ABSTRACT:
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.
