Abstract

Changes in structureless spectra that are due to the presence of interfering absorbers or light source instabilities, changes in the spectral transfer function of the optics, and changes in the detector’s spectral responsivity degrade measurement accuracy. A method of compensating for changes in structureless spectra is developed for a gas-filter correlation instrument. It is shown that there are points in the spectrum where the effect of the interfering component’s having a structureless spectrum on the measurement can be drastically reduced.
