R. Winn HardinROSKILDE, Denmark -- A new process that impresses holographic optical elements onto polymer rolls could significantly reduce the cost of keeping roads safe at night. According to Ibsen Micro Structures developmental engineer Michael Rasmussen, street signs and reflectors embedded along roads depend on retroreflection as a passive light source. Retroreflection is the process of turning a light ray around and sending it back to its source -- in this case the headlights of an automobile. The results are highly reflective road signs, paint or clothing that keep both drivers and pedestrians safer...Read full articleRelated content from Photonics MediaArticlesTopological Cavity Widens Functionality of Surface-Emitting LasersResearchers at the Institute of Physics of the Chinese Academy of Sciences have incorporated a topological cavity into the design of a surface-emitting laser to create a device that addresses the...Photonics Spectra July 2022 IssueDark Autoionizing States Enhance EUV Laser PowerResearchers led by Tsuneyuki Ozaki and François Légaré at the Institut national de la recherche scientifique (INRS) in Quebec have developed a method that could bring extreme...Photonics Spectra July 2023 IssueNonlinear Optical Sensor Avoids Precision/Speed Trade-OffAn optical measurement method devised by a team of AMOLF researchers aims to simplify and streamline the ability to capture measurements from signals that are barely larger than the noise contained...Photonics.com 6/29/2022SPAD Elevates Spatiotemporal Resolution in Conventional MicroscopesImage scanning microscopy (ISM), a superresolution technique enabled by the advent of fast and compact detector arrays, provides signal-to-noise ratio (SNR), optical sectioning, and spatial...Photonics.com 2/23/2024Photonics Handbook ArticlesVibration Control: Limiting Mechanical NoiseIn general, there are three common approaches to reducing mechanical excitation of photonic systems.
