Cameras

Researchers from the Georgia Institute of Technology and Penn State University have developed an automated imaging technique for measuring and analyzing the root systems of mature plants. The technique, believed to be the first of its kind, uses advanced computer technology to analyze...

Researchers at the University of Granada have designed a new imaging system capable of obtaining up to twelve times more color information than the human eye and conventional cameras, which implies a total of 36 color channels. The important scientific development will facilitate the easy...

By the end of September, NASA aerospace engineer Jason Budinoff is expected to complete the first imaging telescopes ever assembled almost exclusively from 3D-manufactured components.Under his multi-pronged project, funded by Goddard’s Internal Research and Development (IRAD) program,...

Researchers at MIT, Microsoft, and Adobe have developed an algorithm that can reconstruct an audio signal by analyzing minute vibrations of objects depicted in video. In one set of experiments, the team was able to recover intelligible speech from the vibrations of a potato-chip bag photographed...

Three bowling ball-size free-flying Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) have been flying inside the International Space Station since 2006. These satellites provide a test bed for development and research, each having its own power, propulsion,...

A heat-sensing camera designed at Arizona State University has provided data to create the most detailed global map yet made of Martian surface properties.The map uses data from the Thermal Emission Imaging System (THEMIS), a nine-band visual and infrared camera on NASA’s Mars Odyssey orbiter. A...

Researchers at MIT and Cornell University will provide photographers with squadrons of small, light-equipped autonomous robots that automatically assume the right positions for photographic lighting. With the new system, the photographer indicates the direction from which the rim light should...

A handheld radiation camera developed by University of Michigan engineering researchers offers nuclear plant operators a faster way to find potentially dangerous hot spots and leaky fuel rods.The new 'Polaris-H' detector lays a gamma-ray map over an image of a room, pinpointing radiation sources with...

The SPIE Defense Security & Sensing Show in Baltimore, which began on Monday and ends today, provided attendees with an exhibit hall full of new products and technologies. If you weren’t at the show, here’s some of what you missed:

Eight billion years ago, rays of light from distant galaxies began their long journey to Earth. That ancient starlight has now found its way to a mountaintop in Chile, where the newly constructed Dark Energy Camera, the most powerful sky-mapping machine ever created, has...

What happens when you put a fully equipped five-story building — which includes an intensive care unit, a surgery suite, piping and air conditioning, fire barriers, and even a working elevator — through a series of high-intensity earthquakes?

Theodolites are a common instrument in the testing, alignment, and building of various systems ranging from a single optical component to an entire instrument. They provide a precise way to measure horizontal and vertical angles. They can be used to align multiple objects in a desired way...
