Dear Hopeful Zuiks,
Since there is often interest in Digital imagers on this list here
is a report on current research:
I just read a news item in Science News (Dec 18 & 25 issue)
reporting on the International Electron Device meeting. Dutch researchers
produced a 6 Megapixel imaging chip. Cells are 3 microns with a chip size on
diagonal of 11mm , larger than the current state of the art production imager
chips (quoted as : 9mm diagonal, 3.5micron pixel, 3.2Megapixel.) This is an
experimental chip which is only black and white. It notes it would be bigger
and even more difficult to produce if it included the mcrolensing/filters
needed for color. The article quotes someone from HP as estimating the
resolution would drop by about 25 0.000000or a color version. It sounds like
there
was a fair amount of interest in this paper at the meeting. The article is
somewhat confusing in that if you say you need 3 (RGB) pixels for each full
spectrum pixel for a color imager then the chip only becomes a 2Megapixel
full spectrum device. Maybe there is an easy way to subdivide each pixel for
color in some known way. The article is not at all clear on this. Maybe
somebody could look up the actual article when it is published to get more
definitive details than the Science News Synopsis.
Does anybody know if the current cameras quote pixels in terms of RGB pixels
or "full spectrum" pixels?
Maybe current specs are for RGB pixels not full spectrum.
Regards,
Tim Hughes
