Abstract: The present invention is directed to a method for making infrared transmitting graded index optical elements by selecting at least two different infrared-transmitting materials, each with a different refractive index, having similar thermo-viscous behavior; assembling the infrared-transmitting materials into a stack comprising one or more layers of each infrared-transmitting material resulting in the stack having a graded index profile; and forming the stack into a desired shape. Also disclosed is the related optical element made by this method.

Abstract: A method and system is provided for performing high-resolution image assembly regardless of observed scene content. An imaging system, including a focal plane array and lenslet array can be calibrated to account for subimage shifts. A calibration module can determine the subimage shifts by calculating an average point source position reference point coordinates for each of the subimages, and then determining the difference between the average point source position and the reference point coordinates for each subimage. The imaging system can then be calibrated utilizing the subimage shifts for each of the plurality of subimages. Finally, an assembly module can perform a high-resolution image assembly with the calibrated imaging system.

Abstract: The electroporation array is comprised of three technologies: microwire glass electrodes, microelectronic multiplexer stimulator chips and microfluidic flow chamber. Various substances, such as genes, gene silencing RNAi, gene inhibition agents or drugs, can be perfused into the microfluidic flow chamber. The entry of the various substances into the cells will be facilitated by electroporation. An applied electric potential causes nanoscale pores to open in the cell membrane allowing substances in the solution to freely diffuse into the cell. The specific cells selected for electroporation are defined using the computer controlled microelectronic stimulator array. An “image” of which electrodes within the array to apply the electric potential to, and thus electroporate, is de-multiplexed onto the array. All the selected electrodes deliver a current pulse varied by the intensity of the de-multiplexed “image”.

Abstract: A system for enhancing images from an electro-optic imaging sensor and for reducing the necessary focal length of a sensor while preserving system acuity. This system uniquely reduces the necessary focal length and enhances images by collecting a video sequence, estimating motion associate with this sequence, assembling video frames into composite images, and applying image restoration to restore the composite image from pixel, lens blur, and alias distortion. The invention synthetically increases the pixel density of the focal plane array. Thus it reduces the necessary size of the projected blur circle or equivalently it reduces the minimum focal length requirements.

Abstract: The retinal prosthesis test device is comprised of a thin wafer of glass made from nanochannel glass (NGC) with very small channels perpendicular to the plane of the wafer filled with an electrical conductor forming microwires. One surface of the glass is ground to a spherical shape consistent with the radius of curvature of the inside of the retina. The NGC is hybridized to a silicon de-multiplexer and a video image is serially input to a narrow, flexible micro-cable and read into a 2-D array of unit cells in a pixel-by-pixel manner which samples the analog video input and stores the value as a charge on a MOS capacitor. After all unit cells have been loaded with the pixel values for the current frame, a biphasic pulse is sent to each unit cell which modulates the pulse in proportion to the pixel value stored therein.

Abstract: An apparatus for processing imaging data in a plurality of spectral bands and fusing the data into a color image includes one or more imaging sensors and at least two image-acquiring sensor areas located on the imaging sensors. Each sensor area is sensitive to a different spectral band than at least one of the other sensor area or areas, and each sensor area will generate an image output representative of an acquired image in the spectral band to which it is sensitive. The apparatus further includes a software program that runs on a computer and executes a registration algorithm for registering the image outputs pixel-to-pixel, an algorithm to scale the images into a 24-bit true color image for display, and a color fusion algorithm for combining the image outputs into a single image.
