Abstract
An example system for downhole measurement disclosed herein comprises a tool to be positioned downhole in a formation, the tool comprising an imaging system to determine measurement information from imaging information obtained by sensing light, and an illumination system to control source light to be emitted by the tool. The system also comprises an optical cable to sense an optical field of view that is remote from the tool, the optical cable including an optical fiber bundle comprising a bundle of imaging fibers to convey the imaging information from a sensing end of the optical cable to the imaging system, and a plurality of illumination fibers positioned outside the bundle of imaging fibers, the illumination fibers to convey the source light from the tool to the sensing end of the cable, the illumination fibers to emit the source light to illuminate the optical field of view.
