Finding the Right Chip-on-Tip Camera Technology

You have a great idea that could potentially revolutionize your industry: a new surgical technique, diagnostic solution, or inspection system. You already know getting there will require the latest video imaging technology from an incredibly small, sub-millimeter, package; in other words, a distal chip-on-tip (COT) video camera. The COT needs to integrate into an elegantly designed, flexible device and allow video imaging into anatomy that was previously inaccessible, or image into the tiny dark crevices of our mechanized world. The technology has to be inexpensive, yet video performance needs to be competitive with larger sensor video products with which the market is already familiar. (Figure 1). So, where do you start to identify appropriate video technologies and vendors?

New Products: March 2017 Photonics & Imaging Technology

Near Eye Displays Test System

A new test system from Gamma Scientific (San Diego, CA) offers high spatial resolution color and contrast measurements for near eye displays (NED), such as virtual reality (VR) and augmented reality (AR) headsets, and heads up displays (HUD). The Gamma Scientific NED Measurement System incorporates compact imaging optics which feed both an integrated camera viewing system and a low-noise, high-accuracy spectroradiometer.

Autonomous Driving — In a ‘Flash’

By combining CMOS technology with avalanche photodiodes, researchers at the Fraunhofer Institute for Microelectronic Circuits and Systems IMS (Duisburg, Germany) have developed a potentially cost-effective sensor prototype that aims to support driverless car applications. The “Flash LiDAR” could play a valuable role alongside the cameras, radars, and other components within autonomous vehicles.

ViDAR Optical Radar Provides New Maritime Search Capability

ViDAR, developed by Sentient Vision Systems in Melbourne Australia, provides autonomous, real-time, wide-area search capability, optically, from unmanned aerial vehicles (UAVs) or manned aircraft. ViDAR, which stands for Visual Detection and Ranging, essentially acts as an optical radar, using high-megapixel video or infrared cameras to search the ocean over significantly greater operational coverage areas than can be achieved with current optical sensor approaches.

Infrared Cameras Support Advanced 3D Printing Efforts

Additive manufacturing (AM), also known as 3D printing, is quite literally one of the most innovative technologies revolutionizing manufacturing today, in terms of both industry “buzz” and thermal properties. Unlike subtractive manufacturing methods such as machining, the growing range of AM technologies creates components directly from a computer model, adding material only where needed. Wohlers Associates, a leading independent consulting firm focused on these technologies, is forecasting that the value of the worldwide AM market will grow to more than $10.8 billion by 2021, up from just $2.2 billion in 2012. That rapid escalation, however, isn't the result of hobbyists buying desktop 3D printers that cost a few hundred dollars.

Laser Vision Helps Package Shippers See Clearly

An analyzer developed for Hubble mirror testing helps FedEx scan packages.

For more than 25 years, the Hubble Space Telescope has provided stunning photos of the universe unequalled in their depth, detail, and distinction. But in its early days, Hubble wasn't capable of sending back such breathtaking photos. Within weeks of launch, the images beamed back to Earth were fuzzy and out of focus. It was determined that Hubble's primary mirror had been ground to the wrong shape and was too flat by 2.2 micrometers, causing reflected light from the edge of the mirror to be focused on a different point than light coming from near the center. It was determined that the device used to create the nonspherical mirror had been incorrectly assembled, and the mirror's manufacturer had failed to notice the problem before Hubble was launched.

Device and Method of Scintillating Quantum Dots for Radiation Imaging

Potential applications include medical imaging and aircraft inspection.

NASA’s Langley Re search Center has developed Scintillating Quantum Dots for Imaging X-rays (SQDIX) technology that enables the creation of x-ray detectors that are more sensitive than current x-ray detectors. In addition to superior sensitivity, SQDIX also offers the promise of reducing the cost of x-ray detectors by at least a factor of 10. Simply stated, SQDIX has the potential to change the way that x-ray detection is done.
