Abstract

In this study, we develop a new optical fiber type of Optical coherence tomography (OCT) with a commercial auto-focus device to simultaneously measure the refractive index and thickness of a single-layer for demonstration. An auto-focus device can be easily implemented into the new OCT in order to diminish the measurement error resulting from the slight vibration of the sample and/or the sample stage. However, if the conventional OCT is implemented with an auto-focus device, it would be extremely difficult in locating and controlling the positions of the sample and scanning stages.
