Abstract

Improvements introduced into a microendoscope equipped with a device for scanning a surface, characterized in that said device comprises: a) a movable part that is held at one end and that is formed by two elastic strips of magnetizable material, which are arranged one in extension on the other and that they are located in two planes perpendicular to each other, said strips being of such proportions that their mechanical resonance frequencies F1, F2, respectively, satisfy the expression F1 = n.F2 + X, where n, F2 and X are integers, b) a magnetic part, which serves to generate magnetic fields and which is formed by a generator that produces a continuous magnetic field, whose north-south direction is oriented diagonally to the two planes in which the strips are located, and a generator that produces an alternating magnetic field whose direction is mainly parallel to the longitudinal direction of the strips and that or scila with frequencies F1 and F2.
