Optical scanning probe
First Claim
1. A scanning probe for capturing data from a plurality of points on a 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) a stripe generator for generating a light stripe;
(b) an imaging sensor to detect the light stripe reflected from the object surface; and
(c) an aperture through which the light stripe generated by the stripe generator is emitted, the aperture being variable to provide an aperture of a first width and an aperture of a second width through which the light stripe passes such that light stripes of different lengths are generated when the aperture is arranged at different widths.

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.
