  • System and method for correcting systematic error of, and calibrating for, tilt angle of surface topology sensor head having plurality of distance sensors
    Patent number: 7385214
    Abstract: The invention relates to a measuring arrangement comprising a sensor head (13) that can be displaced over a surface (11) at a distance therefrom in a scanning direction (R), a plurality of distance sensors which are suitable for distance measurement and are interspaced in the scanning direction in a fixed manner, a displacement device for displacing the sensor head (13) in such a way that points of the surface (11) are detected in successive scanning steps carried out by a plurality of distance sensors, and an evaluation device to which the output signals of the distance sensors are supplied. According to the invention, one such measuring arrangement is improved by an angle measuring device (14, 15) for determining an angle value of the sensor head (13) in relation to the scanning direction (R), and for forwarding said angle value to the evaluation device. In this way, systematic measuring errors can be eliminated for the reconstruction of a topography of the surface (11) in the scanning direction (R).
