We have developed the scanning type laser photoelastic apparatus that possesses high detection sensitivity for measuring the small optical retardation induced by stress. Optical birefringence is measured by a high-frequency modulation method using a photoelastic modulator and polarized laser. A modified synthesized method was developed and applied for the measurement of stress distributions of a glass plate. The distributions of the differences of principal stresses and their directions were obtained directly by a modified synthesized method. The stress distributions of pulled rectangular glass plates with a hole or semicircular notches were measured. The distributions of stress components τ_xy, σ_xx and σ_yy were calculated by the shear difference method. In order to verify the accuracy of results, we analyzed the same problems by finite element method. The stress distributions of τ_xy, σ_xx and σ_yy by the shear difference method agreed well with the analytical results of finite element method. The stress at many points could be obtained quickly by the synthesized method and scanning stress distribution measurement was realized.
