The Australian Institute of Physics Congress ends today in Brisbane. Among the numerous research presentations was the description of a new optical chip for telescopes that should help astronomers tease out the image of a planet through thermal imaging, nulling out the light of the host star. The new photonic chip could be a replacement for bulk optics at the needed mid-infrared wavelengths.
Harry-Dean Kenchington Goldsmith, a PhD candidate who built the chip at the Australian National University Physics Center, says that the same technology that allows astronomers to penetrate dust clouds to see planets in formation will also be used to study the atmospheres of potentially life-bearing planets. ANU’s Steve Madden describes the chip as an interferometer that “adds equal but opposite light waves from a host sun which cancels out the light from the sun,” making it possible to detect the much fainter light of a planet. He likened the chip’s operation to the methods used in noise cancelling headphones.

If it works, this will have all manner of applications closer to home.
