Instruments Resonator spectrometer Principle of absorption measurements

Resonator spectrometer. Principle of absorption measurements.

A – total relative losses of radiation energy during one traversing of the resonator filled by laboratory atmosphere and measured at frequencies of eigen modes of the resonator.

B– total relative losses of radiation energy during one traversing of the resonator filled by non-absorbing gas (N2)

AB = Atmospheric absorption:
