FOURIER-TRANSFORM HOLOGRAPHIC LENS IN THE TELECENTRIC READOUT CONFIGURATION

The problem of designing a Fourier transform holographic lens, which i mages a finite set of input plane wave fronts into a finite set of out put spherical wave fronts, is considered. An optimal holographic Fouri er transform lens with minimum mean-squared wave front error averaged over the set or input wave fronts is usually described with low values for spherical aberration, coma and astigmatism by permitting distorti on. In this paper, a telecentric readout geometry on the image side wi th reducing distortion is presented.
