2. Introduction
Eclipse is a 3D imaging sonar with 3D measurement capability. A single housing
incorporates transmit and receive multi-beam arrays.
Eclipse uses electronic beam-shaping technology, providing a high performance
imaging system which can be used in
3D Volume Visualisation
and
2D
Forward Looking
modes.
By electronically steering the beam, a volume is illuminated ahead of the sonar. This
is converted, in real time, into a full 3D image.
3D Volume Visualisation
provides a realistic graphical representation of scanned objects.
The sonar data can be motion-stabilised by taking in data from an external motion
or tilt sensor.
The sonar data is displayed as a depth palletised 3D volume, where colour represents
the difference between the seabed depth and the vehicle Central Reference Point
(CRP). Eclipse provides data stream logging and replay as well as having image
and volume data snapshot capability. Measurement tools provide range, bearing and
relative position to any acoustic target.
The
Volume Visualisation
has a mode which displays all the individual sonar
contacts as single points. In this mode it is possible to measure the 3D relationship
between two points within the volume.
In 2D mode the Eclipse sonar provides a high update rate which is used to provide
display outputs that can be composed of a number of different sonar images, providing
better display resolution and filter options such as persistence and movement
detection.
