In this study, we have developed a high performance microscopic system to perform second-harmonic (SH) imaging on a tooth. The high sensitivity of the system allows acquisition rate of 300 seconds/frame with resolution at 512×512 pixels. The surface SH signal generated from the tooth is also carefully verified through micro-spectroscopy, polarization rotation, and wavelength tuning. In this way, we can ensure the authenticity of the signal. The enamel that encapsulates the dentine is known to possess highly ordered structures. The anisotropy of the structure is revealed in the microscopic SH images of the tooth sample.
