Apparatus and method for line of sight laser communications |
摘要 |
A line of sight laser communication system includes a laser to generate a laser signal with femtosecond pulses. A first grating spectrally disperses the femtosecond pulses of the laser signal. A programmable mask converts the femtosecond pulses of the laser signal into coded words. A second grating spectrally recombines the coded words of the laser signal. A telescope then launches the laser signal. The launched laser signal is received at a receiving telescope. A second laser generates a set of reference pulses. A non-linear crystal combines the set of reference pulses and the laser signal to create an output signal only when the laser signal and the reference pulses temporally coincide. A camera records the output signal.
