Advanced fibre sensing technology

Early in 2007 the Centre for Gravitational Physics at ANU began a $1.2m ARC linkage project with a geophysical services company, Benthic Geotech Pty Ltd, to develop an all-optical, fibre acoustic array for the oil and gas industry. The multidiscipline team has combined sensitive digital interferometric techniques with conventional fibre technology, to create a world class multiplexed, all-optical array. The project is on track to deliver a multiplexed all-optical geophone array with sensitivity in the tens of nano-g, down to infrasonic frequencies.
