Using integrated absorption to calibrate optical cavity spectrometers

摘要: Sensitive absorption techniques using optical cavities (such as CEAS or ICOS) generally need the spectrometer response to be calibrated for quantitative measurements. Most calibrations are based on instrument a known, steady state absorption. Such often have drawbacks in terms of cost, complexity, convenience, especially field In this paper, we show that relationship between integrated and known amount absorber provides an alternative calibration strategy yields highly linear curve has low uncertainty. This method is straightforward implement offers practical other strategies.
