Patent number: 4399356Abstract: An improved light waveform image sensing system is described. The image wavefront is focused on an image divider and divided into "n"-segments ("n">1) whereupon the "n"-segements are focused on "n"-detector arrays and detected by "S"-detectors ("S">>1) in the "n"-detector arrays.The "S"-detectors may comprise any of the well-known photosensitive elements. A particular useful detector is an electron-beam mode device described in detail herein. The detected signals are combined to produce an electrical signal proportional to the tilt in the wavefront which signal may be used to deform a deformable mirror thereby correcting the image.Type: GrantFiled: January 19, 1981Date of Patent: August 16, 1983Assignee: Adaptive Optics Associates, Inc.Inventors: Julius M.

Patent number: 4141652Abstract: An improved apparatus for sensing wavefront distortions in a return beam of light, such as a beam returned through a turbulent atmosphere or through an imperfect optical system from a radiating or illuminated object is disclosed. This apparatus includes the components typically present in a Hartmann-type wavefront sensor, and additionally includes means to provide a modulated reference beam of light which is combined with the return beam. The use of a modulated reference beam eliminates the necessity for precise optical alignment, which is difficult or impossible to maintain in most operating environments.Type: GrantFiled: November 25, 1977Date of Patent: February 27, 1979Assignee: Adaptive Optics Associates, Inc.Inventor: Julius M.
