Abstract
The present invention relates to a scanning probe (2) for capturing data from a plurality of points on the surface of an object by irradiating the object with a light stripe and detecting light reflected from the object surface, the scanning probe comprising (a) stripe generating means (14) for generating and emitting a light stripe (55); (b) a camera (16) comprising an imaging sensor having an array of pixels to detect the light stripe reflected from the object surface; (c) means for adjusting the intensity of the light stripe (55) during acquisition of the frame, in dependence upon the intensities detected by the camera (16). It also relates to a means to modify the stripe length, a scanner with separate compartment for the processing means, and an attachable dust cover for a scanner.
