| Abstract: | This Paper studies a reflection-type 2-D computer-generated holographic phase grating used in laser coherent imaging Systems as beam shaping elements. In the applications the diffractive gratings must have high diffractionefficiency and produce uniform intensities in the diffracted other desired. In this paper we discuss in some detail theuse of conjugation gratings applied mainly to laser coherent imaging systems with detector arrays to create 2-D gratingstructures that produce multi-fold diffracted beams. |
