A transmitting unit of a LIDAR device includes at least two radiation sources for generating and emitting punctiform or linear electromagnetic beams into a scanning range, at least one of the radiation sources including an operating temperature settable as a function of an emission angle of the electromagnetic beams generated by the at least one radiation source. The different operating temperatures can generate beams having angle-dependent emission wavelengths, which can result in an improvement of the signal-to-noise ratio of a LIDAR device.

An optical system for detecting a scanning field, a system for controlling the optical system as well as a method for controlling the optical system, the optical system having at least one transmitter comprising at least one source for emitting electromagnetic radiation and at least one deflection unit for deflecting the beam path of the electromagnetic radiation emitted by the source into the scanning field. The optical system furthermore has at least one optical receiver comprising at least one optical filter element for filtering the electromagnetic radiation scattered back and/or reflected in the scanning field and at least one detector element for detecting the filtered electromagnetic radiation. The essence of the invention lies in the fact that it is possible to vary the wavelength of the electromagnetic radiation emitted by the source and that the variation of the wavelength occurs as a function of the deflection of the beam path.

Lidar scanning device and lidar scanning device system

A lidar sensor, especially for motor vehicles, having a light source, a movable deflection mirror for producing a scanning beam that sweeps across a monitored space by deflecting a light beam emitted by the light source, and having an optical receiver for detecting light reflected by an object hit by the scanning beam in the monitored space. The light source and the deflection mirror are adapted for using the deflected light beam to scan an array of micro-optical elements, each of which, in response to being impinged upon by this light beam, widens it into a divergent beam; and, configured at a distance from the array of micro-optical elements, is a light-concentrating element that transforms the divergent beam into a beam which forms the scanning beam and whose beam diameter is larger than that of the deflected beam.

Laser ignition device and operating method therefor

A method is described for producing a light source, in particular a light source for optically exciting a laser device, for example a laser device of a laser ignition system of an internal combustion engine, including a diode laser having a plurality of emitters and a fiber optic device. The fiber optic device includes a plurality of optical fibers, each fiber having a first end and a lateral surface area. The first ends are situated relative to the emitters in such a way that light generated by the emitters is injected into the first ends of the optical fibers. The optical fibers are situated in abutment along their lateral surface areas, at least in the region of the first ends of the optical fibers. The method is characterized by the following steps: arranging a plurality of optical fibers which form a fiber section in a subregion, the fiber section being situated between two opposite pressing surfaces; heating the fiber section; and exerting a force on the heated optical fibers with the aid of the pressing surfaces. The force and the heating initially result in deformation of the heated optical fiber. The exerted force and/or a temperature of the optical fibers is/are selected in such a way that the deformation ceases when the optical fibers for the first time fill, at least largely, a region between the pressing surfaces.
