CMOS Sensors Expand Their Universe
What a difference a year -- or two -- makes with imaging technology. First-generation cell-phone cameras, for example, primarily used CCD sensors, but the cost benefits of CMOS technology, as well as increasing consumer demand for smaller handheld units, soon changed things. Borrow any teenager’s high-tech cell phone to take a picture, and the odds are that the camera relies on a CMOS imager on a chip.To expand the frame of reference, consider recent imaging advances in astronomy.
