ABSTRACT:
A method and apparatus to illuminate a target. The apparatus can comprise a first lens configured to receive light from the light source, a diffractive optical element configured to receive the light from the first lens and to regulate the light into regulated light, and second lens configured to receive the regulated light and to direct the regulated light onto a selected area of the target.
