Embodiment Construction

[0026] Such as figure 1 and 2 As shown, the optical measuring device 1 comprises a housing 3 and a cover plate 5 , which closes the housing and forms an emission window 10 and a reception window 7 . An emission beam 22 , 24 , such as a pulsed laser light, is emitted through the emission window 10 . According to the present invention, the cover plate 5 is arranged substantially perpendicular to the emission direction, and the emission window 10 has an inclined portion with a predetermined inclination angle. Laser light reflected by objects in the monitored area is received through the receiving window 7 . Using the light pulse travel time method, the distance to objects and / or obstacles identified in the monitored area is calculated using the measured time between the emission of the emission beam 22, 24 and the reception of the reflected emission beam. In the exemplary embodiment shown, the cover plate 5 and thus the emission window 10 and the reception window 7 have an ant...

Abstract

The invention relates to an optical measuring device (1) with a housing (3), in which at least one optical transmitter (20) for emitting at least one transmission beam (22, 24) and at least one optical receiver are arranged, wherein a cover disk (5) closes off the housing and forms a transmission window (10) and a reception window (7), wherein the at least one transmission beam (22, 24) exits from the housing through the transmission window (10). In order to provide a measuring device (1) with as flat an outer surface (14) as possible and to achieve a reduction of interference signals, which can be ascribed to reflections of the transmission beam (22, 24) on the transmission window (10) among other factors, the exterior side (5.1) of a cover disc (5) is arranged essentially perpendicular to the emission direction and the transmission window (10) is designed with an inclination that has a predetermined angle of inclination (alpha).

Description

technical field [0001] The invention relates to an optical measuring device of the type mentioned in the preamble of claim 1 . Background technique [0002] The prior art already discloses scanning optical measuring devices for vehicles, so-called laser scanners or LIDAR (Light Detection and Ranging), for identifying objects and / or obstacles in a surveillance area. These optical measuring devices determine the distance to objects and / or obstacles detected in the surveillance area by means of the light pulse travel time method. [0003] The known optical measuring device comprises a housing in which at least one optical transmitter and at least one optical receiver for emitting at least one emission light beam are arranged. The receiver receives the light beam reflected on the object and / or obstacle and establishes the distance to the object and / or obstacle from the light pulse travel time. The casing is closed by a cover plate, and forms an emitting window and a receiving ...
