| Abstract: | Stroboscopic laser speckle defocused photography,a new technique for measuring the dynamic behavior of a plate form structure,is put forward.A high quality of whole field speckle fringe pattern can be obtained and the point-by-point filtering method can also be used to analyse the deformation more accurately.The method of choosing the laser pulse width is discussed.Experimental results using the stroboscopic speckle de focused photography arc given. |
