Abstract

Endoscopes have been widely used for biomedical imaging applications like surgical guidance and diagnosis. In this project, we demonstrated a beam-shaping system to manipulate the illumination patterns at the distal tip of the multimode fiber by using the real-valued intensity transmission matrix of the MMF for endoscopic applications, which provides the potential to miniaturize the footprint of the structured illumination system and the endoscope geometry.
