Specular Surface Shape Measurement with Orthogonal Dual-Frequency Fourier Transform Deflectometry
Three-dimensional (3D) shape measurement for specular surfaces is becoming increasingly important in various applications. A novel orthogonal dual-frequency fringe is proposed in the specular surface shape measurement to overcome the phase jumping and discontinuities in spatial phase unwrapping. The...
