Pattern generation using a diffraction pattern that is a spatial fourier transform of a random pattern

A. Shpunt (Inventor), Z. Zalevsky (Inventor)

Research output: Patent

Abstract

A diffractive optical element contains a diffraction pattern that is a spatial Fourier transform of a random pattern. The diffraction pattern may be etched or deposited on a surface of the diffractive optical element. Alternatively, a spatial light modulator (SLM) may be driven to project the diffraction pattern dynamically.
