ANGLE CHARACTERISTIC OF CURVED HOLOGRAPHIC OPTICAL-ELEMENT

A method of calculating the angle eikonal for curved holographic optic al element is presented. As an example, a Fourier transform holographi c lens is described, where wave fronts of the diffracted waves are con structed from the elementary holographic optical elements. The approac h to the design of holographic lenses can be compared with that of the thin glass lens as its index of refraction tends to infinity. From th is angle characteristic one can find the Seidel coefficients of the th ird order aberrations.
