Fibre Laser Sensor Array

Thales Australia engineers operating the in board system.

The Fibre Laser Sensor array, jointly developed by DST and Thales Australia, is a sea-bed surveillance array that detects sound with extreme sensitivity using micro-sized lasers embedded in the core of optic fibres. 

The system is very robust, lightweight and ultra-thin and uses minimal electric power compared to the previous electronics-based kinds. It can be rapidly deployed from a rigid hull inflatable boat and brought into operation almost immediately.

During trials in the West Australian Exercise and in Jervis Bay, it successfully detected the sound emissions of vessels of different sizes and sonar signature types, and even detected the presence of Navy divers as well.
