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.

A first telescope launches the laser signal. A second telescope receives the laser signal. A second laser generates a set of reference pulses. A non-linear crystal combines the set of reference pulses and the laser signal so as to create an output signal only when the laser signal and the reference pulses temporally coincide. A detector records the output.

Apparatus and method for high bandwidth laser-based data communication

Method and apparatus are presented for snaring explosive, combustible, and other hazardous compounds in vapor and in particulate form, and also combustion residues, which system can be used to prevent, or retrodict the cause of explosions, fires, etc. after they have occurred. The snares are in the form of gated chambers on rotating time disks and moving belts which are used to capture molecules and particulate matter. The combination detects hazardous molecules and combustible particles or causes of dust explosions; and indicates an approximate time-history record of the evolution of particles before or during the course of fires and explosions, or other onerous occurances.
