Abstract: Disclosed is an optical device for deflecting a light beam, including: —a first flat reflective element arranged so as to reflect an incoming light beam into a reflected light beam, extending in a first plane, the incoming light beam and the reflected light beam defining an incidence plane; and —a second flat reflective element, arranged to reflect the reflected light beam into an outgoing light beam, extending in a second plane that is transverse to the plane of incidence. The first plane and the second plane are secant along a line of intersection and form between them a dihedral angle. The first reflective element and the second reflective element can be rotated together about an axis of rotation substantially coincident with the line of intersection.

Abstract: An optical system includes an optical element and an optical filter with a first set of channels and a second set of channels respectively associated with a first region and a second region of the optical filter. The optical element causes first light beams and second light beams associated with a subject to respectively fall incident on the first region within a first incidence angle range and on the second region within a second incidence angle range. A first channel, of the first set of channels, passes, based on the first incidence angle range, a set of the first light beams that are associated with a first subrange of a particular wavelength range. A second channel, of the second set of channels, passes, based on the second incidence angle range, a set of the second light beams that are associated with a second subrange of the particular wavelength range.

Abstract: A low cost, low power, passive optical methane monitoring system for fixed-position installation at oil and gas production well pads and gathering centers is disclosed. The optical methane monitoring system disclosed can be a scannable field of view Near Infrared (NIR) filter photometer to detect and quantify methane concentration in a two dimensional or a three dimensional grid above and around a facility. A randomized fiber optic bundle is disclosed that can be used to direct the total optical power from a collection lens to two or more isolated optical channels. Band pass filters isolate a desired wavelength range for transmission measurements for the two or more channels. Also disclosed is an absorption algorithm which accounts for variable background spectral intensity as well as correcting for water vapor and overall scattering effects to measure methane concentration for a given field of view.

Abstract: A high-speed and high-accuracy spectral video system has a filter module that filters optical signals in desired bands; a beam splitting module that splits the signal from the filter module into two identical beams entering an encoding aperture module and an RGB information acquisition module, respectively; a dispersion module disperses the optical signal and transmits the dispersed signal to a grayscale information acquisition module; a data reconstruction module aligns the signal from the grayscale information acquisition module to the signal from the RGB information acquisition module, denoises the signals, reconstructs a video by a bilateral filtering algorithm, and sends the reconstructed video to a display module for storage and display. A flame spectrum can be reconstructed using few sampling points to obtain broad-band spectral characteristics of the flame or using many sampling points to obtain high-accuracy spectral data.
