Investigation and progress of Dynamic Photomechanics Measurement Based on Ruby Pulse Laser

Technique of instantaneous image grabbing and an electromagnetic pulse loading instrument are presented in this paper.Utilizing pulse ruby laser,the principle and measuring technique of the dynamic holographic photoelasticity,the dynamic speckle interferometry,the dynamic Moire interferometry,the holographic interferometry of underwater explosion,the dynamic electronic speckle pattern interferometry and the dynamic digital speckle correlation methods are introduced,respectively.It shows extensive application prospect in quantitative analysis of dynamic displacement field,strain field and stress field.
