Paper Abstract

A technique of great help in the optical test is the subaperture method, this method is proposed to align the segments of a primary mirror of telescope, using the ideal form of the primary mirror, which is defined using the sagita z(x, y). When the surface under test is segmented each segment has a sagita zi(xi, yi) that is rotated and displaced with regard to the reference system of all surface, where i = 1, 2, ..., n, with n is the number of segments. Some numerical simulations are shown to align two segments of a mirror using the subapertures method using the least square algorithm to align the segments.
