Title: Norbert Furstenau: Innovator in Optical Technologies
Introduction
Norbert Furstenau is a distinguished inventor based in Braunschweig, Germany, known for his contributions to optical technologies. With a total of eight patents to his name, Furstenau has made significant advancements in the fields of optical microphones and measurement systems.
Latest Patents
One of his latest inventions is an optical microphone that incorporates a light source, a fiber optic cable, and a Fabry-Perot interferometer with two reflectors. In this design, one end face of the fiber optic cable serves as a first reflector, while the second reflector is positioned at a distance and can be displaced by fluctuations in sound air pressure. The second reflector is the end face of a glass fiber section that is movable due to induced air pressure via a separate diaphragm. The light source utilized in this invention may be a super luminescent diode (SLD). Another notable patent involves a method and apparatus for measuring acceleration and vibration using a fiber-optic interferometer. This arrangement employs a monomode optical fiber through which light is guided, and upon exiting the fiber, it is reflected back through it, with the exit end capable of transverse vibrations.
