Directional control apparatus for differential optical absorption sepectroscopy detecting gases in air

摘要

A directional control device for a differential absorption spectroscopy method for detecting atmospheric gas is disclosed.A plurality of light emitting diodes, a plurality of optical fiber arrays coupled to the array in the light emitting diode, an optical transmitter / receiver for receiving the optical signal passed through the open optical path from the optical fiber, An optical fiber array in which the optical fiber array is arranged so as to correspond to the optical output of the optical fiber array; an output optical fiber that provides optical formation; a reflector that reflects the optical signal transmitted from the optical transmitter / receiver; a spectrometer that receives the optical signal reflected from the reflector to the road; Arrangement It comprises a data processing terminal that controls the formation of light, so that between the optical transmitter and the optical receiver it receives the desired optically formed transmission signal with the best focus and can measure it to improve the accuracy.
