Abstract

Holographic correction of low-quality telescopes is an inexpensive method of obtaining large aperture devices suitable for lidar, imaging, and directed energy weaponry. We present an analysis of two different methods for producing diffraction-limited telescopes from the holographic correction of spherical mirrors. These evaluations are essential for choosing the optimal design for a given telescope application. Included in our discussion are the results from preliminary experiments into the various designs. The aim of the project is construct the first ever holographically corrected astronomical telescope for both ground and space-based operations.
