Speckle Reduction by Optimized Multimode Fiber Combined With Dielectric Elastomer Actuator and Lightpipe Homogenizer

Speckle, due to the interference of coherent light having random phases, can seriously degrade image quality in a laser based projection system. The speckle is even worse when the diode pumped solid state (DPSS) lasers are used as light sources since the laser linewidth from the DPSS lasers is usual...
