Abstract:There is a need for developing a high-performance single photon avalanche photodiode (SPAD) detector array design, which can be fabricated using a domestic, high-volume commercial CMOS process on 200mm or greater wafers. Many of todays silicon photomultiplier (SiPM) devices are fabricated using… more
Abstract:Silicon photomultipliers (SiPMs) have recently gained considerable interest as replacements for photomultiplier tubes. Like photomultiplier tubes, they are capable of measuring extremely low light levels, to the point of being able to detect single photons. However, compared to photomultiplier tubes… more
Abstract:Electricity generation processes burn fossil fuels, generating heat that is then used to produce power in a series of efficiency-robbing mechanical steps. These processes are able to generate a large amount of power, but waste a staggering 50 to 60% of the available heat energy due to technology… more
Abstract:Planned science instruments require timeofflight (TOF) detectors with subpicosecond resolution, high count rates, and a large number (hundreds of thousands) of parallel channels. Timetodigital converters (TDCs) are effective for TOF measurement. With few exceptions, subnanosecond TDCs have been… more
Abstract:CMOS APS detectors have emerged as an attractive imaging solution to replace CCD technology. They can be very thin, yield good signaltonoise ratio (SNR) at room temperature, and offer the possibility of incorporating inpixel data processing. But despite its potential, APS has demonstrated relatively… more
Abstract:Domestic CMOS imager manufacturing technologies are attractive as a replacement for CCDs but do not yet meet all the requirements of scientific imagers. Their use in tailored scientific imaging applications is hampered by the large wafer sizes and high cost of deepsubmicron fabrication; the low… more
Abstract:To fully utilize thirdgeneration synchrotron sources, the Xray science community needs advanced detectors that are tailored to beamline science. Detectors are not yet available for the fastest bunch modes, and at the fastest operating modes, collection of multiple bunches is required, laser energy… more
Abstract:Flatpanel Xray detector technologies are desired to replace Xray film, but available detector materials have a number of limitations, such as low efficiency, low sensitivity, high noise, small format, high cost, long product development times, and/or expensive infrastructure. Directdetection… more
Abstract:ABSTRACT: Nanocrystals (NCs) offer many potential benefits for optical refrigeration; these quantum-confined materials have discrete energy levels, large optical transition dipole moments, and high photoluminescence quantum efficiency.

Abstract:A flash LADAR camera will be designed and demonstrated in the Phase I program. After fabricating a series of high-gain, low-excess-noise, back-illuminated avalanche photodiode (APD) arrays, including 88, 3232, 128128, and 256256 formats, the arrays will be hybridized to one or more existing flash… more
Abstract:The most effective strategy to increase LADAR range performance while minimizing size, weight and power (SWAP) growth is to increase the sensitivity of the detectors used in the receiver. To address this need, a radiation-hard, 256256-format flash-LADAR receiver will be developed based on… more
Abstract:Advances in component technologies have enabled new classes of coherent LADAR systems that offer the potential for enhanced persistent space surveillance and asset protection. Their complex-valued images allow for imaging functions not possible with intensity-only images, including coherent… more
Abstract:The persistent surveillance infrared imaging systems deployed on USAF air- and space-borne platforms typically employ staring focal plane array (FPA) technology, which despite their large formats, have insufficient pixel bandwidth and frame rates to characterize small, energetic, fast-moving objects… more
Abstract:ABSTRACT: Tagging, Tracking, and Locating (TTL) using optical taggants is a powerful tool for locating modern military threats. While many taggant delivery systems have been conceived, few are practical. Large surface-to-volume ratios make nanoparticles difficult to work with as they tend to… more

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.
