Optical frequency-modulated continuous-wave (FMCW) reflectometry is a ranging technique that allows for high-resolution distance measurements over long ranges. Similarly, swept-source optical coherence tomography (SS-OCT) provides high-resolution depth imaging over typically shorter distances and higher scan speeds. In this dissertation, a novel, low-cost, low-bandwidth ranging and imaging system is presented that provides the high axial resolution normally associated with SS-OCT over meters of depth. The imaging system combines 12 distributed feedback laser (DFB) elements from a single butterfly module to provide an axial resolution of 27 microns. Active sweep linearization is used, greatly reducing the signal processing overhead. A laser phase noise model is derived to provide insight into the measurement accuracy. Various sub-surface, OCT-style tomograms of semi-transparent objects are shown, as well as 3-D maps of various objects over depths ranging from sub-millimeter to several meters. Such imaging capability would make long-distance, high-resolution surface interrogation possible in a low-cost, compact package.
