Optical Wavefront Computer for Stabilizing Large Space Structures
Abstract
This final report investigates a new adaptive optics system architecture for wavefront correction based primarily on optical processing. The highlights are: (1) The design of a new adaptive optics system architecture incorporating optical rather than electronic processing for wavefront sampling and reconstruction. Unlike conventional adaptive systems incorporating electronic processors, the new optical system exhibits a framing rate that is independent of the sampling and reconstruction resolutions. (2) An analysis of requirements and specifications for all major components needed to implement the new optical architecture, including a lenslet array, an image intensifier tube, an optically addressed binary amplitude spatial light modulator, a transmission mask, a computer generated wavefront reconstruction hologram and an optically addressed phase modulator. (3) Design of the minimum mean square error phase reconstruction hologram. (JHD)
