This microscopic scale and sensitivity allows the sensor to map a high-resolution image of electrical charge that occurs over the surface of a source material (for example a human finger), when it makes contact with a thin insulating surface (ie a plastic surface).

The resulting charge-parity symmetry solved the mirror-image problem in theory.

The key difference is that instead of focusing the light on a strip of photochemical film as in traditional cameras, digital cameras use an image sensor, called a charge coupled device (CCD), to capture the image.

The company, which also sells image-sharing services for physicians to about 160 hospitals, is offering those hospitals additional technology at no extra charge so they can offer image-sharing directly to their own patients through the federal project, says Hamid Tabatabaie, LifeImage chief executive.

In both the Bush and the Obama Administrations, the leading agency in charge of this policy seems to be the State Department whose philosophy is to try to improve the image of the United States in Latin America in order to mitigate the effect of anti-Americanism in the area.
