An imaging technique developed by researchers at the Institut national de la recherche scientifique (INRS), can measure temperature in 2D, without contact, and in real time. The method could improve photothermal therapy and help deliver early diagnoses of skin cancers. The technology — single-shot photoluminescence lifetime imaging thermometry (SPLIT) — is based on the luminescence of nanoparticles doped with rare earth ions. “These nanoparticles are considered as nanothermometers because their luminescent properties change with the temperature of the...Read full articleRelated content from Photonics MediaARTICLESNitrogen-Filled Hollow-Core Fiber Shifts Ultrafast Laser Spectra toward the InfraredResearchers from Institut National de la Recherche Scientifique (INRS) in Quebec City have introduced a method for tuning a laser’s spectrum to the infrared range.

Resolution, however, is a more complex concept.Camera resolution depends upon the optical blur diameter and the detector size. Schade combined these to create an equivalent resolution that is a function of Fλ/d where F is the focal ratio,...Photonics HandbookFluorescence Lifetime Imaging: Choosing the Best Approach: Fluorescence lifetime imaging microscopy (FLIM), which measures the spatial distribution of the fluorescence decay, can be achieved either in the time or in the frequency domain. Each approach exhibits advantages and disadvantages, depending on the type of light detector and acquisition method employed.The term fluorescence is often applied as a synonym for photoluminescence, although luminescence actually covers fluorescence and phosphorescence. Both of these terms describe the process of...Photonics HandbookHyperspectral Imaging Spectroscopy: A Look at Real-Life Applications: Spectral imaging has grown from an expensive research-oriented technique to one that is applicable for a wide range of scientific and industrial applications.
