Abstract: Embodiments relate generally to electromagnetic radiation detector devices, systems, and methods using a planar Golay cell. One device includes a cell body forming a cavity therein, wherein the cavity includes a wavelength selective absorber having a predetermined absorption spectral range and the cavity is filled with a gas and a pressure sensing element fluidly connected to the cavity to measure a change in pressure within the cavity. One device may include a plurality of planar Golay cells, wherein the cell bodies of the Golay cells are stacked against one another, wherein the pressure sensing elements of the Golay cells are located adjacent to the stacked sides of the cell bodies, and wherein radiation from a single light source is directed through the plurality of Golay cells.

Abstract: Devices, methods, systems, and computer-readable media for a dual wavelength source gas sensor are described herein. One or more embodiments include a gas sensor, comprising: a dual wavelength source (102-1), (102-2) to transmit a first wavelength (104-1) within an absorption range of the gas and a second wavelength (104-2) that is outside the absorption range of the gas via an optical path, wherein a gas (106) is present through the optical path, a detector (114) to receive the first wavelength (104-1) and the second wavelength (104-2) via the optical path, and a computing device coupled to the detector (114) to determine a signal intensity for the first wavelength (104-1) and the second wavelength (104-2), wherein the second wavelength (104-2) is a reference wavelength and can be used for montoring of the laser power, for detection of the presence and/or concentration of particulate matter in the gas (106) and for identification of a system failure, such as a false alam.
