In this paper, the laboratory research and field application of optical stress meter are discussed. The basic state of optical stress meter installed in different medium materials is emphatically introduced. The effects of different stress ratios on the rate of light stress meter in eight kinds of dielectric materials are listed The streak value is fixed and a set of standard stress fringe pattern is given. The typical application in the field is introduced in this paper. The stress stress and direction of stress are measured by optical stress meter.
