Parameters Analysis for Speckle Suppression in Laser Projection Systems

Optical design of speckle suppression in laser measurement system

“…The current methods of speckle suppression primarily rely on the superposition of uncorrelated or statistically independent speckle patterns, followed by averaging the light intensity over time or space [3][4][5] . However, these methods often give rise to various issues, such as low light energy utilization and limited effectiveness in speckle suppression.…”
