System description
The Kongsberg Mesotech Flexview is a compact, versatile multibeam sonar.
The Flexview is designed for small observation-class
ROVs where compact size and light weight are key
selection criteria. Flexible and efficient, it is suitable
for applications such as site inspection, clearance,
marine engineering, underwater science, environmental
monitoring, or search-and-rescue assignments.
The removable transducer on the Flexview is the first
of its kind, offering field replacement of a damaged
transducer in the unlikely event of a catastrophic
impact. This innovative design also allows for
transducer configurations to be exchanged, depending
on the job being performed. For example, a low-frequency transducer can detect objects
at a long range, whereas a high-frequency transducer provides high-resolution images
at short range.
Multibeam sonars have an array of transducers that simultaneously transmits pings
(sound pulses) at a specified frequency to cover a large area in less time than a
single-beam transducer. To generate data, computer software assigns a colour range
corresponding to the amount of sound reflected off a target. The distance to the target is
determined by the length of time it took to receive the transmitted acoustic pulse.
The Flexview provides wide-angle full-range
situational awareness and concurrent ultra-short range
imaging with dynamic focusing.
By combining the high refresh rate of a conventional
multibeam sonar with an image quality comparable
to a single-beam sonar, the Flexview provides
high-resolution images that are easy to interpret. The
Flexview has a 140° field of view, allowing you to see
the full underwater picture in real-time.
