Abstract

When recording holographic optical elements it is often necessary to resort to complex wavefronts which can not be obtained with standard optical components. Such wavefronts can be obtained with aspheric elements or computer generated holograms which introduce many difficulties. Instead, we developed recursive design technique for obtaining the complex wavefronts from relatively simple holograms. These techniques are based on changing the geometries and/or the wavelengths between recording and readout of these holograms. We shall present our design techniques with a specific illustration of a holographic Fourier transform lens. We designed the holographic lens with complex wavefronts which were derived from first step hologram. The results demonstrated much lower aberrations and better resolution over a field ranging to ±6°, than comparable spherical holographic lenses.
