David L. ShenkenbergTo localize a tumor in the bladder, doctors routinely perform a cystoscopy, a procedure that involves inserting a lensed, lighted tube into a patient to enable their search for potentially cancerous sites. Cancer can easily be missed because doctors rely only on a narrow optical tube and their eyesight for visual analysis. Fluorescent labeling and other markers have been suggested, but these methods only stain for expected changes. Raman spectroscopy can produce a complete biochemical profile of the tissue and can be integrated into a cystoscope through fiber optics. For the initial...Read full articleRelated content from Photonics MediaARTICLES2021 Prism Awards Honor Photonics InnovationsEarlier today during the Prism Awards, SPIE, the international society for optics and photonics, and Photonics Media recognized top optics and photonics products on the market.

The layer of gases that we breathe also distorts the images formed by telescopes. This means that conventional telescopes of more than a few centimeters in diameter cannot reach the resolution limit set by their optics.To Isaac Newton the problem was clear, and in 1704 he realized the effects of atmospheric turbulence on image formation. Just as heat waves shimmering above a hot patch of ground can distort our...Photonics HandbookSWIR Imaging: An Industrial Processing Tool: Short-wave infrared (SWIR) imaging with InGaAs-based cameras is well suited to nondestructive identification of materials, their composition, coatings, and other characteristics.Imaging has long been used in industrial processes to measure, monitor, control, or otherwise manage the production of goods.
