A sensor for measuring stress, temperature, pressure, sound, etc. comprising an optical fiber waveguide (24 of Fig. 6), a light source (22) which injects light (30) into one end of the waveguide, a deformer (27) contacting and deforming the waveguide to cause light to couple from originally excited modes to other modes, and an optical detector (29) to detect the change in light coupling caused by deformation of the waveguide. |
