Computer Generated Holograms in Pattern Recognition: A Review

摘要

Holographic optical elements and computer-generated holograms (CGHs) offer many attractive properties and uses. In this review, we consider the use of holography in pattern recognition, with specific attention to recent work with CGH elements. Subject terms: holography; chord distribution; computer-generated hologram; coordinate transformation; correlator; feature extractor; Fourier coefficient; holographic optical element; moment; optical pattern recognition; Sobel transform; space-variant transform; Reprints.
