Construction of the Optical Delay Line for the Optical Coherence Tomography

Kitsakorn Locharoenrat and I-Jen Hsu

Abstract—We have constructed the compact optical delay line for the axial scanning of time-domain optical coherence tomography. The delay line contains the retro-reflector, and the inclined reflection mirror, as well as the scanning mirror. This delay line is performed by the low-coherence reflectometer with a scanning speed of 400 Hz. The dimension of the delay line is 2 cm × 2 cm. We have achieved the scanning range of about 3 mm within the scanning mirror’s vibration angle of approximately 10°.

Index Terms—Imaging technique, interferometer, optical delay line, reflectometer.
