  • Contactless method for determining the ray of a beam, corresponding system
    Patent number: 9194693
    Abstract: The invention relates to a method for measuring a ray r0 of a radiation beam (20), characterized in that it comprises the steps according to which a source (2) of a radiation beam (20) excites (S1) a standard member (1) via heat, in a periodic manner at a frequency (f), thereby obtaining a periodic thermal excitation of the standard member (1); a sensor (3) measures (S2) a periodic thermal response on the part of the standard member, in response to the periodic thermal excitation; a processor (4) determines (S3) a phase shift (?) between the periodic thermal excitation and the periodic thermal response; the source (2) exciting the standard member for a plurality of frequencies (f) and the processor (4) determining a phase shift for each frequency (f), and thereby determining a plurality of phase shifts (?); the processor (4) determines (S4) a minimum ? min of the phase shift (?) thanks to the plurality of phase shifts determined in this manner, and determines (S5) the ray r0 of the beam (20) via the following
