We experimentally and theoretically investigated the performance of a fiber-optic based Fourier-domain common-path optical coherence tomography (OCT). The fiber-optic common-path OCT operated at the 840-nm center wavelength. The resolution of the system was 8.8 \mum (in air) and the working depth us

A novel structure of fiber optic biosensor and its principle are introduced. The sample is detected in microchannels of several microns diameter in fiber optic biosensors. The relation between the optic fiber tapered angle and the fluorescence incident angle is calculated in signal receiving part. A

We propose and demonstrate a scheme to measure the distribution of temperature along an optical fiber based on pseudo-random sequence modulation. In our experimental work, current modulation with a pseudo-random bit sequence (PRBS) is applied to a laser diode that serves as the Brillouin pump light and reference light. Because of the independence of the spatial resolution on the PRBS length, the measurement range can be extended while maintaining high spatial resolution using a long PRBS length.
