Abstract:
The present disclosure relates to an optical gas sensor including at least: an optical wave guide including a first elliptical mirror formed along at least part of a first 3-dimensional ellipsoid and having a first focal point and a second focal point, a second elliptical mirror formed along at least part of a second 3-dimensional ellipsoid and having the first focal point and a third focal point, and a third elliptical mirror formed along at least part of a third 3-dimensional ellipsoid and having the first focal point and a fourth focal point; one or more optical sensors installed at at least one of the first, second, third, and fourth focal points; and one or more light sources installed at at least one of the first, second, third, and fourth focal points where the one or more optical sensors are not installed.
