摘要： Apparatus for mapping an optical element, the apparatus comprising a light source arranged to transmit a light beam toward the optical element, a beam separator including a plurality of beam separating elements operative to separate the light beam into a corresponding plurality of light beam portions, an optical sensing device operative to generate a light spot map including a plurality of light spots corresponding to said plurality of beam separating elements and an optical element characteristic computation device operative to derive at least one characteristic of the optical element from said light spot map and including apparatus for identifying the beam separating element corresponding to an individual spot based at least partly on information other than the location of the spot.
