| 摘要 |
A system and method for reducing speckle of a laser beam is disclosed. The system includes at least an active device capable of temporally and/or spatially averaging the speckle pattern of a laser. The device can be used with an external diffuser or have an integrated diffusive layer within its structure to enhance the speckle reduction. The speckle reduction system alters the phase and/or path of light rays within an input laser beam as they pass through a transmissive device or reflect off of the surface of a reflective device. |
