  • Light pulse detecting system with highly reduced false alarm rate, usable for laser detection
    Patent number: 4897538
    Abstract: The system enables the lowering of the false alarm rate by eliminating, in particular, the spurious pulses created by the detectors themselves. To this effect, it has one or more juxtaposed optical channels to cover the total field. Each optical channel is associated with a pair of detecting elements to form two detecting channels. After amplification and threshold comparison in these channels, the correlation of the two channels is produced to eliminate the spurious signals and select only the useful signal which is simultaneously present on both channels.
