Issue Date: | Feb-1998 | Citation: | He, Y.M., Tay, C.J., Shang, H.M. (1998-02). A new method for generating and analysing digital speckle shearing correlation fringe patterns. Optics and Laser Technology 30 (1) : 27-31. ScholarBank@NUS Repository. | Abstract: | A method for generating a high visibility digital speckle shearing fringe pattern is proposed. A three-step phase shifting technique which involves the introduction of arbitrary phases is utilized. The phase shifting technique is carried out using a rotating mirror and a theoretical model which involves a linear correlation algorithm is discussed. Experimental results showing correlation fringe patterns and a deformation phase map are presented. © 1998 Elsevier Science Ltd.
