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 using a bare fiber probe was approximately 1.5 mm. The signal-to-noise ratio (SNR) of the system was analyzed. OCT images obtained by the system were also presented.
