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