Abstract: A system comprising a scanner to scan an object and a controller. The controller can cause an object to be moved to a plurality of locations to be scanned by the scanner. At each location the controller can cause the scanner to scan the object to create scan data and can cause a reference device to create reference data relating to the object. The scan data can be processed to create scan position data indicative of a measured scan position of the object and can cause the reference data to be processed to create reference position data indicative of a measured reference position of the object. The controller can also cause the generation of error data indicative of a position error in the scan data at each of the plurality of locations based on the scan position data and the reference position data.

An apparatus comprises an optical projection assembly comprising a light source and an optical grating, for illuminating an object with first and second light patterns having different spatial frequencies, wherein the optical projection assembly provides a first light pattern in a first configuration of the optical projection assembly and provides a second light pattern in a second configuration of the optical projection assembly. An image capturing apparatus is used to capture images corresponding to reflections of the first and second light patterns from the illuminated object, and a processing unit is used to identify, from the captured reflections of the first and second light patterns, the effects of distortions in the reflected light patterns corresponding to features of the illuminated object.
