The moire transformation was analysed using communication theory. Based on it, we proposed two new types of phase measurement. The first is a carrier interferometer. It has various applications and advantages, for example, automatic compensation, multiplex recording, shearing of a wavefront, relative compensation of the phase variation in dynamic texts, harmonic interference, etc. The second is a coded mask photographic interferometer using white light. It can be used for measuring strongly varied phase objects.
