CMOS AND CCD IMAGE SENSOR BREAKTHROUGHS PROMISE A 'BRIGHT' FUTURE

摘要

Although we've seen numerous CMOS-imager technology developments, CCD developments haven't been idle. Quantum-efficiency (QE) levels of CCD imagers are steadily increasing. QE is a measure of how well a specific sensor responds to different wavelengths of light. The higher the QE, the more sensitive a CCD is at a particular wavelength. Also, CCD imager signal-handling capabilities continue to improve.
