Abstract
The present invention relates to optical wave guide having multiple independent optical path and optical gas sensor using that, having an effect of improving optical efficiency by elongating optical path and condensing incident light without a separate artificial structure, by using first focus points of multiple 3 dimensional elliptical mirrors as a common focus point and equipping a light source at a first focus point and optical sensor parts at each second focus points in an optical structure using multiple 3 dimensional elliptical mirrors, and by placing so that virtual lines of first elliptical mirror and second elliptical mirror form a constant angle for improving optical efficiency in a structure equipping a light source at a second focus point of any one of elliptical mirror of multiple 3 dimensional elliptical mirrors and optical sensor parts at each second focus points of another 3 dimensional elliptical mirror.
