The optical route switching which is based on the finite difference absorption radiometric analysis for physical detection

摘要

(57) Abstract The system and method for detecting the substance of one or more are offered. The optical route switch, divides sample route emission into alternate time of the component which the 1st and 2nd polarized light is done. The component which the 1st polarized light is done is transmitted according to 1st optical route, the component which the 2nd polarized light is done is transmitted according to 2nd optical route. The 1st gas less optical filter line, filtering does the component which the 1st polarized light is done in order at least to separate 1st wave length zone, forms the emission which 1st filtering is done with that. The 2nd gas less optical filter line, filtering does the component which the 2nd polarized light is done in order at least to separate 2nd wave length zone, forms the emission which 2nd filtering is done with that. Spectrum absorption of the object substance differs in 110th wave length zone by comparison with 2nd wave length zone.
