German researchers have found a way to identify deep fake images by converting them to the frequency domain using the discrete cosine transform. The team, from the Ruhr-Universität Bochum and Casa (Cyber security in the age of large-scale adversaries), point those sceptical about deep fakes to the website www.whichfaceisreal.com – a website whose data set was ...

Gaggione has introduced a 16mm diameter range of optical collimators for LED lighting, optimised not to image the die – giving a smooth beam as a consequence. Made in PMMA (acrylic) and called LLC22, they are “dedicated to single and multi-chip high power LEDs. The range is based on our patented non-chip-imaging technology. The LED chip will ...

Researchers from the University of Southampton have found a way to make an optically-active meta-surface without altering the physical shape of the surface. Infra-red thermal control coatings and non-linear optics are potential applications. Metasurfaces are structures designed to control, for example, electromagnetic radiation using repeating structures, typically with sub-micrometer dimensions for light. Routes to forming ...
