Abstract
Gas detector devices, systems, and methods using a Golay cell are described herein. One device includes a microphone having a front surface with an sound collecting aperture for receiving sound, a substrate, a gas cavity formed in the substrate such that the gas cavity is in gas communication with the sound collecting aperture and the front surface forms a side surface of the gas cavity, and a window abutting the substrate to form a side surface of the gas cavity.

A gas detector device using a Golay cell, comprising:
- a microphone having a front surface with a sound collecting aperture for receiving sound;
- a substrate;
- a gas cavity formed in the substrate such that the gas cavity is in gas communication with the sound collecting aperture and the front surface forms a side surface of the gas cavity;
- and
- a window abutting the substrate to form a side surface of the gas cavity.
A gas detecting system using a Golay cell, comprising:
- a gas detector including:
- a microphone having front surface with a sound collecting aperture for receiving sound;
- a substrate abutting the front surface of the microphone;
- a gas cavity formed in the substrate such that the gas cavity is in gas communication with the aperture;
- a window abutting the substrate forming a side surface of the gas cavity;
- an optical generation chamber;
- and
- a light source to direct light toward the gas detector.
A gas detector using a Golay cell, comprising:
- a microphone having a sound collecting aperture for receiving sound;
- a substrate having a first surface abutting the sound collecting surface and a second surface and a gas cavity formed between the first surface and the second surface of the substrate and wherein the gas cavity is in gas communication with the sound collecting aperture;
- and
- a window abutting the second surface of the substrate to seal the gas cavity.
