With a max screen size that can hit 300-inch on a peak luminance of 5,000 lumens, the Optoma UHZ68LV 4K is a TV killer.

The USS Preble is the only U.S. destroyer armed with the HELIOS, which can fire laser beams to destroy fast attack craft and drones.

The US Navy successfully tested its new laser weapon mounted on a warship. The dramatic photo above depicts the High Energy ...

The black and white picture shows a bright laser beam being fired from the Preble during a demonstration at sea to verify and validate the "functionality, performance, and capability" of the ...

That’s where lidar comes in. Like radar, but using light, lidar sends beams from a plane or satellite towards the ground. By measuring the time it takes for the light to be reflected ...

Optoma just put Hisense and Epson on high alert following the announcement of its Optoma UHZ68LV 4K laser projector, one that can hit an eye-searing 5,000 lumens on up 300-inch of screen real estate.

The undated image shows the U.S. Navy testing a weapon system known as HELIOS from the USS Preble destroyer in the middle of the ocean.

Lasers are useful because they produce powerful beams of collimated, coherent light. The fact that laser light is monochromatic (narrowband spectral output) is an advantage much of the time ...
