Laser Camera Takes 3-D Pics Half-Mile Away

Using superconducting nanowires and lasers, a new camera system can produce high-resolution 3-D images of objects from up to a kilometer away.

The technology works by sending out a low-power infrared laser beam, which sweeps over an object or scene. Some light gets reflected back, though most is scattered in different directions. A detector measures how long it takes one particle of light, a photon, to return to the camera and is then able to calculate the distance from the system to the object. The technique can resolve millimeter-size bumps and changes in depth from hundreds of meters away.

  1. Well, when you click-through the More - Link to the entire article, you will read this:

    The technology is similar to LIDAR, a remote sensing technique that also uses laser light to measure the distance to different objects. By using infrared light, Buller’s camera is able to detect a wide variety of different items that don’t reflect laser beams well, like clothing. And the long-wavelength infrared light is safer than other lasers because it won’t harm people’s eyes when it scans them.

  2. I found a really wonderful post. You are knocked nail on the head about lactulose supplement review. Optical Express In the event that you're remaining before the mirror, make-up brush at the prepared to apply that exploratory shimmery eye shadow you've been contemplating for some time, the best thing you can do is walk away.
