Scientific paper

A detailed design approach is given for a low-cost, large aperture laser reciever capable of detecting and recognizing short laser pulses of unknown frequency. The design results from development of three basic rules for detection of extraterrestrial signals. The paper looks at both frequency and time domain issues, and configures a specific design to accomplish detection and recognition. This design enables a large aperture system that costs orders of magnitude less than that of a diffraction-limited astronomical telescope of equivalent capability for detection of SETI laser pulses. Implementation of this design will enable the detection of laser signals, if present, that have previously been undetectable.
