Abstract
A method characterizes gas emissions inside an area bounded by first, second, third, and fourth paths. A first spectrometer transmits a first beam along the first path. The first beam is retroreflected back to the first spectrometer, where it is detected to obtain a first signal. A second spectrometer transmits a second beam along the second path. The second beam is retroreflected back to the second spectrometer, where it is detected to obtain a second signal. A third spectrometer transmits a third beam along the third path. The third beam is retroreflected back to the third spectrometer, where it is detected to obtain a third signal. A fourth spectrometer transmits a fourth beam along the fourth path. The fourth beam is retroreflected back to the fourth spectrometer, where it is detected to obtain a fourth signal. The four signals are processed to identify gas sources inside the area.
