Rembrandt may have traced his celebrated self-portraits from optical projections created by assemblies of mirrors or lenses, a new analysis suggests. Two U.K.-based researchers -- Francis O'Neill, an ...
As frustrating as having an atmosphere can be for physicists, it’s just as bad for astronomers, who have to deal with clouds, atmospheric absorption of certain wavelengths, and other irritations. One ...
A new study of Rembrandt's self-portraits provides more evidence to theories that the 17th-century artist, among other Old Master painters, used optics to produce his remarkably accurate works. Left: ...
In May 2022, the James Webb Space Telescope (JWST) encountered a problem. The giant observatory, perched 1 million miles from Earth, has a honeycomb-like configuration of mirror panels to see the ...
Immersive reality has a new look coming at the end of November in the form of a clever arrangement of digital projectors, curved screens, mirrors and software for image rendering and stitching, ...
The purpose of optical coatings is to change the reflectivity of optical surfaces. According to the materials and physical phenomena which are used one can in principle distinguish metallic and ...
A side mirror that eliminates the dangerous “blind spot” for drivers has now received a U.S. patent. The subtly curved mirror, invented by Drexel University mathematics professor Dr. R. Andrew Hicks, ...
