Real-time one-dimensional coherent imaging through single-mode fibers by space time conversion processors.
We introduce and experimentally demonstrate a novel technique for one-dimensional coherent imaging through a single-mode optical fiber by use of a pulse shaper and a pulse imager. In contrast to the wavelength-division-multiplexed encoding technique, our approach preserves both amplitude and phase information of the optical signal transmitted through the fiber, allowing one to encode longitudinal in addition to transverse optical information. The effect of the fiber-material dispersion on our imaging technique is analyzed, and potential solutions are discussed.
