Abstract: The invention provides a multiplicity of light sources—such as a planar array of LEDs—and a corresponding multiplicity of primary optic lenses, the primary optic lenses being curved and positioned to narrow a source light beam emitted from each of the light sources, and a beam shaper—which could be a beam shaping micro-refractive film or films, or a segmented refractor lens with multiple facets—that is shaped and positioned to receive a light source distribution emitted from the multiplicity of primary optic lenses and to emit an output light path having an angle of distribution different than a corresponding angle of the light source distribution.

Abstract: This invention in phase homogenization of coherent light from illuminators used for surveillance imaging systems provides a coherent light emitter aligned with a light source ray path along an optical axis with at least two separated microdiffractive diffusers, the microdiffractive diffusers comprising holographically generated surfaces of microdiffractive structure that statistically tend to diffract light at selectable angles or distribution patterns, the microdiffractive diffusers disposed upon a substrate and separated from each other by a distance determined by wavelength phase and irradiance characteristics of the coherent light emitter and by refractive characteristics of at least two microdiffractive diffusers, followed by a homogenized exit ray path in order to produce a diffused pattern of illumination optimized for long distance surveillance imaging.
