    • A reading device operates by the placing in interference of a reference signal, in the form of a fundamental wave train, with delayed wave trains constituting the useful signal. The device comprises an interferometer, a first branch (32) of which is traversed by at least said fundamental wave train (14), the first branch (32) being equipped, with means (37, 67, 87) for the generation of quantified delays of said fundamental wave train (14) with means (39) for the generation of a continuously variable delay of said fundamental wave train (14) over a range about each quantified delay value.

    • An optic fiber hydrophone comprises a wide spectrum optical source, a super-luminescent diode for example, associated with an optic fiber assembly comprising chiefly a side-hole optic fiber, subjected to the field of pressure, forming a sensor, transmitting the optic radiation in the slow and fast modes respectively, and a second fiber, not subjected to the field of pressure, the neutral axes of which are oriented with respect to the neutral axis of the first fiber so that the wave transmitted in slow mode in one fiber is transmitted in fast mode in the other fiber, it being possible to connect these two fibers by a polarization maintaining fiber in the event that the sensor is offset with respect to the source, a polarizing fiber enabling the creation of the interferences, and a radiation detector at the output of the fiber assembly.

    • A process for producing an optical fiber comprising the following stages: a stage of production of a preform having an axis of symmetry and their ends and comprising an optical core as well as at least one cylindrical recess whose axis is parallel to the axis of symmetry of the preform; a drawing stage at a temperature making possible the softening of the drawn part of the preform to obtain a hollow optical fiber, characterized in that it comprises, after the preceding stage of production of the preform: a stage of attachment in a tight manner, to one end of the preform, of a hollow chamber whose cavity communicates with the recess of the preform. The cavity also communicates with a pneumatic regulation device. The drawing stage comprises a pneumatic regulation of the gas contained in the cavity and in the recess with the help of the pneumatic regulation device.
