摘要
A Fizeau interferometer is provided with an adaptive null optic whose shape may be selectively varied in a controllable way by the selective application of external mechanical loads to enable the interferometer to be dynamically adapted to testing a variety of aspherical segments of differing shapes without the need for providing individual reference surfaces to match the various shapes of each test segment.
