hydrophone arrays

Do you have a need to measure subsea acoustics with a large array of hydrophones? And did you investigate existing hydrophone solutions, but encountered challenges in sensitivity, physical size & weight, power usage, maximum amount of sensing elements and/or complicated (costly) designs?

Optics11 offers a fully optical thin reelable towed array that deals with these challenges. The array consists of miniaturized mandrels  – non metalic – wrapped with optical fiber that operates with high sensitivity @sea state zero behind any surface or underwater platform. Highly sensitive, low weight, small size and low power usage.

Please check our product page for more details on the hydrophones or use the contact button to get in touch.
