Abstract: In implementations, an open path gas detector is disclosed that can include imaging or non-imaging optical components. The detector can include components that allow for misalignment of radiation received by the detector of about 1 without causing false alarms. In implementations, the detector can include a beam splitter or a wavelength-division multiplexing filter to allow for more of the radiation received by the detector to be detected by the sensors.

Abstract: A luminous unit for an optical gas detector, an optical gas detector including the luminous unit, and a method of recording an absorption spectrum in an optical gas detector include a light source for linearly polarised light radiation and a housing with an exit window. A wavelength of the light radiation radiated from the light source is tunable. The light source is arranged in the housing such that the main emission direction (OA) of the light source encloses an inclination angle (φ) of between 10° and 50° with a normal (N) to the main extension plane (HE) of the exit window. The direction of polarisation (P) of the light radiation encloses a rotation angle (θ) of between 22.5° and 67.5° with the plane of incidence on the exit window.

Abstract: One or more embodiments of the present invention pertain to a system, method, and apparatus that accurately measures concentration of a greenhouse gas in narrow atmospheric columns above multiple sites utilizing a network of autonomous low-cost beacons that turn on for short unannounced time intervals and point to a receiving satellite. For example, each beacon can activate for short time intervals and transmit a laser beam at eye-safe low transmission power levels to a receiving satellite. The receiving satellite includes a sensor configured to receive the laser beam from one or more activated beacon and generate raw greenhouse gas concentration data based on measurement of the received laser beam intensity at selected wavelengths.

Abstract: A gas detector includes a receiver configured to receive light from a light source through gas, the light source having a bandwidth on the order of an absorption linewidth of the gas, the receiver including at least a first etalon having a transmission bandwidth on the order of the absorption linewidth of the gas, the transmission bandwidth of the first etalon being substantially smaller than the bandwidth of the light source. The gas detector further includes a first detector for detecting light transmitted through the first etalon, a second detector for detecting light reflected from the first etalon, and a processor that determines the quantity of gas based on the detected transmitted and reflected light. The gas detector can further include a second etalon with a transmission bandwidth approximately equal and adjacent to the transmission bandwidth of the first etalon. Alternatively, the gas detector can include a beam separator that separates the light from the light source into a first beam and a second beam, with a small deflection angle between the first beam and the second beam, thereby modifying the effective thickness of a single optical element for each beam and forming the first and second etalon in the optical element.

Abstract: A light detection value determines concentration of a target component, without using a laser emitter of high laser intensity or a large light collector. By changing orientation of the laser emitter about a horizontal axis, or height of the laser emitter, a laser irradiation position on a ground or water surface is switched between first and second irradiation positions. A photodetector detects first scattered light scattering from the first laser beam at the first irradiation position, second scattered light scattering from the second laser beam at the first irradiation position, third scattered light scattering from the first laser beam at the second irradiation position, and fourth scattered light scattering from the second laser beam at the second irradiation position. A concentration calculator calculates concentration of a target component between the first and second irradiation positions, based on detection values of the first, second, third, and fourth scattered light.
