Development of Rigid-Endoscope Optical Coherence Tomography System with KTN Optical Scanner

We developed novel rigid-endoscope OCT system with KTN optical probe for a diagnosis in the orthopedic surgery fields. The present system demonstrates that biological image was measured by using KTN optical scanner for having degree of freedom in sample arm as OCT. The system was shown to have a resolution
$14.2\mu \mathrm{m}$
for biological tissue in few mm depth. The 3D-OCT image of human fingerprint was obtained using this OCT system.
