Design of tooth color measurement system based on silicon double P-N junction color sensor

Abstract

Working principles of silicon double P-N junction color sensor are introduced and a color measurement system to distinguish tooth color difference is designed in this paper. This system consists of silicon double P-N junction, a small optical fiber probe, signal process circuit and an MSP430FG439 single-chip system. Small in size, this system can measure different parts of the tooth in a fast and convenient way with high-accuracy. Thus, this system will be very promising in building prosthodontics and tooth fabrication.
