Cyclospora, an intestinal parasite, has sickened more than 22,000 Americans. The recent outbreak has been linked to contaminated lettuce from central Mexico that was later distributed in the U.S., with some researchers saying sewage contamination is the likely cause. Machine vision could prove to be vital in tracing food issues back to their original source. In this episode of All Things Photonics, BioPhotonics Senior Editor Douglas Farmer is speaking with Robb Robles, director of machine vision product management at Zebra Technologies. Robb discusses how machine vision technologies, with AI assistance, can help prevent widespread contamination of food products in the future by tracking them from the point they are harvested to when they are selected by the consumer.

Unmanned aircraft, like drones, have become a weapon of choice. They are effective and cheap to produce, but the systems to stop them are not. Laser- and microwave-based systems are slowly coming online, but there are still hurdles to overcome before they become a staple defense on the front lines. Ganesh Balakrishnan, or “Gunny" as he’s known, is a professor of electrical and computer engineering at the University of New Mexico. He sat down with the All Things Photonics team to discuss how molecular beam epitaxy, VCSELs, PCSELs, and other photonic tech all play a part in the wider ecosystem behind counter unmanned systems.

"All Things Photonics" is teaming up with the journal Optica to bring you insights on the latest studies leading to breakthroughs in optics and photonics. Quantum key distribution (QKD) allows encrypted information to be distributed without being intercepted. In free-space QKD, however, fluctuations in atmospheric conditions can cause distortions and impair the retrieval of the encoded information. In a study published in the journal Optica, a research team from the University of Ottawa developed a way to alleviate the effects of atmospheric turbulence on spatial mode transmission, creating an all-optical self-correction scheme for turbulence resilience using stimulated parametric down-conversion (StimPDC)-based optical phase conjugation. Aarón Cardoso, a researcher at the University of Ottawa, joins us to explain why he turned to StimPDC to solve this quantum quandary.

Every White House administration has its priorities. Government reform and the elimination of waste are among President Donald Trump's top priorities. Cutting down on waste is not a partisan issue; no one wants to throw away money. But how you define waste can draw a mixed response. The president has targeted scientific grants as an area in need of reform, and according to a piece published by Nature, more than 7,800 grants have been terminated or frozen. Dan Garisto is a freelance physics journalist and is one of the three authors of this piece. On this episode of All Things Photonics, he discusses the biggest findings of his work as he dug into the status of U.S. science one year into the president’s second term.
