interferometric optical fiber acoustic sensor
laser heterodyne acoustic sensor
For the development of new-technic underwater acoustic detection equipment, the State Key Laboratory of Ocean Acoustics needs to test the dynamic data of the underwater acoustic sensor.
Test results indicate that the developed fiber optic acoustic sensors are capable of detecting the acoustic signals propagating in transformer oil with high sensitivity and wide bandwidth.
The MH-60R collects and processes voice, video, radar and acoustic sensor data to alert the Navy vessels it supports of undersea or surface movements and threats.
