Dynamic photomechanics methods are important tools to research blasting model. Different roles are played by each dynamic photomechanics method in measurement of blasting stress, strain and displacement and corresponding research. In this paper, on the basis of summary of related documents domestic and international, dynamic photomechanics methods in blasting model research are reviewed and commented. And progress of experimental technique and academic research of dynamic photomechanics in different stages are described. Application of dynamic photoelasticity and holographic interferometry in blasting research and its recent development are stressed. Moreover, application of dynamic caustics, moir , moir interferometry and other photomechanics methods in dynamic load research is simply discussed. By analyses from above-mentioned documents, application future and possible direction of these methods are pointed out.
