Speckle reduction using phase plate array and lens array

In this paper, a solution for speckle reduction using phase plate array (PPA) and lens array (LA) in a motionless way is proposed. The specially designed PPA is composed of sub-phase plates, which are constituted by phase patterns formed by Hadamard sub-matrices. Each component of the proposed optic...
