Paper Abstract

A new generation system for structured light is proposed here. This light has non-diffraction characteristic and is generated based on Mach-Zehnder interferometer together with optical wedge as the main optical element, which can realize phase shift easily. Theoretical analysis and ZEMAX simulation between the wedge angle and the strip phase shift are carried out. Experimental results show that the new structured light provided by this system has properties of long focal-depth, narrow strip-width, stable spatial sinusoidal density distribution and good contrast of fringe. The phase of the fringe can be shifted by adjusting the optical wedge’s position. The new structured light generated by this system has great advantages over traditional structured light on three-dimensional surface profile measurement which shows good application prospect.
