Abstract:Spectral imaging is a critical surveillance technique for recognition of underwater objects such as submarines because they leave unique spectral signatures as greenish chemiluminescent trails. These are created by small ocean animals (e.g., fish, eels, squid, worms) under stress, and may remain for… more

Abstract:Physical Optics Corporation proposes an all optical means for detecting and locating the position of arcing in high power microwave waveguides. When a high-power waveguide is installed in a corrosive environment, joints in the waveguide often deteriorate and gaps develop that lead to arcing and to… more
Abstract:The fundamental bottleneck in existing Focal Plan Arrays (FPAs) is that they are able to provide fast and information-lossless data transfer between the FPA and the a massively parallel processor.

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
