Abstract :
In laser ablation of biological tissue, tomography of the tissue surface is necessary for measurement of the crater shape and the crater depth. We demonstrate here automatic in-situ observation of biological-tissue surface in laser ablation by OCT. Depth of a crater of human tooth is measured by these OCT images, and then the ablation rate of 0.21 μm/pule is determined.
