DEVICE FOR OPTICAL CONTROL OF PRODUCTION ATMOSPHERE Russian patent published in 2009 - IPC G01N21/59 

FIELD: physics, measurement.

SUBSTANCE: invention is related to metering equipment and may be used as facility for continuous measurement of gases and dust concentration. Device comprises source 1 of optical pulses radiation, multichannel analyser 2, fibre optic coupler 3, external detector 4, which comprises body 5 containing collimating lens 6 and bundle of optic fibres 8, which is connected on one side to optic fibre 7, and on the other side forms fibre optic header 9, which is installed in focal plane 10 of collimating lens 6, and also time discriminator 11. At that source 1 is arranged in the form of fast-acting semi-conductor lasers. Treatment of sent and received electric signals is done by controller 12. External detector 4 is installed in investigated volume of production atmosphere 13, which is limited by wall 14 (obstacle).

EFFECT: provision of possibility of optical control of atmosphere in volume of production room and increased validity of measurements with preservation of their accuracy.
