ABSTRACT:
A method is disclosed for displaying images represented by electronic image information, including the following steps: providing a light source; optically modulating light from the light source, the optical modulation utilizing a pixel pattern and a diffraction grating, the pixel pattern being modulated with the image information; providing a schlieren optical system for operating on the optically modulated light; and displaying an output of the schlieren optical system; the diffraction grating being provided with a grating spacing that differs from the pixel spacing of the pixel pattern by an odd multiple of half the grating spacing.
