Title
(EN) MULTIFIBER ENDOSCOPE WITH MULTIPLE SCANNING MODES TO PRODUCE AN IMAGE FREE OF FIXED PATTERN NOISE
(FR) ENDOSCOPE A MULTIFIBRE ET A PLUSIEURS MODES DE BALAYAGE, SERVANT A PRODUIRE UNE IMAGE DEPOURVUE DE PARASITES A CONFIGURATION FIXE
Abstract
(EN)
A fiberoptic endoscope scanning system with multiple scanning modes. A first mode is a multifiber (20) scanning about its longitudinal axis and a second scanning mode is a chromatic scan, comprising a prism (40) and/or grating at the distal end.
(FR)
Système de balayage à endoscope fibroscopique présentant plusieurs modes de balayage. Un premier mode utilise une multifibre (20) effectuant un balayage autour de son axe longitudinal et un second mode de balayage consiste en un balayage chromatique comprenant un prisme (40) et/ou un réseau de diffraction au niveau de l'extrémité distale.
