Abstract
Abstract The sensor of the invention comprises a mechanical resonator 1 vibrating at its resonant frequency. The excitation is produced by means of a light beam 3 whose intensity is modulated to this same frequency. A second, linearly-polarised 41 unmodulated 4 light beam passes through the resonator orthogonally to its plane of vibration and is once again linearly polarised 43 at 90 DEG to the first polarisation; analysing the resultant beam shows an amplitude modulated to the resonant frequency of the resonator.
