ABSTRACT:
A photoelastic sensing device comprising a photoelastic member of transparent material, first means for supplying polarized light fluxes to the member for transmission therethrough along a plurality of respective paths, and second means for receiving and detecting the transmitted light fluxes. A third means applies stresses to the member in response to the application thereto of force which is variable and has a magnitude and direction represented by its components along a plurality of vector coordinates which define a space of at least two dimensions. The light fluxes which are transmitted respectively along the plurality of paths of the member are each responsive to the stresses in the member along its path, and the second means provides an output signal which is responsive to the force and to each of the components of the force applied to the third means. The output signal is representative of and provides a measure and indication of the force and each of its components applied to the sensing device, and is responsive to the magnitude and direction of the applied force for providing control means.
