Paper Abstract

In this study, we developed a dark-field illuminated reflectance fiber-optic microscope (DRFM) along with an algorithm for l1-norm minimization of fiber bundle image to provide intrinsic endoscopic imaging with cellular resolution. To suppress specular reflection from fiber bundle facets, we adopted a dark-field configuration. To remove the honeycomb pattern of fiber bundle while preserve image resolution and contrast, we chose to minimize the image l1 norm using iterative shrinkage thresholding (IST) algorithm.
