Abstract
A Cartesian scanning system for scanning a surface of a sample. The scanning system includes a light source assembly configured to produce at least one collimated beam of light, a light sensing system, a stage configured for mounting the sample thereon and a linear track having a direction of elongation. The linear track and the stage are configured to move relative to each other. The scanning system also includes a scanning head having a reflecting system which is configured to direct the collimated beam of light onto the surface and to direct a beam of light reflected from the surface to the light sensing system. The scanning head is slidably associated with the linear track so as to be moveable in a direction parallel to a direction of elongation of the linear track. Also included are a position determination system and a scan displacement correction system.
