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
