A Better Photodetector
Foveon™ is now producing a new
genre of photodetector arrays that will revolutionize digital imagery. Rather than
use the red, green and blue planar triad array of sensors for each pixel, the new
device employs a 3-dimensional structure that senses blue light at the surface,
green about 20 microns down, and finally red at a depth of about 30 microns. This
capability to exploit the dispersive property of silicon has never been achieved
before. Smaller, faster arrays are the result, that need no software to generate
a single, 3-color pixel from three, single-color pixels. Moiré effects and other
artifacts of the averaging calculations of the archaic CCD sensors will be history.
Look for the new cameras as early as Fall of 2003.
