Cars with Night Vision
Science, Shopping, Tech
Popular Science recently conducted a test of Mercedes-Benz (see picture on right) and BMW's new infrared night vision systems. What they found was pretty impressive. Both use infrared to detect obstacles; however they differ in applications.
The Mercedes-Benz projects near-infrared light almost 50 feet down the road. The light is invisible to the eye but reflects off objects and is detected by a camera. The image is then displayed on a very bright screen in the instrument panel.
The BMW uses passive infrared technology, a thermal imaging camera detects heat from objects nearly 1,000 feet away. The dashboard screen is not as bright as the Benz, but detects people and animals much better.
