A ‘tango’ between light and mirrors

Francis Torres from The University of Western Australia has developed the mirror device at the heart of a new amplifier technology, which uses an interaction between a high-powered laser and mirror motion to magnify subtle metal, temperature and biological vibrations so they are more easily detected.

“Our idea is to connect the sensors in existing space exploration tools to our amplifier so they can look deeper underground and find smaller and hard-to-find targets such as hidden mineral deposits, water or other bacterial life,” says Francis.

The technology could also enhance the detection sensitivity of Earth-exploration tools and medical sensors.
