Three-Dimensional Measurement of Specular Surfaces Using Phase Measuring Deflectometry
The phase measuring deflection is used as a basic technical principle, a measurement system composed of an LED plate display, a measured mirror object and a CCD camera is constructed. The geometric and physical model for general geometric settings and the corresponding calibration method is proposed, which has low equipment, high flexibility and accuracy. The preliminary experimental results of concave mirror demonstrate the feasibility of this method.
