SCANNING SENSOR SYSTEM FOR THE NON-CONTACT OPTICAL SCANNING OF OBJECT SURFACES

摘要

Scanning sensor system for the non-contact optical scanning of object surfaces, comprising mutually matched system parts of a sensor head (2) and an optical unit (3). The optical unit (3) can be mounted and positioned in a highly precise manner on the sensor head (2) by means of a mounting device (4). The mounting device (4) has three bearings (20,21,22) on which an optical unit (3) can be mounted and positioned, pressed against the sensor head (2), each of the three bearings (20,21,22) having a pair of shape- and positionally-matched bearing parts (17a, 17b; 18a, 18b; 19a, 19b) with bearing surfaces in which each one of the bearing parts (17a, 18a, 19a) of the bearing part pair is in contact with at least one bearing surface of the other bearing part (17b, 18b, 19b) of the bearing part pair, one bearing part (17b, 18b,19b) of the bearing part pair being arranged on the optical unit (3) and the other bearing part (17a, 18a, 19a) of the bearing part pair being arranged on the sensor head (2). The bearing part pairs are designed such as to impose differing movement restrictions for a lateral movement of one bearing part (17a, 18a, 19a) of the bearing part pair relative to the other bearing part (17b, 18b, 19b) of the bearing part pair in the lateral direction, relative to a bearing plane running through the bearing (20,21,22), namely for a first bearing part pair (17a, 17b), no lateral movement is permitted, for a second bearing part pair (18a, 18b) only a linear lateral movement in one spatial direction is permitted and for a third bearing part pair (19a, 19b) a two-dimensional lateral movement in two spatial directions is permitted.
