Unless you know the questions to ask, selecting the right imaging
technology for your applications can seem more of a coin toss than an
educated choice -- an outright nightmare for those uninitiated in the
intracacies of solid-state imaging science.
Besides the multitudes of charge-coupled devices (CCDs) available
today -- themselves difficult to compare without meaningful universal
standards -- buyers must consider charge-injection devices (CIDs),
complementary metal-oxide semiconductor (CMOS) technology and at least one
hybrid device. Are the application strengths for each technology clear?
Will one work just as well as another? Will the technologies eventually
merge, eliminating the need to choose one?
Imaging experts -- even those who do not manufacture or sell CCDs
-- agree that CCD image quality is a benchmark for other technologies; when
high-resolution is the key to an application, the CCD is the premier
choice. For years these detectors have dominated the imaging market, but
now other technologies are making their way onto the scene...Unless you know the questions to ask, selecting the right imaging

The CMOS Saga
Complementary metal-oxide semiconductor sensors comprise three
types of technology -- passive pixel sensors (a photodiode with a pass
transistor) and two types of active-pixel sensors. The term "active pixel"
originated in Japan and refers to any pixel that has an active element --
at least one amplifier.
