JAKE SALTZMAN, NEWS EDITOR [email protected]A material developed and introduced by researchers at the University of Luxembourg will help robots analyze and understand their surroundings. The material relies on retroreflective spheres made from cholesteric liquid crystals, which turn into a solid state by the process of polymerization. According to members of a team led by Jan Lagerwall, principal investigator of the study and a professor in the Department of Physics and Materials Science, the material can be used to introduce tailor-made graphical information in the environment, which is invisible to humans but easily readable by...Read full articleRelated content from Photonics MediaArticlesIR Imager Merges AI, Thermal Physics to See in the DarkHeat-Assisted Detection and Ranging (HADAR), a patent-pending thermal imaging technology from Purdue University, combines infrared (IR) imaging, machine learning, and thermal physics to visualize...Photonics Spectra October 2023 IssueSelf-Assembled Resonator for Optical Chips Confines Light at Atomic ScaleOptical resonators increase the strength of light-matter interaction by storing light over a long period of time.
