Abstract

A new method for simple and sensitive detection of photothermal strain caused by laser irradiation of plastic plates has been proposed. In-plane strain of the surface is detected directly by optoelectronic detection of speckle displacements at two symmetrical positions about a probe beam. The initial bending of the plate owing to the temperature gradient along the plate thickness is measured and shows good agreement with one-dimensional calculations.
