Abstract
A novel three dimensional profilometry technique by optical fiber interference projection was presented. Take the wavelength-modulated laser as the light source to make the purpose of interference fringe phase-shift by changing the wavelength of the precision power. Compare with the traditional means what changing the phase by PZT, the new method is easier in phase calibration and phase-shift controlling for its anti-interference and having no hysteresis. In addition, the experimental equipment can be associated with commercial interferometer so that their software can be taken as the tool for data processing.
