  • Page 9: Section 1. System Description

    The laser light emitted from the transceiver unit propagates through the air in the cell to the retrorefl ector and returns to a photodiode detector. In the GasFinderAB a portion of the laser beam is passed through an onboard reference cell to provide line centering. The returning optical signals are converted into electrical waveforms, which the computer processes to determine the actual concentration of gas in the cell.
