An optical ultrasound needle has been developed that allows heart tissue to be imaged in real-time during keyhole procedures. The technology was successfully used for minimally invasive heart surgery on pigs, giving a high-resolution view of soft tissues up to 2.5 cm in front of the instrument, inside the body. The all-optical ultrasound transducer, developed by a research team from University College London (UCL) and Queen Mary University of London (QMUL), uses light guided by miniature optical fibers to generate and receive ultrasound. The optical fiber is encased within a customized...Read full articleRelated content from Photonics MediaARTICLESPOC Device Pairs Optics, Ultrasound to Improve Thyroid ScreeningAn EU-funded development project for detecting thyroid cancer has produced an optical device that could give doctors a reliable, low-cost way to determine whether a thyroid nodule is malignant or...BioPhotonics Sep/Oct 2021 IssueQuantum Sensors Measure Brain Activity with Pinpoint AccuracyQuantum sensors could be used to indicate early biomarkers for brain diseases in space and time, based on the results of a University of Sussex (England) study.

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 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 HandbookInfrared Spectral Selection: It Begins with the Detector: An IR imaging system employing a narrow spectral band brings hidden images to light, broadening IR imaging’s applications.Spectral selection is a powerful tool that enhances conventional imaging tremendously.
