Title: Innovations of Walter Bernard in Optical Sensor Technology

Introduction

Walter Bernard is a notable inventor based in Meersburg, DE, recognized for his contributions to optical sensor technology. With a total of six patents to his name, Bernard has made significant advancements in the field, particularly through the application of the Sagnac effect in his inventions.

Latest Patents

Among his latest patents is a sensor featuring an optical passive ring resonator that utilizes the Sagnac effect. This innovative sensor employs a passive ring resonator to define a closed light path, allowing light from a broadband source to be coupled in both directions of propagation. The design includes 2x2 couplers that facilitate the coupling of light into and out of the resonator. Additionally, a 3x3 optical coupler is integrated to superimpose light circulating in both directions, creating interference that is detected by a specialized detector.

Another significant patent is the optical ring resonator sensor, which measures physical quantities that induce a non-reciprocal effect, such as the Sagnac effect. This sensor design provides a difference in optical path lengths for clockwise and counter-clockwise light beams within the ring resonator. By coupling a semiconductor laser to the resonator, Bernard's invention generates beams that are frequency-modulated to resonate with the ring. A detector device then responds to the differences in these light beams, producing a signal that indicates the measured physical quantity.
