Abstract:
1. A method of testing a laser eye surgery system, comprising: imaging a known calibration pattern at an image location with an imaging device; establishing an image scale based on the calibration pattern and the calibration pattern image; imageably altering a series of regions of a test surface with an ablation laser beam of the laser eye surgery system at the imaging location; laterally redirecting the laser beam according to an intended pattern between altering of the regions using a beam delivery system so as to form a test pattern on the test surface; imaging the test pattern at the imaging location with the imaging device; determining a lateral redirecting characteristic of the beam delivery system based on the image scale, the intended pattern, and the test pattern image; and qualifying or calibrating the beam delivery system in response to the lateral redirecting characteristic, wherein the beam delivery system laterally redirects the beam along a first axis from a first region to a second region, and laterally redirects the beam along a second axis from the second region to a third region, and wherein the beam delivery system is calibrated by altering machine readable code of the laser eye surgery system so that a subsequent lateral deflection of the beam along the first axis is determined using a first calibration factor, and so that a subsequent lateral deflection of the beam along the second axis is determined using a second calibration factor, the second calibration factor being different than the first calibration factor.
