WUHAN, China, Jan. 7, 2022 — Although reflective-detected laser speckle contrast imaging (LSCI) is a powerful tool for monitoring blood flow circulation at the surface layers of tissue, it is inadequate for detecting signals from thick tissue layers. A scientific team from Huazhong University of Science and Technology explored the capability of transmissive-detected LSCI (TR-LSCI), an alternative approach to monitoring blood flow in thick tissue. Using TR-LSCI, the researchers were able to obtain a strong signal-to-background ratio (SBR) for deep signals that were barely detectable using windowless LSCI in the...Read full articleRelated content from Photonics MediaARTICLESLaser Speckle Method Captures Blood Flow in MicrovasculatureResearchers at the National University of Singapore developed a confocal laser speckle autocorrelation method to image dynamic flow in microvasculature.

For example,...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 HandbookWhat Is Photonics?: An overview and brief history of photonics technology and its applicationsPhotonics is the study of light and other types of radiant energy whose quantum unit is the photon.
