Definitions
- position is meant within the meaning of the invention a precise location in the space occupied by the blocking point, for example over the entire height of the borehole, and therefore more particularly a depth or a distance relative to the surface.
- Brillouin and/or Rayleigh backscatter measuring equipment comprises a light source emitting a continuous light signal.
- This light source is advantageously embodied by a laser, preferably a DFB (from the acronym “Distributed Feedback”) laser, using a Bragg grating.
- the emission wavelength ⁇ 0 is preferably equal or substantially equal to 1550 nm, at the corresponding frequency v 0 .
- the line of the emitted light wave is centered on the emission wavelength ⁇ 0 and its width is at most 1 MHz.
