Abstract

I report on a new optical technique that uses the principles of speckle photography and wave-front shearing to obtain the measurement of surface strains. The strain information stored at each point on the object surface is read out on a point-wise basis. The method is developed from a theoretical point of view, and experimental results are presented.
