3), after methane gas to be measured (4) absorbs the light that wide spectrum infrared light supply (2) sends, second is opened
Ultraviolet source (7) or the second visible light source (8), irradiate flexible grating (9) lower end and be provided with containing azo
The organic film II (15) of benzene illuminophore, the organic film II (15) containing diphenyl diimide illuminophore deform upon,
Flexible grating (9) pitch change, obtains the spectral information of methane gas multiple components to be measured；
4) spectral information of methane gas multiple components to be measured is delivered to letter by optical fiber by flexible grating (9)
Number acquisition process unit, it is achieved monitoring and the multiple components spectrum analysis in real time of methane gas to be measured.
The method of long-range monitoring the most according to claim 8, it is characterised in that flexible grating (9)
The spectral information of output is delivered to computer (1) by detector (10) and signal conditioning circuit (11),
It is calculated spectroscopic data.
