Abstract: Systems and methods for measuring an intensity characteristic of a light beam are disclosed. The methods include directing the light beam into a prism assembly that includes a thin prism sandwiched by two transparent plates, and reflecting a portion of the light beam by total-internal-reflection surface to an integrating sphere while transmitting the remaining portion of the light beam through the two transparent plates to a beam dump. The method also includes detecting light captured by the integrating sphere and determining the intensity characteristic from the detected light.

Abstract: The present invention provides methods, systems, and apparatus for calibrating a laser ablation system, such as an excimer laser system for selectively ablating a cornea of a patient's eye. The invention also facilitates alignment of eye tracking cameras that measure a position of the eye during laser eye surgery. A calibration and alignment fixture for a scanning laser beam delivery system having eye tracking cameras may include a structure positionable in a treatment plane. The structure having a feature directing laser energy incident thereon to a calibration energy sensor, at least one reference-edge to determine a characteristic of the laser beam (shape, dimensions, etc.), and an artificial pupil to determine alignment of the eye tracking cameras with the laser system.

Abstract: A scanning system which obtains and displays the spatial energy distribution of a high power laser beam. The beam to be examined is directed toward two knife-edge mirrors arranged to pass only a thin vertical segment of the beam and to reflect the remainder of the beam to power absorbers. The mirrors are scanned across the beam, and a scanning disk having helical slots therein samples the vertical segment, and these samples are directed by means of a paraboloid mirror toward a detector responsive to the wavelength of the laser beam. The output of the detector is placed into storage and thereafter displayed on a high resolution color monitor with different colors representing different energy levels or as a simulated three dimensional display so that an operator may obtain an indication of the spatial energy distribution of the laser beam under examination.
