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.
