A proposed method for a photon-counting laser coherence detection system to complement optical SETI.

BENTON D.M.

Abstract (from CDS):

The detection of laser radiation originating from space is a positive indicator of Extra Terrestrial Intelligence (ETI). Thus far, the optical search for ETI (OSETI) has looked for enhanced brightness in the form of either narrow-band spectral emission or time correlated photons from laser pulses. In this paper, it is proposed to look for coherence properties of incoming light in a manner that can distinguish against atomic emission lines. The use of photon-sensitive detectors and a modulating asymmetric interferometer has been modeled. The results suggest that the sensitivity of detection for continuous laser sources would be better than current spectroscopic approaches, with detection thresholds of <1 photon s^–1 m^–2 against a background with a spectral bandwidth of 0.1 nm over an observation time of 750 s.
