Abstract: A method for processing an image acquired through a guide consisting of a plurality of optical fibers includes, for each optical fiber, isolating on the acquired image a zone corresponding to the optical fiber, locally processing each zone individually to correct the photon flux detected in each optical fiber, then reconstructing the acquired image by eliminating the pattern caused by the optical fiber. The method also includes a sampling process for obtaining, for each optical fiber and from a sampling image, a sample injection rate which can be used for reconstructing the acquired images. The method also includes a prior step which consists in detecting the fibers from a target.

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.
