Because the geometric relationship between the charge-coupled device
, the light source, and the etching is known, the location of the shadow on the video image reveals the distance to the object's surface.
The camera, derived from the Contax N1 film camera, will feature a charge-coupled device
(CCD) of up to 6 million pixels, making high-quality, fine-textured images possible to meet camera buffs' demands.
To make a digital image, the light passes instead to about a million light detectors that reside in a charge-coupled device
, which operates like a television camera.
The robot, which has a charge-coupled device
(CCD) camera on its head to enable it to recognize its surroundings, can also recognize and speak 20 prerecorded words.
Using a charge-coupled device
, the Stuttgart group showed that siloxene materials can emit a rainbow of colors, including porous silicon's red and blue, a color not yet reported from porous silicon and one crucial for creating color displays or signs, Brandt says.
We could actually see the image."With a detector known as a charge-coupled device
, they picked up images of more complicated objects, such as letters of the alphabet.
To analyze galactic light as discrete points, the astronomers relied on a highly sensitive, computer-chip-like detector known as a charge-coupled device
(CCD), which contains a grid of light-sensing elements.
This image was made through a visible-light filter equivalent to the one on the space telescope, using the same kind of charge-coupled device
to detect the star cluster's light.
Luu use images taken with a charge-coupled device
(CCD), which can detect faint optical light with 100 times the sensitivity of photographic film.
