Octopulse is a revolutionary imaging sensor based on ELWAVE's proprietary CEDAR technology, which draws inspiration from electrical sensory perception of tropical freshwater fishes. The compact and lightweight system is ideal for incorporation into a wide range of unmanned underwater vehicles and platforms, including ROVs, AUVs and crawler robots, or mounted on permanent underwater station.

Utilizing an array of up to eight electrodes with cables up to 7 metres in length, the modular system provides highly effective detection, localisation and classification of metallic and non-metallic objects and surfaces, as well as buried objects at depths of 1 to 2 metres. It provides robust performance in water or in air, and in highly noisy environments.

The export restriction-free Octopulse is provided as a complete kit comprising the sensor pod, up to eight electrodes and cables, and all necessary firmware and user interface software.
