Abstract :
We report a new method for measuring a beam´s shape at the focus point on a surface using an optical system and a CCD camera. An analytical model based on z-axis movement testing has been proposed, and experimental setups have been developed. Analysis of the obtained results allowed us precisely position the specimen for the focus-point identification.
