Holographic Optical Elements (HOE) are used instead of usual glass lenses for incoherent imaging with polychromatic illumination. Such HOE can easily be manufactured either as holograms of real optical systems or as computer holograms. Single HOE suffer from strong chromatic aberrations, these chromatic aberrations, however, can greatly be corrected by combining two or more HOE. Optical transfer functions and photographs for white light and filtered light taken with imaging systems consisting of two HOE are shown. Holographic systems for incoherent imaging show very simple design and manufacture, the experimental results are of comparably good quality.© (1979) COPYRIGHT SPIE--The International Society for Optical Engineering.
