Abstract

A system for adaptive laser scanning correction includes a laser scanner coupled to a controller. The controller develops control signals for the laser scanner for a directed scan pattern that is modified to compensate for a characteristic scan-pattern distortion introduced by the laser scanner. The laser scanner responds to the control signals to provide an actual scan pattern approaching a target scan-pattern shape. The system may be useful for ophthalmologic laser surgery and other applications requiring precise control over scan pattern shape and a high scanning speed.
