The paper provides a review of a series of studies aimed at the development of adaptive interferometry methods based on the use of dynamic holograms formed in photorefractive crystals. The results obtained in the course of the study made it possible to achieve significant progress in increasing the efficiency of adaptive interferometry methods, increasing their sensitivity, stability and noise immunity. The proposed new schemes of two-, three- and multi-wave interactions on dynamic holograms became the basis for constructing polarization- and non-volatile, as well as multichannel adaptive laser measuring systems, which opened up prospects for their application in solving practical problems in the field of engineering and technical diagnostics, non-destructive testing, biosensorics, nanometry and acoustic measurements.
