Endoscopic Camera Control by Head Movements for Thoracic Surgery [PDF]

open access: yes, 2010
In current video-assisted thoracic surgery, the endoscopic camera is operated by an assistant of the surgeon, which has several disadvantages. This paper describes a system which enables the surgeon to control the endoscopic camera without the help of an

Extended field-of-view in a lensless endoscope using an aperiodic multicore fiber

open access: yes, 2016
We investigate lensless endoscopy using coherent beam combining and aperiodic multicore fibers (MCF). We show that diffracted orders, inherent to MCF with periodically arranged cores, dramatically reduce the field of view (FoV) and that randomness in MCF
