Abstract: Equipment includes an image guide ( 1 ) consisting of flexible optical fibers with: on the proximal end side: a source ( 2 ), angular scanning elements ( 3 ), injection elements ( 4 ) in one of the fibers, elements for splitting ( 5 ) the illuminating beam and the backscattered signal, elements for spatial filtering ( 6 ), elements for detecting ( 7 ) the signal, electronic elements ( 8 ) for controlling, analyzing and digital processing of the detected signal and display; and on the distal end side: an optical head ( 9 ) for focusing the illuminating beam exiting from the illuminated fiber. The scanning elements include a resonant line mirror (M 1 ) and a galvanometric field mirror (M 2 ) with a variable frequency and two afocal optical systems adapted to conjugate the two mirrors (M 1 , M 2 ) firstly in the field mirror (M 2 ) and the injection elements ( 4 ) in the image guide in a second step.

Abstract: Il comporte un guide d'image (1) constitué de fibres optiques souples avec : du côté de l'extrémité proximale : une source (2), des moyens de balayage angulaire (3), des moyens d'injection (4) dans l'une des fibres, des moyens de séparation (5) du faisceau d'illumination et du signal rétroémis, des moyens de filtrage spatial (6), des moyens de détection (7) dudit signal, des moyens électroniques (8) de commande, d'analyse et de traitement numérique du signal détecté et de visualisation ; et du côté de l'extrémité distale : une tête optique (9) adaptée à focaliser le faisceau d'illumination sortant de la fibre illuminée. Selon l'invention, les moyens (3) comprennent un miroir ligne résonnant (Ml) et un miroir trame (M2) galvanométrique avec une fréquence variable et deux systèmes optiques d'afocaux adaptés à conjuguer les deux miroirs (Ml, M2) dams un premier temps puis le miroir trame (M2) et le moyen d'injection (4) dans le guide d'image dans un deuxième temps.
