摘要： A color preserving image intensifier having synchronously reciprocating input and output multi-segmented, multi-color filter slides. To compensate for differences in exposure time of the segments of the filters arising from varying reciprocation velocity due, e.g. to sinusoidal motion, either the intensity of the output image is variably filtered or the intensifier gain is varied. In one embodiment, polarizing filters rotated in synchronicity with the reciprocation of the color preserving filters vary image intensity. In another embodiment, intensifier gain is varied based upon a velocity indicator.

摘要： A method for fabricating a stripe color filter for the input of an image intensifier having a color-interpretive CCD output includes ascertaining CCD subpixel-to input coordinate correlation by test illumination with a positioning laser having low power. Based upon the correlation data assembled, light sensitive filter media, such as color tinted photoresist is exposed at those locations corresponding to like-color CCD subpixels. The media is then developed to form filter media. Subsequent coatings of photoresist of the next color are applied and exposed etc.

摘要： A differential electronic imaging system has a diode array camera and a plurality of A/D processing circuits connected to the respective diode pixel elements in parallel. The A/D processing circuits are operated in successive frame periods including a first partial period for processing an object-plus-FBP image and a second partial period for processing a fixed background pattern (FBP) image, in order to derive digital differential image data representing the object image alone. The use of parallel processing eliminates the bottleneck of conventional serial processing of the pixels of the image plane, and permits better sensitivity and image resolution. The use of the A/D processing circuits for direct conversion of the object-plus-FBP image minus the FBP image in each frame period eliminates readout noise, high frequency noise errors, FBP drift errors, and storage requirements for the FBP image. Other features include a chopper section synchronized to the clock cycle for each frame period, which also selectively controls a laser source for applications of the system as a target locator.

摘要： A color image intensifier device combines an image intensifier tube providing monochrome output with input and output color members each having a plurality of color portions for passing respective different light frequencies. The input color member filters the incoming light to the tube for each light spectrum band in timed succession, and the monochrome output of the tube passes through the output color menber to produce a corresponding color component output. The color component outputs are perceived by the eye as a complete color image if the timed modulation of the incoming image is above the threshold level for flicker. In a mechanical version, the color members are input and output color wheels rotated in tandem at the input and output ends of the image intensifier tube. The filter members may also be arranged in the form of linearly reciprocating slides or planes movable in two dimensions. The color members can also be stationary filters which change color by electronic control. The color members may have different input and output filter portions for assigning a false color to a selected input light band, such as infrared light.

摘要： A fiber optic viewing device has in a first embodiment, a color-preserving image intensifier positioned at the viewing end thereof. In a second embodiment, an input light source is sequentially modulated through a cycle of wavelength sets. The resulting image is intensified and recolored by an output recoloring filter which is synchronized with the input light modulation. In yet another embodiment, a set of red, green and blue LEDs are sequentially modulated by a controller to provide input light. A CCD camera receives the resultant intensified image and converts it to video format. A video processor stores frames during a cycle of modulation and then integrates the frames for viewing in full color.
