摘要：The device (10) has a telescope including a flat image sensor (5) e.g. CCD chip,arranged in an image plane (4) of a magnifying objective (3), and capturing an image of alaser beam (L) incident on the objective. A natural inclination compensator and anevaluating unit (7) determine an image position of the beam captured in the image basedon image processing, and quantify a laser beam horizontal trueness by converting thedetermined image position into a laser beam inclination value based on a conversion rule,which relates to calibration parameters that depend on a position of the sensor.Independent claims are also included for the following: (1) a system of a laser beamhorizontal trueness-testing device and a laser beam projection device (2) a method fortesting a laser beam horizontal trueness of a laser beam projection device.
