China tests new laser technology that could track submarines
Chinese scientists say they have successfully tested a laser device that can detect underwater targets at depths never seen before.
The technology may in the future be adapted to track submarines.
Researchers from the Shanghai Institute of Optics and Fine Mechanics said the laser could highlight objects at 160 metres below the ocean – twice as deep as current technology.
"It is the first time [to have reached that depth] … with potential for further improvement," the institute said on its website.
The aircraft-mounted laser system was tested over the South China Sea in April and the results made public this month.
It could be a potential game changer in submarine warfare providing the Chinese military the means to detect a submarine before it entered the country's territorial waters.
...The South China Morning Post reported that the Shanghai researchers were part of China's 'Guanlan' – or Sea Watcher - project. It aims to develop a laser satellite that fires a beam to penetrate 500 metres below the sea surface.
