Abstract

A symmetric substrate mode holographic doublet that performs Fourier transformation is presented. This doublet is composed of two identical quadratic off-axis holographic lenses which were recorded on the same glass substrate. The first lens couples the light from the input into the glass substrate. The second lens, located at the back focal plane of the first one, couples the light out of the glass substrate and corrects the phase of the emerging wavefront in order to obtain the desired Fourier transformation. In such a configuration the input and the output planes are adjacent to the lenses, so the overall alignment is very convenient.
