In a previous study, we developed the continuous-deformation measurement method which does not require specklegram in static condition and can measure deformation more than 200 micro-meters with 0.1 micro-meter resolution. This method could be applied to deformation measurement along only one direction. We have improved this method and have obtained the new method which can measure deformation along two directions by using two lasers and one color camera. To verify the validity of the method, we carried out deformation measurement of an aluminum plate which was set at a tension testing machine. Results of deformation measurement along two directions are shown. © 2011 SPIE
