Design and analysis of a novel random phase plate for uniform illumination

Random phase plates have been used in a variety of inertial confinement fusion experimental researches, with the result that uniform illumination of the target planes can be obtained. In the paper we propose such a novel random phase plate, which is composed of phase elements of different shapes and sizes, that the illumination uniformity of the target planes can be improved, to the best of our knowledge, this has not been reported so far, numerical calculations justified our arguments.
