摘要

Color speckle of a fiber-output white laser beam of an RGB laser module is measured. The output beam is projected on thestandard screen. Both speckled and un-speckled far field patterns are obtained. Speckle contrast can be successfully obtained byconversion into a homogeneous background using the un-speckled data.
