University of Illinois researchers have a new low-cost method to carve delicate features onto semiconductor wafers using light – and watch as it happens. The team’s new technique can monitor a semiconductor’s surface as it is etched, in real time, with nanometer resolution. It uses...

The microgravity conditions of space travel result in unique physiological demands on the human body. In particular, the absence of the continual mechanical stresses on the skeletal system that are present on Earth cause the bones to decalcify. Trabecular structure decreases in thickness...

By modifying the rate at which chemical reactions take place, nanoparticle catalysts fulfill myriad roles in industry, the biomedical arena, and everyday life. They may be used for the production of polymers and biofuels, improving pollution and emission control devices,...

Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have created an ultrathin, flat lens that focuses light without imparting the distortions of conventional lenses. At 60 nanometers thick, the flat lens is essentially two-dimensional, yet its focusing power...

Using smartphones' GPS and imaging capabilities, University of Missouri researchers have developed new software that determines the exact location of distant objects, as well as monitors the speed and direction of moving objects. The software could eventually allow smartphone-armed soldiers...

PML researchers have devised a novel source of portable sunlight that may fill an urgent need in renewable energy research – namely, light sources that generate a near-perfect solar spectrum to be used in testing the performance and efficiency of photovoltaic (PV) materials.The team’s...

Current transcranial color Doppler (TCD) transducer probes are bulky and difficult to move in tiny increments to search and optimize TCD signals. This invention provides miniature motions of a TCD transducer probe to optimize TCD signals.

The key advantages of this approach include the fact that the index of interface glass (such as Pb glass n = 1.66) greatly reduces Fresnel losses at the fiber-to-waveguide interface, resulting in lower optical losses. A contiguous structure cannot be misaligned and readily...

The General MACOS Interface (GMI) for Modeling and Analysis for Controlled Optical Systems (MACOS) enables the use of MATLAB as a front-end for JPL’s critical optical modeling package, MACOS. MACOS is JPL’s in-house optical modeling software, which has proven to be...

The objective of this work was to develop a new class of readout integrated circuit (ROIC) arrays to be operated with Geiger avalanche photodiode (GPD) arrays, by integrating multiple functions at the pixel level (smart-pixel or active pixel technology) in 250-nm CMOS...

Teledyne DALSA (Billerica, MA) has expanded its Genie™ TS camera series with the addition of three color models that use CMOS imaging sensor technology. The Genie TS color cameras, which include 5M, 8M, and 12M models, reach speeds up to 29 fps.
