Flexible and lightweight speckle noise suppression module based on generation of dynamic speckles with multimode fiber and macro fiber composite
Optics & Laser Technology(2020)
摘要
•The speckle reduction module is flexible and lightweight.•Dynamic speckles are time-averaged during the exposure time of a CCD camera.•The most efficient speckle reduction condition is obtained.•High-quality low-speckle projection image in a laser projector is demonstrated.
