Paper Abstract

Some applications for high energy beam directors will require near diffraction limited performance at near visible wavelengths even in the presence of severe environmental conditions and operational requirements. Telescopes based on the PAMELA architecture appear to be the only viable candidate for such applications which necessitate wave front correction on a spatial scale of a few centimeters over an aperture of 10 to 12 meters. Past work under the sponsorship of DARPA and the SDIO has demonstrated the feasibility of constructing such telescopes based on light weight silicon carbide segments which are 7 cm flat to flat. More recent work has been directed at assessing the feasibility of producing 3 cm segments using single crystal silicon micromachining technology. This paper describes the latest activities and results of this work.
