Thermal Imaging Takes the Temperature of New Applications While thermal infrared imaging technology was once limited to defense and government-funded applications, it has become more mainstream over the past few decades. The growing awareness of the technology’s industrial benefits has primarily been driven by the increasing popularity of hand-held thermal cameras for maintenance and electrical troubleshooting. Then came the COVID-19 crisis last year,...
Freeform Micro-Optics Reel Off New Applications Much attention is given to freeform optics fabrication, which has improved the performance of traditional micro-optic imaging systems1. But replicated freeform micro-optics are also fostering...

Worsening Wildfires Spark Photonics Demand and Innovations In October 2016, a downed powerline sparked a wildfire that raged for two weeks and destroyed more than 18,000 acres in the Pike and San Isabel National Forests west of Pueblo, Colo. The so-called...
Photonics Reduces Size, Weight, and Power for Defense Systems Many modern troops go to battle carrying up to 80 lbs of gear per soldier. Approximately 20 lbs of this weight can come from batteries for radios and electro-optics. Reducing a soldier’s burden...
Editorial
Where there’s smoke, there’s photonics No silver lining will ever be enough to compensate for the lives and livelihoods lost to COVID-19. There was, however, one positive indicator for the scale of the global pandemic: Diminished travel and commute times between March and July prompted a 13% drop in fine-particle pollution compared to the same period in 2019. Pollution levels dropped again in November and December, according to...

Scientists Follow the Dots to Quantum Optical Circuits Researchers at the University of Southern California (USC) developed a method that emits uniform single photons from precisely arranged quantum dots. The advancement benefits from an existing method for intentionally arranging quantum dots that USC professor Anupam Madhukar, corresponding author on the latest study, and his team introduced nearly 30 years ago. The researchers said the development...

Inline Spectroscopy Boosts Pharmaceutical Processing and Quality Laboratory analysis of in-process pharmaceutical materials has historically included many low-value-added steps, and yet it fails to consistently prevent waste. It is also disruptive to the manufacturing process. In this conventional methodology — commonly called “quality by testing” — raw materials, intermediates, and finished products are quarantined from production, sampled, and analyzed in a...

An astronomer’s startling discovery … at the bottom of a cider can In September 2020, David Campbell, principal technical officer of astronomy at the University of Hertfordshire in England, found a discarded Kopparberg cider can atop one of the telescopes at the university’s Bayfordbury Observatory. It could have been an innocuous, if oddly placed, piece of pollution. When Campbell discovered a sheet of photographic paper inside the can, he suspected it may be...
