摘要： The disclosed system and apparatus for a sensor support structure generally includes a substantially reflective support strut having discontinuous protrusions on the support surface presented to the field of view of the sensor. These discontinuous protrusions may be suitably configured such that ambient thermal radiation is generally reflected away from the support strut and divergent from acceptance in the sensor's optical train.

摘要： A device for measuring a temperature of an exhaust gas flow in an exhaust branch of an exhaust gas section of an internal combustion engine is disclosed. A sub-region of the exhaust branch is configured as a parabolic mirror having a focal point positioned outside of the exhaust branch. The device includes a side channel member attached to the exhaust branch and having an open end adjacent to the exhaust branch and a closed end; and a radiation sensitive sensor disposed in the side channel member and at the focal point. The open end is in fluid communication with an interior of the exhaust branch through a cutout of the exhaust branch so that the sensor is coupled to radiation of the exhaust gas flow for measuring a temperature of the exhaust gas flow. A related method is also disclosed.

摘要： A lightweight camera is provided that includes a lightweight lens system that has a reduced number of lenses. Reducing the number of lenses produces a lighter camera, but produces a distorted local image. The distorted local image is captured by the lightweight camera, and is preferably transmitted to a remote station. The remote station then performs image processing on the distorted image to remove at least some of the distortion in the image. Preferably, a Massively Parallel Richardson-Lucy (MPRL) algorithm is used to identify and remove distortion from the image. Also, motion, temperature and inter-detector difference distortion is detected and corrected.

摘要： A device comprising a fiber grating loop ringdown (FGLRD) system of analysis is disclosed. A fiber Bragg grating (FBG) or Long-Period grating (LPG) written in a section of single mode fused silica fiber is incorporated into a fiber loop. By utilizing the wing areas of the gratings' bandwidth as a wavelength dependent attenuator of the light transmission, a fiber grating loop ringdown concept is formed. One aspect of the present invention is temperature sensing, which has been demonstrated using the disclosed device. Temperature measurements in the areas of accuracy, stability, high temperature, and dynamic range are also described.

摘要： A compact, wide field of view, infrared imaging system with two Mid-Wave Infrared (MWIR) and, optionally, an additional one Long-Wave Infrared (LWIR) band, has a single, color corrected lens element embedded within the detector/dewar assembly. The lens element has two aspherical surface profiles and utilizes a holographic optical element to manipulate and detect bands of energy that are harmonic components of each other. The infrared imaging system simplifies and shrinks the MWIR/LWIR imager while maintaining all of the required functionality. An exemplary infrared imaging apparatus performs at an F-stop (F/#) of at least 1.4 with a square field of view of 90×90 degrees.

摘要： Sensing in an elevated-temperature environment is provided using a sensor system having a sensor housing with an exterior wall with a window-support region having an outwardly facing external face, and a window through the window-support region of the exterior wall and affixed to the exterior wall. A sensor unit contained within the sensor housing receives an input signal through the window. A thermal-insulation layer is on the external face of the window-support region of the exterior wall at a location immediately adjacent to the window. The sensor system is operated in an environment wherein the window-support region of the exterior wall is heated to a temperature of greater than about 100null C. in the event that no thermal-insulation layer is present. In a typical application, the sensor system is attached to an aircraft such that the external face is in a forward-facing orientation, and the aircraft is operated such that the external face is heated by aerodynamic heating.

摘要： A wide-angle IR imaging system (1A) has an entrance aperture (40) for admitting IR from a scene and a dewar (4A) that contains a coldshield (3) that encloses a cooled IR detector (2) disposed at an image plane (2A). The dewar includes a dewar window (4), and an optical axis of the IR imaging system passes through the dewar window and the image plane. The IR imaging system further includes a plurality of uncooled optical elements (22, 24, 26, 28) disposed along the optical axis between the entrance aperture and the dewar window, and a plurality of generally annular reflector segments (18A, 18B) disposed around the optical axis between the dewar window and the entrance aperture. Each of the reflector segments has a reflective surface that faces the dewar window. An opening through an outermost reflector segment furthest from the dewar window defines an effective cooled aperture stop, or warm stop (20A) of the IR imaging system, and at least one of the optical elements (22) is disposed between the effective cooled aperture stop and another one of the reflector segments (18A) that is located nearer to the dewar window. In the preferred embodiment the at least one optical element, and the reflector segment that is located nearer to the dewar window, are comprised of a single monolithic body (31) that has a compound optical surface.
