Clariscan is Kongsberg Mesotech’s latest innovation in domed sonar technology. Clariscan combines the Company’s wide-bandwidth composite transducer with a patented acoustic lens to provide unprecedented image
clarity from a domed sonar head.
- New patented acoustic lens technology
- Improved image resolution and sharpness
- Improved operating range and frequency
Domed Sonar Background
In the 1990s, designers enclosed the transducer in an oil-filled dome to provide mechanical protection and eliminate flooding due to O-ring failure on the traditional exposed transducer shaft. While
the oil-filled dome solved the O-ring flooding failures, it introduced beam defocusing in two conditions, warm & shallow and cold & deep. The beam defocusing effect becomes more extreme in warm shallow
water as temperature increases and cold deep water as depth increases. Until now, there has been no solution to this problem, aside from using a high-resolution scanning sonar head.
Mesotech engineers solved this problem by designing a patented acoustic lens that maintains beam focus through operational temperature and depth changes, significantly improving sonar performance and
resulting in images that are much sharper. The Clariscan acoustic lens behaves like an optical contact lens, correcting the refraction caused by the oil in the dome.
Clariscan is currently available in the 4000M depth-rated version.
