摘 要：
<P> Sensor device for the
measurement of force and pressure,
provided with a monomode optical fiber 1 in which polarized light is introduced and is received at the output of the fiber by a detection assembly 4, 80, 81, 30, 40, 31, 41 sensitive to the polarization of light. The detection assembly being provided with means 30A, 31A for analyzing the light in at least two different directions of polarization forming between them an angle between 30degre (s) and 60degre (s). According to the invention, the device is provided with means 70, 71, 2 for
introducing at the input of the fiber several uncorrelated and polarized lights each in a different way, and means 4 for
distinguishing one from the other in the
