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 MediaArticles3D Printing Tackles One of the Strongest Stainless SteelsA team from the National Institute of Standards and Technology (NIST), the University of Wisconsin-Madison (UW-Madison), and Argonne National Laboratory have 3D-printed a variety of stainless steel...Photonics.com 9/26/2022Quantum-Assisted Coating Could Cool Indoor Spaces Without Using EnergyTo cool buildings more efficiently, researchers at the University of Notre Dame and Kyung Hee University in South Korea developed a high-performance, transparent radiative cooler (TRC) using quantum...Photonics Spectra February 2023 IssueModified Raman Microscopy Technique Reveals Molecular Orientation PatternsResearchers at the National Institute of Standards and Technology (NIST) have developed a way to measure the 3D orientation of molecules within a material made of polymers.
