Abstract
Some advanced methods of wave-front mapping by coupling of two interferometers are described. Moiré-like superposition of interferograms eliminates certain inherent interferometer errors. Moiré interferometry indicates the direction of the order of interference.The same instrument in different alignment enhances the sharpness of reflection multiple-beam fringes or reverses their contrast for a transmissionlike appearance.Keywords
