OBSERVATION DEVICE OF THE INTERIOR OF A BODY THAT PRODUCES A PERFECTED OBSERVATION QUALITY.

摘要

Device for observing the inside of a body, comprising: a group of fibers (300) joined side by side, intended to travel an inner part of the body, comprising an outer or proximal end and an end inside the body or distal end, said fiber group forming an image guide whose ends are arranged in the same order to the two inner and outer ends respectively of said fiber group, means (110, 115) of the proximal side to emit a beam of lighting provided to be routed through the group of fibers from the outer or proximal end to an area of the body to be observed, means (200) of the proximal side to sweep the outer or proximal end of the group of fibers with this lighting beam these scanning means being sent to print successive angular deviations to the lighting beam so as to successively direct the outer or proximal end of each fiber or conju nto of fibers into the group of fibers that form the image guide, so that they form at the inner or distal end of said fiber a secondary light source at a given time, said secondary light source moving successively from one fiber to the another, means of the distal side for extracting a back-diffused beam that comes from the illuminated area and leading it through the group of fibers towards means of the proximal side for receiving said back-diffused beam, means for producing from the back-diffused beam received an image of the illuminated area, and means for sending the light emission means and the scanning means, and cooperating with the image production means, characterized in that it also comprises means (L1, L2, L3, L4, L5) for form a conjugated image plane of the illuminated area inside the body, as well as a filtration hole (600) to spatially filter the received backspray, the hole located upstream of the image production means being in the conjugate image plane of the illuminated area inside the body and arranged so that only the back-diffused light exits the lower or proximal end of the fiber directed in a given moment is treated by said means of image production.
