Infrared Laser System to produce and detect with no physical contact low and very low frequency vibrations

This work presents a device designe to measure resonance frequencies on different kind of materials, either in flexure or torsion modes, acting as a remote sensor for vibrations. This is an extension of an earlier equipment by the same author. Is is constructed as a single unit, including a proximity exciter, can be applied for both ferromagnetic and non ferromagnetic materils, and does not require neither emission of sound nor physical contact.
