GEAR FOR LASER SOUNDING OF ATMOSPHERE Russian patent published in 1998 - IPC

FIELD: distant measurement of optico-physical parameters of atmosphere. SUBSTANCE: gear for laser sounding of atmosphere has amplifier, amplitude discriminator and pulse former connected in series, counter, address counter and buffer storage which output is connected to computer. Gear is inserted with laser transmitter, dissector tube with focusing/deflecting system, supply gating unit, control unit, scanner, cycle counter, threshold unit, coincidence circuit, address sensor, univibrator, NOT gate and six AND gates. Input of laser transmitter is connected to output of first AND gate. Signal permitting initiation of laser comes to first input of this gate. First output of control unit is tied together with second inputs of first and sixth AND gates and first input of buffer storage. Second input of the latter is integrated with output of address counter and second input of coincidence circuit which first input is connected to output of address counter. Input of the latter is tied together with third input of control unit and second input of fifth AND gate which output is connected to counting input of address counter. Output of the latter is integrated with controlling inputs of threshold unit, counter and output of cycle counter. Output of this counter is connected to output of third AND gate which first input is tied together with output of pulse former and via NOT gate with first inputs of fifth and sixth AND gates. Second output of control unit is connected to first input of second AND gate which output is linked to supply gating unit of dissector tube. Output of pulse former is connected to first input of fourth AND gate which output is connected to counting input of counter whose output is tied together with third input of buffer storage and counting input of threshold unit whose output is integrated with third input of buffer storage and input of univibrator which inverting output is linked to second input of third AND gate. Output of coincidence circuit is tied together with second inputs of third and fourth AND gates, output of sixth AND gate is connected to input of scanner which output is coupled to focusing/deflecting system of dissector tube which output is connected to amplifier. EFFECT: enhanced informativity of collected data and decreased power consumed by system. 11 dwg
