Abstract
Due to the restrictions of size and volume on the 3D scanner for dental applications, it is not easy to perform non-contact profile scanning in the mouth cavity. In this paper, a piezoelectric transducer and collimating illumination based 3D intraoral scanner is presented for the measurement of tooth profiles in the mouth cavity. The phase-shifting technique is used along with an accurate calibration method for the measurement of the tooth profile. Experimental and theoretical inspection of the phase-to-coordinate relation is presented. In addition, a nonlinear system model is proposed for collimating illumination that gives a more accurate mathematical representation of the system, thus improving the shape measurement accuracy. Simulation and optical measurement results are presented to verify the feasibility and performance of the developed system.
