High-precision optical field measurement is important for beam quality diagnosis, optical element precision measurement, bio-optical imaging and so on. In this paper, we introduce the basic principle of a new type of optical field measuring instrument which is developed based on phase retrieval technology. Also we introduce the multifunctional applications in measurement of large diameter optical element surface, long focal length lens, laser beam wavefront, optical alignment and optical element thermal distortion. It is a high precision measuring instrument with compact size and userfriednliness.
