Latest Patents

Kirchhofer's latest patents include a fiber-optic voltage sensor and a measuring apparatus for space-resolved temperature measurement. The fiber-optic voltage sensor comprises at least one fiber-optic, piezoelectric sensor element that measures a predeterminable directional component of a local electric field. This sensor is designed with multiple piezoelectric elements arranged serially, each measuring a directional component of the electric field. The arrangement forms an open polygon connecting the two ends of the sensor, with each element's gain proportional to the length of its assigned path element.

The second patent, an arrangement for time-resolved optical backscatter measurement, improves the signal-to-noise ratio in optical waveguides. This is achieved by incorporating an additional filter device that attenuates the Rayleigh peak in the backscattered light. The filter device includes a polarizing beam splitter, a quarter-wave plate, and an interference filter, enhancing the measurement accuracy.
