  • Publication number: 20230168083
    Abstract: A system (1) for generating a signal from a surface (22) having a speed V in a direction U, comprising: a light source (2) emitting a Gaussian light beam along a first optical path (11); a sensor (3) able to evaluate the effects of the electromagnetic interference of the first beam; a means (2?, 4) for generating a second Gaussian light beam along a second optical path (12); a second sensor (3?) able to evaluate the effects of electromagnetic interference of the second beam; a focusing lens (5, 6) located on the first and/or the second optical path (11, 12), focusing the light beam at a distance f and defining an upstream optical path (11?, 12?); and a means (4?, 7) for routing the second beam able to redirect the second path (12?) in the direction of the first path (11?).

  • Publication number: 20230168082
    Abstract: A system (1) for generating a signal from a surface (22) having a speed V in a direction U, comprising: a light source (2) emitting a Gaussian beam of light along a first optical path (11); a sensor (3) able to evaluate the effects of the electromagnetic interference of the first beam; an optical splitter (4) located upstream of the sensor (3), generating, from the first beam of light, a second beam of light along a second optical path (12); a focusing lens (5, 6) located on the first and/or the second optical path (11, 12), focusing the beam of light at a distance f and defining an upstream optical path (11?, 12?), and a means (7) for routing the second beam, comprising a mirror redirecting the second path such that the lengths of the first (11?) and second (12?) paths are different.

  • Publication number: 20230168079
    Abstract: A method for obtaining the profile of the outer surface (22) of a medium (21) having a median plane (23) comprising the following steps: obtaining two time signals A and B (1002), for, at each instant, a same geometrical target on a readout line of the outer surface (22); determining at least one Doppler frequency (2001) associated with each time signal A and B; sampling each time signal A and B (2002) at a frequency greater than 2 times the Doppler frequency to obtain a payload signal; determining an envelope (2004) of the payload signal of each signal A and B; performing a relative combination between the envelopes of each signal A and B (3001) to obtain a monotonic and bijective function F; and determining the profile of the outer surface (3002) using a calibration of the function F.
