Abstract

L'ENDOSCOPE COMPORTE UN CORPS ET UNE SONDE SOUPLE, LAQUELLE RENFERME DES MOYENS D'ECLAIRAGE ET DE TRANSPORT D'IMAGES. IL SE CARACTERISE PAR LE FAIT QUE LES MOYENS D'ECLAIRAGE SONT CONSTITUES D'UN NOMBRE INHABITUELLEMENT REDUIT DE FIBRES OPTIQUES, CE QUI OFFRE UN GAIN DE PLACE POUR D'AUTRES EQUIPEMENTS DANS LA SONDE. LA REDUCTION D'INTENSITE D'ECLAIRAGE RESULTANTE EST COMPENSEE PAR UN INTENSIFICATEUR D'IMAGES COMPRIS DANS LE CORPS DE L'ENDOSCOPE.THE ENDOSCOPE HAS A BODY AND A FLEXIBLE SENSOR, WHICH CONTAINS LIGHTING AND IMAGE TRANSPORT. IT IS CHARACTERIZED BY THE FACT THAT THE LIGHTING MEANS ARE CONSISTENTLY OF AN UNUSUALLY REDUCED NUMBER OF OPTICAL FIBERS, WHICH OFFERS A GAIN OF SPACE FOR OTHER EQUIPMENT IN THE PROBE. THE REDUCTION OF RESULTANT LIGHTING INTENSITY IS COMPENSATED BY AN IMAGE INCREASER INCLUDED IN THE BODY OF THE ENDOSCOPE.
