摘要： A heterodyne starring array active imager for producing an image. The imager comprises a light source intermittently illuminating a scene and an array of light collecting sites imaging the scene, each one comprising: a coupling component optically coupling scene light into a first waveguide and a local oscillator light coupled into a second waveguide. The first and second waveguides coupled to a third waveguide such that the scene light and local oscillator light propagate into the third waveguide. A square law photo detector associated with each light collecting site receives the merged light for heterodyning the scene light and the local oscillator light. Components receive and process the heterodyned light from the photo detectors to produce a frame signal for each light collecting site. A read-out device produces an array signal responsive to the frame signal from each light collecting site.

摘要： This Orthogonal Code Readout (OCR) electronically expands the dynamic range of CMOS active pixels by adding digital electron wells. The dynamic range of an active pixel is not limited by in-pixel capacitance. When employed as a thermal array readout, OCR simplifies thermal detector array fabrication by eliminating the need for large electron well capacitors. OCR also improves digital quantization beyond that provided by hardware digitizers.

摘要： A system for fusing a direct image and a reflective image. The system comprises a first image sensor sensing the direct image from a scene where the direct image comprises direct image pixels. A second image sensor senses the reflective image from the scene where the reflective image comprising reflective image pixels. A component spatially registers the direct image pixels and the reflective image pixels. A digital processor fuses an intensity value of each direct image pixel and an intensity value of an aligned or registered reflective image pixel to generate a fused pixel value, where a plurality of fused pixel values forms a fused image that is displayed on a monitor.

摘要： A method for generating a color image. The method comprises collecting a color image of a scene, the color image comprising three color slice images, each one comprising color image pixels, and collecting an achromatic image of the scene, the achromatic image comprising achromatic image pixels. The achromatic image having a higher resolution than the color image. The achromatic image is presented on a first screen comprising a white phosphor. The color slice images are processed to reduce noise, to increase a signal-to-noise ratio, to increase contrast, and/or to normalize the pixel intensity values in each color slice. The color image is presented on a semi-transparent screen or display. The semi-transparent screen is situated between an observer and the achromatic image on the first screen. An optical component is used to view an image on the first screen through the semi-transparent second screen.

摘要： Methods for design and production of highly sensitive active and passive light detecting devices and systems. Orders of magnitude improvement in optical signal detection is made possible in high noise or low contrast scenes. The current invention creates a small spectral difference between two parts of a split light stream. When recombined, the altered light streams partially correlate, and that generates full amplitude signal oscillation at a frequency that depends on the constituent spectrum. The full amplitude signals and spectrum dependent oscillation make signal discrimination much better than intensity-only methods. The effect of read noise, amplifier noise, dark current noise, and thermal noise due to photo detector shunt resistance, become less important when compared to light detection using prior art methods

摘要： A heterodyne starring array active imager for producing an image. The imager comprises a light source and a component for segregating the light into frequency bands, each band intermittently illuminating a region of a scene and an array of light collecting sites, each comprising: a coupling component optically coupling scene light into a first waveguide and a local oscillator light coupled into a second waveguide. First and second waveguides coupled to a third waveguide with scene light and local oscillator light propagating into the third waveguide. A square law photo detector at each light collecting site receives the merged light for heterodyning the scene light and the local oscillator light. Components receive and process the heterodyned light from the photo detectors to produce a frame signal for each light collecting site. A read-out device produces an array signal responsive to the frame signal from each light collecting site.

摘要： A system for creating and displaying a color image having a higher resolution than a source color image. The system comprising a first sensor for sensing electromagnetic energy in a first spectral band to generate an achromatic image of achromatic image pixels. A second sensor for sensing electromagnetic energy in a second spectral band to generate a color image comprising a triad of color pixels. A digital processor interpolates the color triad pixels to achieve a count of color triad pixels equal to a count of achromatic image pixels. The digital processor fuses each color triad pixel, pixel by pixel, with an achromatic image pixel to produce fused color pixels. A display responsive to the fused color pixels displays a color image of the scene.
