TRANSDUCER BASED ON DIFRACTION NETS IN OPTICAL FIBER.

A transducer (20, 20a, 20b) comprising: a plate (25) comprising a first optical fiber diffraction network (26) located on its upper surface and a second optical fiber diffraction network (27) located in its lower surface, wherein said first and second optical fiber diffraction gratings (26, 27) are configured to translate a change of curvature in said plate (25) in a displacement of the wavelength corresponding to each optical fiber diffraction grating (26, 27). The transducer (20, 20a, 20b) further comprises a first part (21, 21b) and a second part (22, 22a, 22b) joined together through at least one axis (23, 24), said plate being (25) fixed to at least one of the sides of one of the pieces (21, 21b; 22, 22a, 22b), the transducer (20, 20a, 20b) being configured to change the curvature of said plate (25) by means of a change of the angle formed by said first piece (21, 21b) and second piece (22, 22a, 22b).
