Description
Technical field
The present invention relates to the fiber optic sensor technology field, relate in particular to a kind of optical fiber hydrophone towed array protection bracket.
Background technology
Fibre Optical Sensor is compared with corresponding conventional sensors, has remarkable advantages at aspects such as sensitivity, dynamic range, reliabilities, seems particularly outstanding in national defence, Military Application field, is classified as the defense technology of giving priority to by many countries.
Fibre optic hydrophone is all mudulation effects of utilizing the biography light characteristic of optical fiber and it and surrounding environment to interact and produce, surveys the instrument of the underwater sound signal in the water body environment.It is compared with traditional piezoelectric type sensor, and following main advantage is arranged: bandwidth, sound pressure sensitivity height, be not subjected to electromagnetic interference (EMI), in light weight, can be designed to arbitrary shape, and have information sensing concurrently and optical information is transmitted in advantages such as the whole body.
In view of the as above technical advantage of fibre optic hydrophone, can satisfy of the requirement of each developed country in fields such as oil, military affairs, actively launched research at present in this regard.A kind of important application mode of fibre optic hydrophone is the mode of nautical receiving set acoustic array, is widely used in military and the petroleum prospecting.
Yet, to compare with traditional piezoelectric ceramics, optical fiber is in the comparison fragility that just seems aspect physical strength and the survivability.Therefore fibre optic hydrophone often needs the certain protection measure, also is like this in array.When hydrophone array is listed in test, in each link of transporting, load onto ship, lay, pulling, therefore the situation that bends unavoidably, tramples, twists is necessary the fibre optic hydrophone in the array is protected.But, have not yet to see the report of fibre optic hydrophone protective device and method in the Scale Fiber-Optic Hydrophone Array.
Therefore, we propose a kind of optical fiber hydrophone towed array protection bracket, are used for solving the problems such as protection of Scale Fiber-Optic Hydrophone Array fibre optic hydrophone.
Summary of the invention
