Digital Cinema Faces a Bright Future
Over the past 40 years, audiences have grown accustomed to seeing lasers used on screen in blockbuster action and science fiction films. More recently, lasers have carved out an essential role behind the scenes as well, enabling cutting-edge digital projectors that can deliver brighter images with richer color and more consistent quality over time. Digital projectors first reached theaters in 1999, with a push from George Lucas and 20th Century Fox, who wanted to use the technology to showcase the first of the modern generation of “Star Wars” films, “The Phantom Menace.” Since then, the technology has all but supplanted conventional mechanical film projection. By the end of 2017, the Motion Picture Association of America reported that 98% of the world’s cinema screens used digital projection.

Image Sensors Power Embedded Vision
New imaging applications are booming: from collaborative robots in Industry 4.0 to drones that fight fires and monitor crops, from biometric face recognition to point-of-care hand-held medical devices at home. A key enabler in the emergence of these new applications is embedded vision, which has become more accessible than ever. Embedded vision is not a new concept; it simply defines systems that include a vision setup that controls and processes data without an external computer. Embedded vision is already widely used in industrial quality control, especially in smart cameras.

Better Biomedicine via 3D Imaging
Advancements in biomedical 3D imaging promise to improve research findings and clinical outcomes, thereby producing widespread benefits. In research, a combination of techniques will enable high-speed visual 3D imaging effectively below the diffraction limit, allowing scientists to better track what goes on in the brain or to examine other tissues and organs. The results of these advancements could be discoveries about how the brain works and how diseases progress.

The New Collar Workforce
Photonics Media
U.S. manufacturing companies are expected to face a shortage of two million skilled workers by the year 2020, according to reports. As a result, manufacturers and educators are looking for real, actionable ideas to train workers, reduce the shortfall and realize the potential of the new age of manufacturing.

Low-Energy Photons Upconverted Using Nontoxic Material
Researchers at the University of California, Riverside (UC Riverside) and the University of Texas at Austin demonstrated the use of nontoxic silicon nanocrystals to convert low-energy photons into high-energy ones. The use of nontoxic materials for photon upconversion could help advance the development of photodynamic treatments for cancer.

Northwestern University researchers have developed a stereolithographic 3D printer that can print an object the size of an adult human in just a couple of hours. Called HARP for high-area rapid printing, this printer uses a patent-pending version of stereolithography that circulates liquid plastic to remove heat, which can cause printed parts to crack and deform.
