Abstract: An infrared detection system for seeing multiple pixel scenes and/or connecting multiple detectors, within each communications path, includes a data processor, optical toggles and/or electrical switches, and a large number of pixels and detectors. For the spatial net, the data processor sends signals to the optical toggle and electric switches connecting neighboring pixels and other detector elements to the data processor. A single communications path serves several pixels and detector elements thereby minimizing interconnection congestion from the pixels to the processing circuitry.

Abstract: A single dual mode monolithic focal plane array having an active sensor and a passive sensing capability is switched from one mode to the other by switching the bias across the cells of the array from-a passive IR mode to an-active LADAR mode, with the monolithic dual mode focal plane array having applications in missile target seekers and laser target designators. The switching is accomplished by increasing the gain of the array by as much as 30 times that associated with IR detection when laser return pulses are expected. Thus, there need be no mechanical changes to the array to afford both passive IR sensing and an active LADAR pulse detector. Nor need there be two different focal plane arrays, one for IR and one for laser radiation, which leads to boresighted alignment problems.

Abstract: Described are methods and systems for providing improved defect detection and analysis using infrared thermography. Test vectors heat features of a device under test to produce thermal characteristics useful in identifying defects. The test vectors are timed to enhance the thermal contrast between defects and the surrounding features, enabling IR imaging equipment to acquire improved thermographic images. In some embodiments, a combination of AC and DC test vectors maximize power transfer to expedite heating, and therefore testing. Mathematical transformations applied to the improved images further enhance defect detection and analysis. Some defects produce image artifacts, or nulldefect artifacts,null that obscure the defects, rendering difficult the task of defect location. Some embodiments employ defect-location algorithms that analyze defect artifacts to precisely locate corresponding defects.
