ABSTRACT:
An optical alignment apparatus comprising a plurality of subapertures and a plurality of detectors. The subapertures are optically coupled to a reflective surface which formed by a plurality of adjustable reflective segments. Each subaperture falls within one of two subsets. The first subset includes those subapertures that are positioned to receive light reflected from a single reflective segment. The second subset includes those subapertures that are positioned to receive light reflected across the abutting edges of adjacent reflective segments. Each detector is disposed at a focal plane of one of the subapertures and receives light reflected from that subaperture.
