Various biomedical problems suffer from a lack of a fast and reliable imaging technique that enables in vivo imaging deep in the tissue. The issue that obscures deep tissue imaging is the random light scattering. Several imaging techniques deal with these problems from different angels, such as optical coherence tomography, light sheet microscopy or structured light illumination. In the clinical studies rigid or flexible endoscopes are often used for imaging deep in the bodies of animals or in human patients. The flexible endoscopes are formed by a bundle of hundreds single mode optical fibers closely packed in a matrix. Each optical fiber then serves as a pixel of the output image. However, the endoscopes are rather bulky devices that cannot be further miniaturized because of evanescent light leaking between optical fibers. This causes cross-talks that ultimately scramble the whole image.
