Old tricks for new applications December 3rd, 2013

exoStellar intensity interferometer is proposed for observation of exoplanets and other dark space objects. Inspired by quantum ghost imaging and funded by NASA NIAC program, we have carried out an investigation of using star light and intensity interferometer technique to observe space objects such as exoplanets. The study addresses a novel aspect of stellar intensity interferometry, namely, the possibility to observe and characterize dark objects using distortions they impart on spatial coherence of thermal light sources. The initial results of the studied are now published in Physical Review A 88, 053837 (2013)
