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 ...

Aberration coefficients of curved holographic optical elements
Applied Optics, 1986A general formula is derived that gives all aberration terms of holographic optical elements on substrates of any shape. The spherical substrate shape and the planar substrate shape are treated as important special cases. A numerical example illustrates the need of including higher-order aberrations.

Achromatic Holographic Optical Elements
Journal of Optics, 1978It is shown that the holographic optical elements (HOE) can be achromatised to be used with polychromatic light. The two-elements and three elements achromatic HOE systems possess negative power and hence should be used in conjunction with refractive/reflective optics.

Holographic Optical Element for Visual Display Applications
Applied Optics, 1973Off-axis and off-bisector reflection-type holographic visual display elements have been recorded in dichromated gelatin deposited on planar or spherical shell substrates of glass or Plexiglas. A procedure for bonding gelatin to Plexiglas is given. Holographic elements are recorded at the argon wavelength of 514.5 nm and reconstructed with spectral ...

Photovoltaic concentrator using a holographic optical element
Applied Optics, 1988A photovoltaic concentrator is proposed that uses equatorial tracking (the rotation axis of a concentrator points to the North Star), so that the change of the sun's altitude angle is minimized. The solar concentrator consists of a Fresnel lens (objective), a holographic optical element made on photoresist with 90% diffraction efficiency, and a field ...

Design of a holographic optical element for a pulse compressor
Applied Optics, 1996Nonlinear chirped pulse compression can be theoretically achieved to any order by using a nonplane grating with adequate groove spacing. We evaluate the holographic recording of a grating that compensates to the quadratic chirp. A suitable design is found, and the building tolerances are analyzed.

Holographic optical elements with electro-optic control
2021Although polymeric and liquid crystalline materials have been separately studied for many years, optical devices based the interaction between these two materials in a composite device have come to the forefront of technology in recent years. Liquid crystals typically have strong interactions with the surfaces with which they make contact, with the ...

Curved holographic elements for optical coordinate transformations
Optics Letters, 1991A new method for performing optical coordinate transformation is presented. It is based on a curved holographic element on which the interference pattern of two perpendicular plane waves is recorded. The design procedures and results for two curved elements that perform a one-dimensional logarithmic coordinate transformation and a Gaussian-to-uniform ...

Phase holographic optical elements and geometrical optics
Journal of the Optical Society of America A, 1997In the framework of geometrical optics, we show that the general ray-tracing formula for finding the direction of the diffracted rays for thin phase holographic optical elements located on any arbitrary continuous surface can be derived in a form similar to Fermat's principle.
