METHOD AND APPARATUS FOR DETERMINING CHARACTERISTICS OF A LASER BEAM SPOT |
| 摘要 |
<p>A method for determining the dimensions of a laser beam spot (20), comprising: scanning the laser beam (18) in a path across a reference-edge (30) having a photodetector (40) positioned therebehind; and measuring an output signal from the photodetector (40) during the scanning, the output signal corresponding to an area of the laser beam spot (20) incident on the photodetector (40) during the scanning.</p> |
