Hydrophone and Hydrophone Array technology is enabler of Anti Submarine Warfare

A hydrophone is an underwater listening device, just as a microphone is used to detect sound in the air. Hydrophone detects sounds in the water and converts the acoustic energy into electrical energy by detecting changes in pressure in the surrounding environment. Hydrophones listen to sounds in the sea, but …

Sonar Systems are eyes and ears of ships or submarines in water used to detect, locate and identify mines and track stealthy submarines

Sonar (sound navigation and ranging) is a technology that uses acoustical waves to sense the location of objects in the ocean.  SOund Navigation And Ranging or SONAR is a technique of distance measuring between detector and an object base on sound reflection. The distance can be calculated from propagation time and …

Photoacoustic Imaging enable Seeing Through Solids, hackproof Biometrics and Image Underwater Objects

Alexander Graham Bell discovered photoacoustics by accident when he was working on the development of the photophone, a followup to his recently developed telephone that operated via modulated sunlight instead of electricity. You would operate a photophone by speaking into its transmitter toward a mirror placed inside of it. The vibrations …
