Figure 1: A clear image from a speckled view. Choi et al.’s set-up (bottom) allows them to measure the lines on a standard United States Air Force resolution chart with a single, multimode optical fiber. They first characterize the speckled output of laser light transmitted through the fiber for different laser input angles (a sample transmission image is shown top left). These transmission images allow them to work backwards from a series of complex images of the reflected light arriving from the sample (top center) to reconstruct the real image (top right.)
