Optically switched volume holographic elements
Optics Letters, 1995We optically switched the diffraction efficiency of volume holographic elements recorded in DMP-128 photopolymer by use of a thermal nonlinearity of the liquid crystal 5CB. The liquid crystal was incorporated into the volume grating. The diffraction efficiency of small areas of the grating was switched with a control beam power of several milliwatts ...

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 ...

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.

Advances in holographic optical elements
SPIE Proceedings, 1990Recent advances in the design and recording of holographic optical elements are illustrated by means of two representative examples - focussing lens and multiple beam grating. The focussing lens design method is based on an analytic ray-tracing procedure that yields an analytic solution for the diffractive grating function.
