The iLocater instrument being developed by Justin R. Crepp, the Freimann Assistant Professor of Physics at Notre Dame, has been featured by the SPIE, the International Society for Optics and Photonics, in a paper describing the detection of planets around other stars. The article by Crepp, entitled “Renaissance of the Doppler technique for exoplanet studies,” was published online on Sept. 10 by SPIE and describes how new hardware will enable breakthroughs in instrumentation performance that could lead to the discovery of nearby worlds that might resemble the Earth.

Unlike previous planet-finding spectrometers which operate with blurry images, iLocater will use adaptive optics to overcome the effects that limit traditional Doppler instruments from reaching their full potential. By sending starlight into the spectrometer via tiny (single mode) optical fibers, iLocater will circumvent a number of issues that preclude existing instruments from measuring subtle radial velocity variations caused by orbiting planets.
