摘要： A radiation emitting device for emitting light may include a laser light source configured to emit light along an emitting direction, and a non-imaging optical system arranged downstream of the laser light source in the emitting direction. The optical system may include a plurality of optical elements arranged along the emitting direction for shaping a radiation characteristic of the radiation emitting device in a horizontal direction and a vertical direction perpendicular to the horizontal direction, such that the radiation characteristic is asymmetrical along the vertical direction. A first optical element of the optical system may be configured to cause spreading of the light along the horizontal direction; a second optical element of the optical system may be configured to cause collimation of the light along the vertical direction, and a third optical element of the optical system may be configured to cause radiation asymmetry along the vertical direction.

摘要： An optical sensor arrangement, for example for a LiDAR system, includes an emitter unit and a receiver unit. The emitter unit includes a semiconductor laser configured to emit coherent electromagnetic radiation having at least two wavelengths. Furthermore, the emitter unit is configured to direct the emitted electromagnetic radiation at a remote target, the receiver unit including at least one optical sensor configured to selectively detect electromagnetic radiation depending on the at least two wavelengths. The receiver unit is arranged relative to the emitter unit and configured such that electromagnetic radiation scattered or reflected by the remote target is detectable on the optical sensor.
