Abstract

This Letter presents a method for real-time 3D measurements based on three-color digital holographic interfero metry. The optical setup is considerably simplified, since the reference beams are combined into a unique beam. A convolution algorithm allows the three monochrome images to be superposed to provide simultaneous full-field 3D measurements. Experimental results confirm the suitability of the proposed method.
