Abstract

The influence of the parameters used in synthesizing hologram projectors on the distribution of complex amplitude in the planes of hologram synthesis and the reconstructed image is considered. A method for increasing the depth of field of the reconstructed images is proposed and investigated. This method is based on the representation of the object wave in the synthesis of a hologram in the form of a superposition of object waves emanating from two identical objects, which are located at different distances from the plane of the hologram synthesis. The work involved mathematical modeling of the processes of synthesis and reconstruction of a hologram for the synthesis of the hologram projectors of two-dimensional binary objects for photolithography.
