The W. M. Keck Exoplanet Tracker is a precision Doppler radial velocity instrument for extrasolar planet detection based on a new technique, dispersed fixed-delay interferometry (DFDI), which allows for multi-object surveying for the first time. Installed at the 2.5-m Sloan telescope at Apache Point Observatory, the combination of Michelson interferometer and medium resolution spectrograph (Erskine & Ge 2000; Ge 2002) allows design for simultaneous Doppler measurements of 60 targets (Ge et al. 2005).
