This paper describes the development of an improved speckle strain/displacement gauge technique (SSDG). In the conventional SSDG technique, an arbitrary incident angle of laser beam is needed to monitor both various surface strains and displacements. The influence of an irradiation angle and a measurement angle of laser beam on in-plane measurement has already reported in the previous paper. In this study, an application to the out of plane measurement was developed.
