Abstract / Hauptanspruch
A dual-optical displacement sensor system (100) includes a scanner (190) including a first (191) and second scanner head (192) including optical displacement sensors (140a, 140b) providing a first and second beam having a first optical axis (OA) and a second OA. A computing device (140a1) or programmed circuit is coupled to receive time versus position data from measurements involving alignment target(s) including at least one knife edge pair (182) including a first and second knife edge oriented in a first plane of the alignment target that is essentially perpendicular to the OAs positioned between the scanner heads for interacting with the beams, and implement at least one equation to analyze the data for determining a degree of alignment of the first and second OA. Using the degree of alignment, an algorithm is for automatic alignment of the OAs or assist instructions for a user alignment of the OAs that provides guiding steps for the user for the alignment.
