AUTOMATED CALIBRATION OF LASER SYSTEM AND TOMOGRAPHY SYSTEM WITH FLUORESCENT IMAGING OF SCAN PATTERN

摘要

A laser system calibration method and system are provided. In some methods, a calibration plate may be used to calibrate a video camera of the laser system. The video camera pixel locations may be mapped to the physical space. A xy-scan device of the laser system may be calibrated by defining control parameters for actuating components of the xy-scan device to scan a beam to a series of locations. Optionally, the beam may be scanned to a series of locations on a fluorescent plate. The video camera may be used to capture reflected light from the fluorescent plate. The xy-scan device may then be calibrated by mapping the xy-scan device control parameters to physical locations. A desired z-depth focus may be determined by defining control parameters for focusing a beam to different depths. The video camera or a confocal detector may be used to detect the scanned depths.

1. A method of calibrating a laser system with a treatment space, the method comprising:
providing a mapping of sensor surface locations to a treatment space of the laser system, the sensor surface included within a camera of the laser system; scanning an electromagnetic radiation beam of the laser system to a series of scanning locations of a fluorescent material disposed in the treatment space using a scanning system of the laser system by moving the electromagnetic radiation beam relative to a propagation direction of the electromagnetic radiation beam; capturing, using the camera, an emitted light from the series of locations of the fluorescent material in response to the scanned electromagnetic radiation beam; and calibrating the scanning system with the treatment space per the captured series of locations and the mapping of the sensor surface locations to the treatment space.
