Laser scanner

A laser scanner device adapted to be mounted to a vehicle, the device comprising:

• a LiDAR module working based on a laser measuring beam and time-of-flight-measurement-principle, wherein all optical components of the LiDAR module are arranged inside a common housing,
• wherein:
• the LiDAR module comprises a multibeam transmitter configured for generating a plurality of measuring beams defining a plurality of essentially instantaneous scanning axes,
• the LiDAR module comprises a receiver for detecting returning parts of the measuring beams as back radiation, wherein the lidar module is configured to determine a set of return signals based on the back radiation, each return signal corresponding to a different measuring beam,
• the common housing has an exit aperture, wherein:
• the exit aperture is common to all measuring beams, and
• the exit aperture limits the theoretically achievable instantaneous horizontal field of view of the laser scanner device with respect to the housing, to less than 180°,
• wherein:
• the LiDAR module is configured to provide:
• a horizontal field of view of at least 60°,
• an instantaneous vertical field of view of at least ±2°,
• a scan resolution of at least one point per 0.8° in horizontal and vertical direction, and
• a frame rate of at least 10 Hz for scanning at least the entire horizontal and instantaneous vertical field of view with said scan resolution.
