Implementations include operations for determining inter-transducer correlation matrices of an area of interest and an unwanted area; determining a characteristic matrix of the area of interest from the product of the inverse of the inter-transducer correlation matrix of the unwanted area and the inter-transducer correlation matrix of the area of interest; calculating eigenvectors and values of the characteristic matrix to define a transmission matrix; adjusting the image acquisition rate and image quality in order to define eigenvectors for firing; multiplying a reception matrix comprising the acquired signals completed by data set to zero corresponding to the firings not effected by the inverse of the transmission matrix to obtain a complete data set; reconstructing a high-resolution image of the area of interest as in synthetic aperture echographic imaging methods.

The casing includes at least one portion formed by an extensible and compressible tube extending along the longitudinal axis. The portion formed by an extensible and compressible tube includes an outer end coinciding with one of the two casing ends and can be longitudinally deformed by a difference in the pressures applied on the walls thereof, which results in a variation of the length of the optical fiber as measured by a variation in the wavelength of a luminous flux extracted from the optical fiber.
