SYSTEM AND METHOD FOR LASER CALIBRATION

摘要

A laser calibration system and method are described for a laser unit (10) operable to fire a laser beam that is guided along an optical delivery path (310) to a delivery point at a distal end of the optical delivery path. The laser calibration system comprises a laser controller operable to drive the laser unit (10) to fire the laser beam dependent on a desired laser power an d a compensation factor associated with the optical delivery path. A detector (70) generates a measurement signal related to laser power at the delivery point; and a laser calibrator (802) generates an error signal dependent on a comparison (810) of the desired laser power and the measurement signal and t o adjust the compensation factor dependent on the error signal.
