A Configurable Terasample-per-second Imaging System for Optical SETI
A new instrument for conducting astronomical searches for nanosecond-scale optical pulses has been designed, built, and is now operating at Oak Ridge Observatory in Harvard, MA. The Advanced All-sky Camera, based on the previous generation ASIC-based design, is implemented using Xilinx Virtex-5 LX1...
