Abstract
Systems and methods for testing a laser eye surgery system are provided. Methods include establishing an image scale based on a calibration pattern, imageably altering a series of regions of a test surface with the laser system, laterally redirecting a laser beam to form a test pattern, imaging the test pattern, determining a lateral redirecting characteristic of the beam delivery system, and qualifying or calibrating the beam delivery system. Systems can include an input module that accepts an input member such as a calibration pattern parameter, a calibration pattern image, an intended pattern parameter, a test pattern image, an imaging device position, a calibration pattern position, a test pattern position, and a beam delivery system position, a characterization module that determines a beam delivery system characteristic, and an output module that generates a calibration for the beam delivery system of the laser eye surgery system.
