    Abstract: Disclosed is an instrument including a multipath, monolithic optical component, made up of a portion of a transparent material between two opposite faces of the component. One of the two faces of the component is formed by a first refracting surface, and the other face includes several second refracting surfaces which are juxtaposed. Each optical path of the component is formed by one of the second refracting surfaces in combination with a corresponding portion of the first refracting surface. One such component is suited for being part, within the instrument, of a detection module with multiple optical paths arranged in parallel, with a matrix photodetector shared by the optical paths. Such a detection module may be compact enough in order to be integrated into a cryostat cold screen, improving cooling thereof, and may be combined with an objective in order to form an instrument with multiple optical paths.

    Abstract: An optical system includes a multispectral sensor; an optical filter including a plurality of optical channels that is disposed over the multispectral sensor; and a lens that is disposed over the optical filter. The lens is configured to direct first light that originates from a scene to the optical filter. The optical filter is configured to pass one or more portions of the first light to the multispectral sensor. The multispectral sensor is configured to generate, based on the one or more portions of the first light, spectral data associated with the scene.

    Abstract: A multichannel color measurement instrument for measuring spectral properties of a target comprises pick-up optics to collect measurement light, first and second anamorphic optical paths optically coupled to the pick up optics, a pick-up polarizing element located to polarize measurement light in the second anamorphic optical path, a reference anamorphic optical path including a reference illumination source, and a two-dimensional variable filter sensor having an optically transmissive filter function that varies in a first direction parallel to a surface of the variable filter sensor and is substantially constant in a second direction parallel to a surface of the variable filter sensor and orthogonal to the first direction. The anamorphic optical paths spread the measurement light in the first direction direct it on to different portions of the variable filter sensor.

    Abstract: A radiation measuring device for measuring electromagnetic radiation originating from an external source. The radiation measuring device includes, a spectrometer, a pyranometer, a pyrgeometer, a diffuser, and a control unit. The spectrometer and a pyranometer are positioned in a sensor zone of a housing of the radiation measuring device. The spectrometer measures visible shortwave radiation and near-infrared shortwave radiation received at the sensor zone. The pyranometer measures shortwave radiation received at the sensor zone. The pyrgeometer is positioned in another sensor zone of the housing and measures longwave radiation received at the other sensor zone. The control unit receives radiation measurements from the spectrometer, pyranometer, and pyrgeometer. A corrected amount of radiation received at the sensor zones of the radiation measuring device is determined from the received radiation measurements. Other embodiments are described and claimed.

    Abstract: The present invention discloses a co-aperture multi-field of view (FOV) image-spectrum cooperative detection system, and the system includes an infrared optical window, a large FOV two-dimensional scanning mirror, a co-aperture multi-FOV main optical system, a large FOV scanning detector, a staring infrared detector, an infrared non-imaging broadband spectrum measuring unit, a data processing unit, a control unit, and a servo system. Correspondingly, the present invention further provides a method based on the system. The present invention searches a target area by using large FOV scanning, and identifies a target by using medium FOV staring infrared detection, and small FOV fine detection is finally performed on the area to identify the target in combination with spectrum data analysis. The detection sensitivity is higher, and capturing and tracking of a moving target are more precise and stable, thereby solving the technical problems that a conventional remote sensing detection cannot perform research on movement changes of a moving target and a dynamic phenomenon and searching and tracking of a small-scale object is unsuccessful; therefore, the present invention has higher implementability and practical promotion values.
