Would this new chip revolutionise ccd-astronomy also? It uses fulll
colour
layered sensor array!

If so, it is taking its time. The article is dated Feb 2002

The first camera based on was only just released. Quote from Computer
Shopper a few months back:

"A relatively new approach to the colour problem is the X3 sensor from
Foveon. This uses a three-layer sensor which allows light of different
colours to penetrate the sensor to different depths. You can think of it as
stacking three conventional sensors on top of each other, using one for red,
one for green and one for blue. The result is a sensor that has a true
colour resolution equal to the number of pixels it claims to have and whose
colour quality is far superior to the Bayer filter and doesn't show any of
its colour patterning characteristic. Currently the only camera to use an
X3 sensor is the Sigma SD10 which, at around £1000, is best considered a
professional's camera."
