Paper Abstract

We study the imaging performance of hololenses formed with four different geometries through an analysis of their third-order aberration coefficients. It is found that the geometry proposed by Brandt [Appl. Opt. 8(7), 1421-1429 (1969)] gives the least residual aberration with minimum variation of this aberration with the reconstruction angle. When the ideal position of one of the construction beams is changed in order to generate a hololens array, the residual aberration is found to increase sharply, which in turn affects the image resolution among the multiplied images in the output. We have generated a hololens array using Brandt's geometry with the help of a 1-D sinusoidal grating. The results of multiple imaging with the hololens array are presented. The image resolution is reasonably high and can be further improved by reducing the f-number of the hololenses.
