The previous papers published by the authors discussed the strain-fringe behaviors of polycar-bonate in one-and two-dimensional stress states, and also clarified the dependence of the stress-strain curves on temperature and tensile speed at high temperature. The results indicated the possibility of photoplastic strain freezing. But in some cases of plastic manufacture, the deformation of components is approximately under a plane strain state, giving the rolling and pulling of a wide sheet for example. On account of this, to analyze the strain distribution under a plane strain state by means of photoplastic strain freezing, it is necessary to know the strain-optical behavior at a plane strain state. In this paper, the experiments were carried out based on the plane compress of polycarbonate disk to investigate the strain-optical behavior.
