Increased Capabilities for Conventional Lidars using Holographic OpticsWhile the field of holographic optics is relatively new, and numerous applications are still being devised and tested, there are good prospects that the use of holographic optical elements (HOEs) may revolutionize the design and applications of optical systems in various fields. This paper is not a review of HOE developments, but rather an account of a particular application, namely the extension of the scanning capabilities of conventional telescopes-in particular, lidar receivers-by means of special holographic accessories. As originally described and in a patent, and in several subsequent publications the HOE lidar was based on the concept of building into the holographic element (either a transmitting one or a reflecting one) all the optical power needed to focus a lidar return to a detector at the HOE's focal point, as well as subjecting the lidar return to both angular deflection and wavelength selection. Results will be reported on the use of Holographic Transmission Gratings (HTGs) at 532 nm and 770 nm at 45 deg. cone angle, both in the laboratory and in the atmosphere at Utah State University.
