  • Device and method for the measurement of inclination and angular stability of electromagnetic radiation beams, and for the measurement of a spatial shift of a focused electromagnetic radiation beam
    Patent number: 12241733
    Abstract: A device for measuring an angular inclination and angular inclination fluctuations of an electromagnetic radiation beam is adapted to detect the incidence angular inclination and the relative fluctuations with respect to a nominal axis of propagation of the beam, in a desired detection plane including the nominal propagation axis. A system and a method for measuring an angular inclination and angular inclination fluctuations of an electromagnetic radiation beam uses the device for measuring an angular inclination and angular inclination fluctuations of an electromagnetic radiation beam. A method measures a spatial shift of a focused laser beam, at the focusing point, with respect to a reference optical axis.
