title: Spatial frequency sampling by phase modulation as a method of generating multiple images.
abstract: A technique of forming multiple images by an object with phase only periodic transmittance, which acts as a spatial filter, is described. Preliminary experimental results are presented to confirm some of the theoretical predictions.
