Holographic Optical Elements Formed in Light of Reduced Coherence.

Abstract

The theory of holographic optical elements (HOE) made with light of reduced coherence is developed. Both reduced spatial coherence and temporal coherence methods are considered. A theory of broad source fringe formation based on source image distortion is developed. The theory of HOE formation with two zone plates in tandem and under reduced temporal coherence is developed. A new technique of spatial filtering with spatially incoherent light was developed in which the optical system behaves as if the light were coherent (i.e., linear in amplitude and phase preserved) even though the light is spatially incoherent. A technique for obtaining resolution beyond the classical limit (superresolution) was discovered, based on the principle of incoherent to coherent conversion . Keywords: Hologram; Optical element; Interferometry; and Spatial filtering.
