摘要：An interferometer including a test plate member having a computer- generatedhologram (CGH) written on the reference surface. In a preferred testing configuration,the interferometer setup includes a laser light source, diverger lens, beamsplitters,collimators, and other auxiliary optics arranged in a common-path (Fizeau-type)configuration to minimize measurement errors for testing an optical test piece with thetest plate member having the computer-generated hologram. By having the computer-generated hologram written directly on the reference surface of the test plate member,the measurement of aspheric optical surfaces is made with greater precision, moreefficient, and with less cost than prior art interferometers and associated methods.
