Title (EN) FLYING SPOT ENDOSCOPE
(FR) ENDOSCOPE A SPOT MOBILE
Abstract:
(EN) A fiberoptic endoscope having a plurality of fiberoptic cores (40, 42) of different refractive indices. The image is scanned and the fixed pattern noise inherent in multi-fiber prior art endoscope is substantially reduced.
(FR) Endoscope à fibres optiques présentant une pluralité d'âmes de fibres optiques (40, 42) d'indices de réfraction différents. L'image est balayée et le bruit de configuration fixe inhérent à l'endoscope multifibres de l'art antérieur est sensiblement réduit.
