Abstract
A system includes a sensor body that has a folded optical waveguide configured in a “U” shape, wherein the waveguide is configured to convey infrared energy from one end of the waveguide to the other end of the waveguide.
Claims25
A sensor, comprising:
- a sensor body having a first end and an opposing second end;
- a folded optical waveguide positioned within the sensor body and configured in a “U” shape having a first section, a second section, and an intermediate portion joining the first section and the second section, wherein the waveguide is con d to convey infrared energy from a first end of the waveguide to a second end of the waveguide, and
- wherein the second section of the waveguide is tapered along its entire length extending between the first end of sensor body and the opposing second end of the sensor body.
A sensor comprising:
- a sensor body having a first end and an opposing second end, comprising:
- a top-portion, comprising a first recess;
- a bottom-portion, comprising a second recess configured to mate with the first recess;
- at least one cavity providing an aperture between an outside surface of the sensor body to the first recess, to the second recess, or both;
- an infrared source inlet configured to receive an infrared source;
- and
- an infrared detector inlet configured to receive an infrared detector;
- an infrared source disposed in the infrared source inlet of the sensor body;
- an infrared detector disposed in the infrared detector inlet of the sensor body;
- wherein, when mated, the first recess and the second recess form a waveguide configured to carry energy emitted from die infrared source to the infrared detector, the waveguide having a first section, a second section, and an intermediate section joining the first section and the second section, and
- wherein the second section of the waveguide is tapered along its entire length extending between the first end of the sensor body and the opposing second end of the sensor body.

A sensor, comprising:
- a folded optical waveguide configured in a “U” shape having a first section having an infrared source end and a second end, an intermediate portion having a first end and a second end, a second section having a first end and an infrared detector end, the second section being tapered entirely between its first end and its infrared detector end,
- wherein the second end of the first section is in contact with the first end of the intermediate portion and the first end of the second section is in contact with the second end of the intermediate portion,
- wherein the waveguide is configured to convey infrared energy from the infrared source end of the first section to the infrared detector end of the second section.
