In a process similar to printing a photograph, engineers beam high-powered light through a mask-like image of the chip, creating a duplicate on a silicon wafer.

Ram's heavy duty 2500 and 3500 models come with a rear-facing camera built into the center-mounted brake light behind the cab that can beam images of a trailer or the cargo in the bed into the truck's dashboard screen.

His disquisition on light, aimed at disproving Newton, was way off-beam.

His quest began in 1895, when as a 16-year-old he imagined what it would be like to ride alongside a light beam.

An optical mouse uses a beam of light and an optical sensor to detect movement over a surface -- there are no moving parts.

Each mirror acts as a beam-steering device, controlling whether a single picture element (pixel) in the image is light or dark.

Last year, OPERA measured that neutrinos were making the 454-mile (730-kilometer) underground trip between the two labs more speedily than light, arriving there 60 nanoseconds earlier than a beam of light would.

Optical correlators, meanwhile, work by encoding images on to a beam of light and, using a special lens, transforming them into their Fourier components building-blocks that encode the thickness and direction of lines in the image, but not their position.
