A spacecraft telescope door (10) adapted for use with remote sensing devices requiring optical and infrared calibration. The door (10) includes a first calibration surface (24) disposed on a first panel (14) for providing a radiant temperature reference for infrared calibrations. A second calibration surface (26) is disposed on a second panel (12) for providing an absolute radiance reference for optical calibrations. A panel hinge (16) controls the relative position of the panels (12,14) with respect to each other, and an aperture hinge (20) controls the relative position of the panels with respect to the aperture (28). In a specific embodiment, the first surface (24) is painted with chemglaze Z306, a highly emissive paint with a low reflectance for facilitating infrared calibration. The second surface (26) is painted with YB71, a diffuse reflective paint for facilitating optical calibration. In the illustrative embodiment, the panel hinge (16) and the aperture hinge (20) are motorized for controlling the relative orientation of the panels (12,14) and the aperture (28).

An image intensifier tube comprising a sealed envelope having therein means for controllably liberating oxygen within the envelope, and an input screen including an oxygen conditioned layer of fluorescent material and an overlying layer of photoemissive material which may be oxidized to improve the photon-to-electron conversion efficiency of the input screen. A method of improving the conversion efficiency of an image intensifier tube input screen including the steps of exposing a layer of fluorescent material to oxygen prior to the deposition of an overlying layer of photoemissive material, and subsequently exposing the layer of photoemissive material to oxygen, if desired, after the tube envelope has been sealed.

A focal plane array employing a segmented multiplexer having differing unit cell capacitances and amplifiers in respective segments of the multiplexer. The segmented multiplexer accommodates and processes the maximum expected signal at differing illumination levels without saturation and provides for optimized noise levels in each of its segments. The focal plane array includes an array of detectors and an array of multiplexer cells respectively coupled thereto. The array of detectors comprises a plurality of groups of detector elements that each detect energy in a predetermined spectral region. The array of multiplexer cells comprise a plurality of groups of multiplexer cells that are respectively coupled to the plurality of groups of detector elements. Each multiplexer cell includes an integrating capacitor and an amplifier, and the integrating capacitor of each cell in a particular group has a predetermined capacitance whose charge integration capability corresponds to an expected maximum intensity level of radiation in the particular spectral region that is detected by the corresponding detector element in the detector array. The optimization of the characteristics of the integrating capacitor and amplifier provided for optimized detection of the radiation in that spectral region.

An imaging device and method of imaging an object is disclosed. The device includes a two-dimensional focal plane including a plurality of rows of pixels. The pixel is configured to measure an intensity of light directed onto the pixel using a gain parameter. A gain adjuster adjusts the gain parameter for a selected row of pixels of the focal plane array independently of a gain parameter of another row of pixels.
