Abstract: A thermal imaging apparatus comprises a housing defining an entrance pupil for ingress of imaging radiation. At least one light sensor is positioned forward of the entrance pupil. An electronic imaging device such as a focal plane array is located in the housing rearward of the entrance pupil for converting imaging radiation to electrical signals for further processing. The apparatus further includes a shutter having an open position and a closed position. In the closed position, the shutter is located between the entrance pupil and the electronic imaging device so as to inhibit exposure of the electronic imaging device to incident radiation. Circuitry is provided for selectively operating the shutter to be in the closed position based on signals produced at the light sensor.

Abstract: In an infrared detector package, a first annular metallized layer (6a, 6b) is formed along the annular shoulder (4a) of a casing member (4), and a second annular metallized layer (7) is formed along the annular mating surface of a window member (5). Brazing material (8) is integrally interposed between the first and second metallized layers. At least one of the first and second annular metallized layers comprises a mutually separated concentric portions (6a, 6b), and the brazing material extends across the two mutually separated concentric portions. During the manufacturing process, brazing material is deposited on one of the two mutually separated concentric portions, and is allowed to flow along the opposing metallized surface until the brazing material reaches the other of the two mutually separated concentric portions. Because the brazing material exposes a clean metallic surface as it flows so that the brazing material is properly interposed between the opposing annular metallized layer and the other of the mutually separated concentric portions of the corresponding annular metallized layer without any intervention of dross, oxidized film or other foreign matters. Thereby the brazing material ensures a favorable bonding and sealing performance.

Abstract: Variable aperture and actuator assemblies are provided for a radiation detector housing in an imaging system. The variable aperture assembly includes a ring mounted over the housing's window, a plate having a first aperture disposed over the window, an aperture blade operatively coupled to the ring so the blade moves laterally relative to the first aperture, and an aperture drive mechanism having a body and an actuator coupling member extending at an angle from the body. The drive mechanism is adapted to drive the blade laterally away from the first aperture when the member is moved in a first lateral direction, and over the first aperture to define a second aperture disposed over the window when the member is moved in a second lateral direction. The actuator assembly has an actuator and an actuator arm adapted to engage the actuator coupling member to control the lateral movement of the member.

Abstract: The present invention is directed to a method and apparatus for reducing the effects of window clouding on a viewport window in a reactive environment. One or more clouded viewport windows are obtained for testing, in which the clouding results from exposure to the reactive environment. The clouding typically appears as a coating film on the test windows. The clouded viewport windows are analyzed for one or more spectral regions having good transmission. The threshold level of light transmission is determined by the particular application in which the window is used. The spectral regions of good transmission are evaluated for their usefulness with a particular algorithm that will use the spectral data in a production environment. Spectral regions that cannot be evaluated using the subject algorithm are eliminated from consideration. Spectral regions that can be evaluated using the subject algorithm and exhibit low absorption are selected for monitoring in the production environment.

Abstract: Remote sensing in an environment having temperatures greater than 300° C., using an optical fiber having a core (10), a cladding (20), and a metallic protective coating (30) on the cladding to protect a surface of the cladding, the cladding having a diameter greater than 150 μm, and a thickness of at least 50 μm. The larger diameter cladding means stress from the metallic protective layer can be reduced, giving lower optical loss and better hydrogen protection. A metal conduit (330) encapsulates the sensing fiber, and a pump evacuates the conduit to reduce hydrogen seepage. Ceramic splice protectors are used. OTDR is used to determine differential loss at different locations along the fiber. A reflective element at the far-end of the fiber eases calibration.
