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.
