Optimized holographic optical elements
Journal of the Optical Society of America A, 1986This paper presents a method for designing optimal holographic optical elements. The method is based on the minimization of the mean-squared difference between the desired and the actual output waves. The minimization yields an integral equation for the grating function of the designed optical element.

Partitioned Holographic Optical Elements
Optical Engineering, 1982A new type of holographic optical element is demonstrated which combines some of the flexibility of computer generated holograms with the large space-bandwidth product and high diffraction efficiency of interferometrically recorded volume phase holograms.

The possibility of storing lightwaves on holographic material can not only be used for recording and reconstructing of three-dimensional objects, but also to deflect lightwaves in an unconventionally manner and for divergent an focusing properties. This kind of specific holograms, which hold imaging properties are called Holographic Optical Elements ...

Computer-originated planar holographic optical elements
Applied Optics, 1998We present novel, to our knowledge, methods for the analytical design and recording of planar holographic optical elements in thick materials. The recording of each planar holographic element is done by interference of two aspherical waves that are derived from appropriately designed computer-generated holograms such that the element has the desired ...

Design for polarizing holographic optical elements
Applied Optics, 1995We present results of the application of a three-dimensional rigorous-vector coupled-wave theory to the design of polarizing holographic optical elements. Two different cases have been selected giving rise to two types of element, one of which is completely original. Experimental realizations were performed.

Wavelength performance of holographic optical elements
Applied Optics, 1985A comprehensive treatment is presented for the diffraction efficiencies of transmission holographic elements and cascade lenses when subject to broad spectral and field angle detunings. Experimental measurements are made in support of our theory on holographic optical elements fabricated in bleached silver-halide emulsions and in dichromated gelatin ...

This article is a survey of the characteristics, technology and applications of Holographic Optical Elements (HOEs), considered as general elements in an optical system. HOEs function by diffraction of light from a generalized grating structure with nonuniform groove spacing. HOEs provide a system of thin film optics.
