Abstract
A measuring device is provided for measuring the absorption of gases. The measuring device (1) includes a radiation source (2), a first detector element (3), a second detector element (9) and a reflector array (4). The reflector array (4) defines a first optical path (5) between the radiation source (2) and the first detector element (3) and defines a second optical path (10) between the radiation source (2) and the second detector element (9). The first optical path (5) has at least two points of intersection with itself and the second detector element (9) is arranged outside of a first plane which is defined by the radiation source (2) and two points of intersection (6) of the first optical path (5).
Claims20
A measuring device for measuring the absorption of gases, the measuring device comprising:
- a radiation source;
- a first detector element;
- a second detector element;
- and
- a reflector array, the reflector array defining a first optical path between the radiation source and the first detector element and the reflector array defining a second optical path between the radiation source and the second detector element, wherein the first optical path has at least two points of intersection with itself, the second detector element is arranged outside of a plane that is defined by the radiation source and the at least two points of intersection of the first optical path.
A gas absorption measuring device comprising:
- a reflector array at least partially defining a measuring space;
- a radiation source;
- a first detector element;
- and
- a second detector element, wherein:
- the reflector array is configured in cooperation with a position of the radiation source and the first detector element to define a first optical path within the measuring space, between the radiation source and the first detector element, with the first optical path intersecting the first optical path at least at two points;
- a plane is defined by the radiation source and the at least two points of intersection;
- the reflector array is configured in cooperation with the position of the radiation source and a position of the second detector element to define a second optical path;
- the position of the second detector element is outside of the plane.
