A team of scientists say they have made the first large-area color sensor free of aliasing effects by stacking red, green, and blue imaging elements. The researchers come from International University Bremen (Bremen, Germany;
www.iu-bremen.de), Research Center Jülich (Jülich, Germany;
www.fz-juelich.de), and the Palo Alto Research Center (Palo Alto, CA, USA;
www.parc.xerox.com).
