ABSTRACT:
A computer generated diffraction grating which exhibits multiple order scattering noise is illuminated by a point source to generate a first wavefront which is intersected with a second wavefront to form a desired interference pattern in a recording medium. The point source is moved relative to the recording medium during exposure in order to reduce multiple order scattering noise.
