Imaging technology has a rich history that began thousands of years ago. The reflection from a pool of still water or a shiny metal surface was arguably the first imaging method routinely used by mankind. With the advent of lenses, many other novel forms of optical imaging emerged, including telescopes and microscopes.Using a lens, a pinhole camera, and a sensitized pewter plate, Niépce was the first person to permanently record an image. Optical photography and other forms of optical imaging have since become commonplace ....etc

Terahertz (THz) research has received much attention recently. This development is due to the discovery of new THz-radiation sources and detectors such as quantum cascade lasers, photo conductive switches or electro-optic THz- detectors during the last decade. Of particular interest are broadband Thz-spectroscopy and imaging systems operating in the frequency range 0.1-10THz ....etc

MOS transistor is the building block of integrated circuits, and is the engine that powers them. Today?s most complex ICs, such as microprocessors, graphics, and DSP chips, pack more than 100 million MOS transistors on a single chip. Integration of one billion transistors into a single chip will become a reality before 2010. The semiconductor industry faces an environment that includes increasing chip complexity, continued cost pressures, increasing environmental regulations, and growing concern about energy consumption. New materials and techn ....etc

The terahertz transistor design -- a terahertz is a thousand gigahertz, or one trillion cycles a second an evolution of current designs, using new materials such as zirconium dioxide. Smaller transistors go faster but also leak more current when turned off and need a higher voltage to work, zirconium dioxide is a superior insulator that reduces this leakage and thus reduces power consumption while maintaining speed and low voltages. Intel says that the new design will work down to around 0.6v before long. According to Intel, the combined bene ....etc
