the light comes out. This method requires a high technical threshold. The other is post-processing, which is to superimpose multiple unrelated speckles in the space or time domain after the light comes out, and eliminate them by reducing the contrast. Although this method is easier to operate, the processing effect is not good.

[0004] In order to solve the above problems, the utility model provides a silencer vibration screen motor and a dot matrix ultra-quiet speckle elimination system to solve the problem of poor speckle treatment effect and easy noise pollution. Utility Model Content
