DEVICE FOR MEASURING THRESHOLD OF REMOTE OPTICAL BREAK-DOWN Russian patent published in 2005 - IPC

FIELD: measurement technology.

SUBSTANCE: device can be used for laser probing of elementary composition of atmospheric gases. Device has pulse laser, focusing optical system mounted onto optical axis of pulse laser, beam-splitting plate, two photoreceivers, peak detector, acoustic receiver, time intervals measuring device and computing unit. Beam-splitting plate is mounted onto optical axis of pulse laser between exit mirror of the laser and focusing optical system. Beam-splitting plate conjugates optically exit mirror of laser with input of first photoreceiver and focusing optical system - with input of second photoreceiver. Output of first photoreceiver is connected with peak detector. Output of peak detector is connected with second input of computing unit. Acoustic receiver is tightly fastened to optical system. Output of acoustic receiver is connected with first input of time intervals measuring device. Second input of measuring device is connected with output of second photoreceiver. Output of time intervals measuring device is connected with first input of computing unit.

EFFECT: reduced error of measurement.
