Abstract
Device for detecting and measuring very small displacements, characterized in that it includes, in combination, a photoresist and piezoelectric semiconductor crystal, solid or thin-film-shaped, a light source for irradiation of at least one face of said crystal, a stabilized voltage source whose poles are connected to two contacts arranged on faces on either side of the face, or of the radiated faces, an output circuit that includes at least one impedance at the terminals of which it is connected a device for measuring the frequency of the oscillations of the current that pass through the crystal whose value is a function of the irradiated surface, a screen solidary of the organ whose displacement has to be measured and which is arranged between the crystal and the light source, moving in addition, said screen in a plane parallel to the face capable of receiving the light irradiation.
