GRENOBLE, France, Feb. 11, 2019 — CEA-Leti, a French research institute for electronics and information technologies, has developed a novel retinal-projection concept for augmented reality (AR) uses based on a combination of integrated optics and holography. The lens-free optical system uses disruptive technologies to overcome the limitations of existing AR glasses such as limited field-of-view and bulky optical systems. In typical AR glasses, images are transmitted close to the eyes by a microdisplay that includes an optical system and an optical combiner. The microdisplays create a small near-to-eye image, which is...Read full articleRelated content from Photonics MediaARTICLESSeeing Red: InGaN Microdisplay Sharpens AR GlassesA microdisplay developed by University of Cambridge spinout Porotech is expected to accelerate the development and commercialization of augmented reality glasses.

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 HandbookCamera Resolution: Combining Detector and Optics Performance: Most image-quality discussions center on resolution, which is thought to uniquely determine system performance. Resolution, however, is a more complex concept.Camera resolution depends upon the optical blur diameter and the detector size.
