Abstract:
1. A laser measurement system for determining at least one aspect of a surface, comprising: a laser generating a laser beam, a beam shape corrector for reshaping the laser beam into a corrected shaped laser beam having a corrected energy profile, a measurement shaping element for reshaping the corrected shaped laser beam into a measurement shaped laser beam having an measurement energy profile shaped to be effected by the at least one aspect of the surface, a sensor array for receiving the measurement shaped laser beam after the measurement shaped laser beam has been reflected from the surface and modified by the at least one aspect of the surface, wherein the sensor array includes a plurality of sensors for receiving and measuring corresponding portions a reflected laser beam from the surface, the measured corresponding portions of the reflected laser beam indicate the aspect of the surface, a plurality of sensor arrays for determining a corresponding plurality of the at least one aspect of the surface, a multi-way splitter in the path of the reflected laser beam for directing a corresponding part of the reflected laser beam to a correspond one of the plurality of sensor arrays, the at least one aspect of the surface includes at least one of a tilt of the surface, a curvature of the surface, a warning of the surface, a distortion of the surface and a distance of the surface from the sensor array, and the measurement enemy profile and the plurality of sensors of the sensor array are selected according to the at least one aspect of the surface to the determined.
