Abstract: A magnetic field sensor for detecting a magnetic field. The sensor includes a magneto-optical material, an excitation light source configured to emit excitation radiation for exciting electronic states of the magneto-optical material, a microwave source configured to generate an electromagnetic field for feeding a resonator structure, a detector configured to detect fluorescent radiation that the magneto-optical material may emit as a result of irradiation with the excitation radiation, a magnetic field generating apparatus arranged and configured to generate a permanent magnetic field in the region of the magneto-optical material, a resonator structure, arranged on a dielectric, configured to shape the electromagnetic field emitted by the microwave source in such a way that a microwave field is created that is suitable for manipulating spin states of the magneto-optical material.

Abstract: A device for transmitting a signal with the aid of waveguides in rotating systems. The device includes at least one transmitting waveguide and at least one receiving waveguide. The at least one receiving waveguide and the at least one transmitting waveguide being divided into multiple radially distributed segments. The radially distributed segments of the at least one receiving waveguide each include a tap. An adder for adding the signals obtained with the aid of the taps of the radially distributed segments of the at least one receiving waveguide is also provided.

Abstract: A LIDAR system of the scanning type for the optical detection of a field of view a working device and/or a vehicle. The LIDAR system includes a stator, a rotor able to rotate about an axis of rotation in relation to the stator, a transmitter optics, a receiver optics and a communications unit for the contact-free data transmission between the stator and the rotor. At least part of the transmitter optics and/or part of the receiver optics is/are accommodated in the rotor, the communications unit has a first communications channel for the contact-free data transmission from the stator to the rotor, and a second communications channel for the contact-free data transmission from the rotor to the stator, and the first and the second communications channel are of a different nature.

Abstract: A method for controlling an emitted light output of a light source of an optical sensor system, in which a portion of the emitted light output is represented in an electrical signal, a characteristic variable of the signal representing a pulse energy of an emitted light pulse is determined, and a control signal for the light source is provided using the characteristic variable and a setpoint value of the characteristic variable.
