Stray light analysis and suppression of an ultra-high-magnification zoom endoscopy. [PDF]
Biomed Opt ExpressUltra-high-magnification zoom electronic endoscopes are highly susceptible to stray light because compact optomechanical layouts and zoom-dependent optical reconfiguration strongly affect non-imaging light propagation. In compact systems with a small-aperture moving lens group, indiscriminate barrel blackening is not always desirable because coating ...
