Charge-coupled devices (CCDs), the other kind of sensor often used in scanners, use mirrors to bounce light to a stationary sensor. Scanners using CISs are much smaller than ones that use CCDs, use typically a tenth as much power, and are particularly suitable for low power and portable applications, often powered over USB.

Alexander Murray and Richard Morse invented and patented the first analog color scanner at Eastman Kodak in 1937. Intended for color separation at printing presses, their machine was an analog drum scanner that imaged a color transparency mounted in the drum, with a light source placed underneath the film, and three photocells with red, green, and blue color filters reading each spot on the ...
The important difference between a CCD reader and a pen or laser scanner is that the CCD reader is measuring emitted ambient light from the barcode, whereas pen or laser scanners are measuring reflected light of a specific frequency originating from the scanner itself. LED scanners can also be made using CMOS sensors, and are replacing earlier ...

This led to the 1990 introduction of the step-and-scan systems, which combine a stepper system with a scanner that images only a portion of the mask at a time. Doing so allows much better focus over the tiny part of the mask, although it also makes the IC production process much slower.
A shark attack off Egypt's Red Sea coast killed a tourist and injured another, authorities said Sunday, with an Italy foreign ministry source identifying both as Italian nationals.
