ABSTRACT:
A transmission grating in which the vertical supports are equidistantly sed from each other in each of the horizontal rows but have their positions relative to each vertical support in all of the other rows determined by a pseudo-random integer of the spacings between the grating wires. As a result, all of the artifacts produced by the vertical supports are eliminated from the diffraction plane.
