Lidar device and method for scanning scanning angle and for evaluating detector

[0024] figure 1 A schematic diagram of the lidar apparatus 1 according to the first embodiment of the present invention is shown. The lidar device 1 is used in particular to carry out a method for scanning within a scanning angle 2 and for evaluating the detector 4. According to this embodiment, the lidar device 1 has a beam source 6 which is an infrared laser 6. The beam source 6 can generate a pulsed or continuous electromagnetic beam 7 or infrared beam 7. The beam 7 is emitted into the scanning angle 2 through the unit 8. According to this embodiment, the unit 8 is a collimating optics. Additionally, the unit 8 may include a rotatable mirror (the rotatable mirror may alternatively be a stationary mirror), a filter, a prism, and the like. The unit can optionally change the exit direction of the beam 7 so that the beam 7 preferably illuminates the entire scanning angle 2.

[0025] If the object 10, 12, 14 is located within the scanning angle 2, the generated beam 7 is reflected
