<p>A sensor for use in an optic system to detect current conditions in an environment. The sensor has a crystal member with a first waveguide extending from a top surface and a second waveguide extending from a bottom surface of a core member. Polarized light waves from a source are simultaneously communicated to the first and second waveguides. A first pressure is communicated to the top surface of the crystal member and an unknown pressure corresponding to the pressure of the environment is communicated to the bottom surface of the crystal member. The first pressure and the unknown pressure develop a pressure differential which act on the crystal member to deform the first and second waveguides. The deformation of the first and second waveguides modify the polarized light waves to create first and second output waves which are communicated to an optical interface where differences therebetween are extracted. The differences are analyzed by a computer to identify the current pressure and temperature of the environment.</p> |
