This project aims to improve spectrographic design in order to increase precision in astronomical research. The discovery of Earth's twin, a habitable world in another stellar system, is one of the most remarkable scientific endeavours of our time. The gravitational tug of the planet on its host star causes a periodic Doppler shift of the star’s spectrum which is recorded using spectrographs. The instrumental precision required to detect an Earth-like planet is a few centimetres per second, significantly better than the best current spectrographs can provide. This project plans to combine novel technologies from adaptive optics and astrophotonics into an innovative spectrograph design that will improve Doppler precision by a factor of ten, sufficient to find planets.

该项目旨在改进光谱设计，以提高天文研究的精度。发现地球的孪生兄弟，另一个恒星系统中的可居住世界，是我们这个时代最引人注目的科学努力之一。这颗行星对它的宿主星星的引力会导致星星光谱的周期性多普勒频移，这是用摄谱仪记录下来的。探测类地行星所需的仪器精度是每秒几厘米，比目前最好的光谱仪所能提供的要好得多。该项目计划将自适应光学和天体光子学的联合收割机新技术结合到创新的光谱仪设计中，将多普勒精度提高十倍，足以找到行星。
