Remote ultra-low light imaging (RULLI) for space situational awareness (SSA): modeling and simulation results for passive and active SSA [PDF]
SPIE Proceedings, 2008 Remote Ultra-Low Light Imaging detectors are photon limited detectors developed at Los Alamos National Laboratories. RULLI detectors provide a very high degree of temporal resolution for the arrival times of detected photo- events, but saturate at a photo-detection rate of about 10 6 photo-events per second.
