Hyperspectral imaging (HSI) can help surgeons make quick decisions in the operating room, as it detects issues not visible to the naked eye. Dallas surgeon Javier La Fontaine, Ph.D., associate professor of plastic surgery at the University of Texas Southwestern Medical Center, explained to a MOEMS-MEMS symposium audience at the recent Photonics West 2014 conference that using this imaging technique can reduce the threat of amputation. “It has saved some patients time spent in returns to the operating room,” he said. “It lets us more comfortably address the...Read full articleRelated content from Photonics MediaARTICLESNIR Imaging System Could ID Hard-to-Detect Cancers EarlierAn optical imaging system developed by MIT researchers could enable physicians to identify tiny tumors deep within the body, leading to earlier detection and treatment of cancer.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookMachine Vision Cameras: Making the Right Selection: Improvements and affordability have broadened the use of vision systems for inspection, but several factors should be considered before making a purchase.Technological advances have resulted in new, higher-quality sensors that enable machine vision cameras to deliver greater features and functionality at a lower cost than ever before.
