Abstract: A radial FPA based electro-optic imager, rather than the conventional rectilinear approach, would have basic overall system design advantages. Those system design advantages would apply to the components and the entire system implementation and include approaches to objective optical design, focal plane array FPA with fill factor, FPA layout and associated read-out integrated circuit ROIC, support electronics architecture and associated memory requirements, image processing IP algorithms, display layout and format, and eyepiece optics. A radial based approach to EO imagers would yield a device/system with attributes requiring less complicated optical components, with potentially fewer elements, for both the objective and eyepiece lenses. In addition, alternative objective optics could be more easily employed, such as holographic or wave front coded, due to reduced complexity of implementing correction algorithms as a result of referencing the system around its optical axis.

Abstract: An infrared imaging system including a substrate, a plurality of hexagonal shaped micro-bolometer pixels combined to define a focal plane array. Each pixel is electrically connected to the substrate with a pair of opposing isolation legs. One end of the isolation leg is attached to the pixel's periphery while the other is fixed to that substrate so that the focal plane array and a plane containing the substrate have a parallel, spaced-apart relationship. In this manner, the isolation legs provides an electrical communication path from each pixel to the substrate as each pixel undergoes an internal change in resistance due to absorption of infrared energy. At the same time, the legs separate the pixels from the substrate so that there is no heat transfer between the pixel and the substrate due to direct contact. The hexagonal shape arrangement also allows for a staggered arrangement of adjacent rows in the array, thereby increasing the fill factor for the focal plane array of the device.

Abstract: For a helmet-mounted imaging system to be multi-purpose, effective, lightweight, and easy to use, it must be designed with the most advanced technologies, interchangeable and expandable for future upgrades. The Interchangeable Donut Helmet concept achieves this ability through the use illustrated in FIG. 1 of Section 5. These connected modules are attached around the perimeter of the helmet. An adjustable tensioner insures compatibility and a snug fit on similar helmets (FIG. 2). Each donut module is designed for a different use such as imaging camera, battery source, global positioning, or wireless transmitter. Images are transmitted wirelessly via radio frequencies (RF) (FIG. 3). A Helmet-Mounted Display (HMD) is incorporated on the front donut module in order for the wearer to view the camera image (FIG. 4). Each donut module consists of subsystems that incorporate low cost, lightweight and low power technologies. This provides the realization of a head-borne, low power and cost effective imaging system.

Abstract: An infrared (IR) imaging system in accordance with the present invention includes a substrate, a plurality of disc-shaped microbolometer pixels that combined to define a Focal Plane Array. Each pixel is electrically connected to the substrate with a pair of opposing helical isolation legs. One end of the isolation leg is attached to the pixels periphery while the other is fixed to that substrate so that the FPA and a plane containing the substrate have a parallel, spaced-apart relationship. In this manner, the isolation leg(s) provides an electrical communication path from each pixel to the substrate as each pixel undergoes an internal change in resistance due to absorption of IR energy. At the same time, the legs separate the pixels from the substrate so that there is no heat transfer between the pixel and the substrate due to direct contact. The disc shape arrangement allows for a staggered arrangement of adjacent rows in the array, thereby increasing the fill factor for the FPA of the device.
