Abstract
A non-acoustic measurement unit is provided to be integrated into an all-optical acoustic antenna, the non-acoustic measurement unit including a portion of an optical fiber, termed non-acoustic, intended to convey non-acoustic measurements, at least one non-acoustic sensor with electrical output able to deliver at least one electrical signal representative of at least one physical quantity, and a passive electro-optical transducer subjected to the electrical signal, the passive electro-optical transducer acting on a mechanical constraint undergone by a first sensitive zone of the optical fiber portion, in such a way that a value of a measurable property of a first optical signal conveyed by the non-acoustic optical fiber is representative of the electrical signal, and at least one photovoltaic cell coupled electrically to the non-acoustic sensor so as to electrically supply the sensor.
