Physicists almost double light efficiency in LC projectors

Researchers from North Carolina State University and ImagineOptix Corporation have developed new technology to convert unpolarized light into polarized light, which makes projectors that use liquid crystal (LC) technology ...

Quality of laser beam shaping can be enhanced at no extra cost

Researchers from Osaka University have developed a technique for improving accuracy of laser beam shaping and wavefront obtained by conventional methods with no additional cost by optimizing virtual phase grating. The results ...

The science and engineering behind Amsterdam's "Rainbow Station"

If you're passing through the Amsterdam Central train station you may be pleasantly surprised to see a vibrant rainbow projected on the large arch that spans over its platforms. It's the "Rainbow Station" project by artist ...

Researchers make biodegradable optical components from crab shells

Researchers have developed a process to turn crab shells into a bioplastic that can be used to make optical components known as diffraction gratings. The resulting lightweight, inexpensive gratings are biodegradable and could ...
