Abstract
Some embodiments may include a method of generating assessment data in a system including a galvanometric scanning system (GSS) having a laser device to generate a laser beam and an X-Y scan head module to position the laser beam on a work piece. The method may include selecting a dimension based on a desired accuracy for validation (and/or a characteristic of an imaging system in embodiments that utilize an imaging system). The method may include commanding the GSS to draw a mark based on a polygon or ellipse of the selected dimension around a predetermined target point associated with the work piece to generate assessment data, and following operation of the GSS based on said commanding, validating a calibration of the GSS using the assessment data (or an image thereof in embodiments that utilize an imaging system). Other embodiments may be disclosed and/or claimed.
