The use of computer generated holograms (CGHs) in aspheric testing is reviewed in light of current capabilites of electron-beam written CGHs. Merits and limitations of various Twyman-Green and Fizeau interferometer configurations are discussed. Methods and guidlines for designing and specifying a CGH are presented.
