Abstract
An experimental analysis of noise gratings in holographic lenses is presented. Lenses are recorded as thick-phase holograms in bleached silver halide emulsion. The authors calculated noise grating efficiency by using the diffraction efficiency in points across a lens diameter. They show that due to presence of noise gratings, it is necessary to change the readout geometry of lenses with respect to the recording geometry in order to achieve maximum diffraction efficiency. This change gives rise to aberrations. The root mean square of the wavefront aberration on the entire surface of the lens is calculated for the holographic lens analyzed experimentally.
