Title: Guy Claude Travot: Optical and Magneto-Optical Inventions.

Introduction

Guy Claude Travot is an inventor associated with Saint-Maur-des-Fossés, France. His work includes inventions for detecting magnetic fields through optical techniques and reading magnetically recorded information. He is associated with Eastman Kodak Company and holds 2 patents.

Latest Patents

Travot’s listed patents explore how light can reveal magnetic effects and recorded data.

“Optical Detector for Magnetic Fields Employing Feedback Circuitry” describes a detector that measures magnetic-field-induced changes in the polarization of light. A modulator adds a fixed-frequency oscillation to the polarized beam, while a polarization detector and signal-processing circuitry generate a feedback signal. The feedback cancels the polarization rotation caused by the magnetic field, and the signal also serves as the detector’s output.

“Magneto-Optical Readout Apparatus” presents a method for retrieving magnetic recordings using coherent light. The light’s plane of polarization is varied periodically, and the transmitted or reflected light is analyzed to recover the recorded information.

Career Highlights

The patents attributed to Travot demonstrate applications of optical modulation, polarization analysis, and feedback circuitry. Together, they address magnetic-field detection and optical retrieval of magnetically stored information.

Collaborations

Travot is associated with Eastman Kodak Company. His listed coworker is Gerard R. Sirand-Rey.

Conclusion

Guy Claude Travot’s patent work connects optical measurement with magnetic sensing and data retrieval, highlighting two distinct uses of magneto-optical techniques.
