Are You Using Augmented Reality in the Design Process?

A new report concludes that the augmented reality (AR) market is expected to grow from $2.39 billion in 2016 to $61.39 billion by 2023.

World’s Brightest Laser Sparks New Behavior in Light

A rendering of how changes in an electron's motion (bottom) alter the scattering of light (top), as measured in a new experiment that scattered more than 500 photons of light from a single electron. Previous experiments had managed to scatter no more than a few photons at a time. (Credit: Donald Umstadter and Wenchao Yan)

Physicists from the University of Nebraska-Lincoln are seeing an everyday phenomenon in a new light. By focusing laser light to a brightness 1 billion times greater than the surface of the sun — the brightest light ever produced on Earth — the physicists have observed changes in a vision-enabling interaction between light and matter. Those changes yielded unique X-ray pulses with the potential to generate extremely high-resolution imagery useful for medical, engineering, scientific and security purposes.

Lindley Johnson, Planetary Defense Officer, NASA Headquarters, Washington, D. C.

NASA’s Planetary Defense Coordination Office (PDCO), managed at NASA Headquarters in Washington, D.C., is responsible for early detection of potentially hazardous objects, like asteroids and comets, and issuing warnings about their potential impacts. This requires teamwork from observatories around the world. NASA’s Planetary Defense Officer, Lindley Johnson leads the global effort to detect and follow near-earth objects

Could lenses and thick cameras become obsolete?

A team at the California Institute of Technology designed a lens-less camera. "Once scaled up, this technology can make lenses and thick cameras obsolete," said graduate student and camera researcher Behrooz Abiri. What do you think? Could lenses and thick cameras become obsolete?

Microstructural Explorations Inside Fuel Cells

Solid oxide fuel cells (SOFCs), a promising technology that can efficiently produce energy using fossil fuels with no moving parts and low emissions, present a particularly perplexing economic challenge: current systems operate at maximum efficiency between 700 and 1000 degrees Celsius, but such high temperatures shorten their service life, requiring more frequent fuel cell stack replacements. Lowering the operating temperature makes them last longer, but requires additional cells in the stack to deliver the same performance, and that drives up costs.

The Advanced Land Imager Helped NASA Mission Exceed Expectations.

After more than 16 years of operation, NASA’s Earth Observing–1 (EO-1) spacecraft was decommissioned on March 30 of this year. The Advanced Land Imager (ALI) developed by MIT Lincoln Laboratory was aboard as an alternative to the land-imaging sensor that was used by the Landsat Earth-observing program.

Robotic Vision Keeps an Assembly Plant at Home

A major manufacturer of electromechanical products had been operating six separate indexing assembly machines, each producing one of a family of more than 75 different products at about 40 parts per minute. The machines frequently sat idle as demand fluctuated for the various products. Labor expenses were high since each machine required a dedicated operator. The manufacturer considered moving the six machines and their entire production offshore to reduce labor expenses and save floor space at its European facility.

Wide-Area Surveillance Using HD LWIR Uncooled Sensors

The effectiveness of airborne search and rescue, navigation, and situational awareness tasks is predicated on the availability of high-resolution imagery that provides pilots with a clear picture and the widest possible field of view. While the human eye is extremely high resolution with an unmatched ability to detect high-spatial-frequency (HSF) objects across a wide field of regard, human vision can easily fatigue, is subject to environmental conditions, and is vastly degraded at night.

Ultra-Thin Camera Says Good-Bye to the Lens

A new proof-of-concept design retires one of the most familiar parts of a traditional camera: the lens. By swapping out the glass lens with a tiny array of light receivers, a California Institute of Technology team believes the thinner, lighter model supports a new wave of ubiquitous imaging.

DESIGNING A VISION SYSTEM: A Comprehensive Guide to the Technical Requirements for Building a Vision System for Your Unique Imaging Application

There are a number of factors that need to be considered when designing a vision system, including: the hardware platform, the operating system, the software and API, and the very things that make the vision system “see” – the camera and its lens. Although each aspect plays an important role in achieving desired results, the camera and lens are the essence of the vision system. As such, it is recommended that both the camera and the lens be selected as a pair based on overall system requirements. Here we discuss various elements of vision systems with a focus on the camera and lens.
