The GFC approach combines extremely high spectral resolution with high optical throughput (or etendue) while avoiding the stringent alignment and mechanical stability requirements imposed by interferometric measurements. Web1.2.1 Gas Filter Correlation Radiometry (HCl, HF, NO, CH 4) Solar energy enters the gas correlation section of the instrument and is divided into two paths for each channel. The first path contains a cell filled with a sample of the gas to be measured; the second is a vacuum path. The output signals from the detector in each of these paths are ... c level interviews
