[Real-time remote detection of weak-spectra of chemical vapors using subtractive spectroscopy techniques].
Infrared spectra from the several typical chemical vapors were observed remotely using the RFX-40 passive Fourier transform infrared spectrometer. In this paper, we discuss mainly the characteristics of infrared radiance transfer of chemical vapors. Subtractive spectroscopy was used to reduce the effect of atmosphere radiance on weak spectrum and enhance the spectral features of the chemical vapors.
