Embodiment Construction

[0039] The core idea of ​​the present invention is, inter alia, to provide an improved receiving optics system for a lidar system.

[0040] It is proposed that a receiving device, for example for an optoelectronic 3D scanner, is provided with a reflective surface, wherein the reflective surface can be produced, for example, by applying metal (for example in the form of silver, aluminum, gold, etc.). Further alternatively, by applying a dielectric layer on the reflective face a wavelength selective mirror can be achieved which can simultaneously act as a filter in a 3D scanner and help suppress interfering background light Or minimize distracting background light.

[0041] Thus, the medium filling the space between the mirrors is air, however there is another optically transparent medium (e.g. glass such as BK7, plastic such as polycarbonate, amorphous polyolefin, etc., liquid such as oil) to fill this possibility of space. In the case of this last-mentioned overall solution,...

Abstract

A receiving device (100) for a lidar system (200) includes: a limiting device (1) for limiting an angle of entrance of a received optical beam; two reflector elements (10, 11); and a detector element(20), wherein the received optical beam of the lidar system (200) can impinge upon the limiting device (1) and the limiting device (1) and the two reflector elements (10, 11) are formed and aligned with each other such that the received beam of the lidar system (200) is foldable in relation to an axis of the received optical beam and guidable onto the detector element (20).

Description

technical field [0001] The invention relates to a receiving device for a laser radar system. The invention also relates to a method for producing a receiving device for a lidar system. Background technique [0002] Optical 3D scanners are known in various variants. "Optical 3D scanner" is understood as a rotating macro scanner, MEMS-based scanner, OPA (English Optical Phase Array: Optical Phase Array) lidar, and flash lidar. What all mentioned systems have in common is that all mentioned systems collect the emitted laser light. There are optical systems which consist of a lens or a plurality of lenses. These systems all have in common that they have a long optical receiving path or a plurality of lenses. [0003] As a result, beams with diameters in the centimeter range can be guided in the transmission path by the rotating macromirror. Advantageously, a 360° horizontal field of view (FOV, English, field of view) can be scanned system-immanently by means of such a syste...
