Ascertaining a laser beam contact point

A method of determining a contact point of a laser beam on an edge of a body and a system for performing the same, in which the method includes a) moving the laser beam relative to the edge in a spatial direction until the laser beam touches the edge, in which the spatial direction is at a right ang...

Zusammenfassung:A method of determining a contact point of a laser beam on an edge of a body and a system for performing the same, in which the method includes a) moving the laser beam relative to the edge in a spatial direction until the laser beam touches the edge, in which the spatial direction is at a right angle relative to an axis of the laser beam and in which the edge is formed at an opening, b) measuring acoustic oscillations produced photoacoustically during the movement of the laser beam, and c) determining the laser beam point of contact with the edge based on the measured acoustic oscillations.
