Latest Patents

Crawford's latest patents include an electro-optic voltage sensor with beam splitting and an electro-optic voltage sensor for sensing voltage in an electric field. His inventions focus on creating a miniature electro-optic voltage sensor and system capable of accurate operation at high voltages. The sensor body is designed to be disposed in an electric field, receiving a source beam of electromagnetic radiation. A polarization beam displacer separates the source light beam into two beams with orthogonal linear polarizations. A wave plate rotates the linear polarization to a rotated state, while a transducer utilizes the Pockels electro-optic effect to induce a differential phase shift on the major and minor axes of the rotated polarization in response to the electric field. The system also includes a prism that redirects the beam back through the transducer, wave plate, and polarization beam displacer, converting the rotated polarization to circular or elliptical polarization. This innovative design allows for precise voltage determination through a signal processor that interprets the electrical signals generated by the detector.
