Micromirror and probe design for dental OCT project with Lantis Laser Inc.

Overview

Optical coherence tomography can be used for high resolution in-vivo imaging of teeth
Present probe designs use ISC and LSF mirror designs for 2D scanning
Linear scanning can be achieved by using empirically derived actuation waveforms.
