    Abstract: A system analyzes radiation from a scene in a field of view that includes a gas cloud with absorption characteristics in a wavelength band, The system includes first and second devices. The first device includes a detector and produces pixel signals that include information associated with absorption of radiation in the gas cloud wavelength band. An image of the scene is fanned on the detector based on the pixel signals. A non-predetermined region of the scene within the field of view in which the gas cloud is present is identified based on the pixel signals. The second device includes a detector and a lens, and receives the identified region of the scene. The system determines a distance between the identified region of the scene and the system based on the lens focus relative to the identified region of the scene in an image formed on the detector by the lens.

    Abstract: Systems, methods, and devices relating to optical imaging systems for gathering data on atmospheric trace gas emissions from a satellite. An optical system used in the satellite has a Fabry-Perot interferometer coupled to a suitable telescope. The interferometer is a wide angle Fabry-Perot interferometer which creates a fringing pattern in concentric circles with each fringe being a different wavelength on the imaging system. A filter is used with the optical system and allows multiple adjacent modes in a selected spectral range to pass through the interferometer to the imaging system. Each pixel in the imaging system collects light at multiple wavelengths within the selected spectral range. The optical system gathers multiple images of the target area allowing light from the target area to be collected at multiple different wavelengths. Different absorption data for different atmospheric trace gases can be gathered in a single satellite pass over the target area.

    Abstract: A method of detecting a target gas includes the step of traversing a target area with a gas-filter correlation radiometer having a field of view oriented towards the target area. The gas-filter correlation radiometer receives reflected radiation in a passband from the target area and produces gas-filter correlation radiometer signals from the received reflected radiation. A surface reflectivity spectral profile of the target area is determined. The presence of the target gas in the target area is then determined based upon the received reflected radiation and the surface reflectivity spectral profile of the target area.

    Abstract: Radiation is received from a scene impinging on at least one focal plane. A first spectral band is sampled to obtain a first band mean signal level, and either a first band image frame is collected when the first band mean signal level is at or below a first threshold, or a first image frame is collected in a first sub-band when the first band mean signal level is above the first threshold. A second sub-band is sampled to obtain a second sub-band mean signal level and a second image frame is collected in the second sub-band when the second sub-band mean signal level is at or below a second threshold. An image to be displayed is generated by combining at least two collected frames.
