Abstract
Official abstract text for this publication.
A radial based approach to electro-optic imagers, 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. The radial readout EO system would have pixel ‘one’ at the center and be ‘read out and displayed’ like the rings of a tree rather than words on a page.
First claim
Opening claim text (preview).
What is claimed is: 1. A radial readout process for an electro-optic imager, the process comprising: projecting an object in image space onto an objective lens assembly, which focuses an image of said object onto a radial sensor FPA, wherein said radial sensor FPA has concentric rings of pixels sequenced from a center; reading out signals from said radial sensor FPA using a readout integrated circuit to process signals with support electronics and display drivers having a reduce…
