Optical Scanner
A device that changes images from either reflection or transparency medium to digital data.
Optical storage
A peripheral device for storing data. It may be WORM or rewritable.
An optical scanner in which the original image remains stationary while the sensors pass over or under it.
Focal Length ...
Many optical scanners are capable of gray scaling, using from 16 to 256 different shades of gray. However, gray scaling is only useful if you have an output device -- monitor or printer -- that is capable of displaying all the shades.
This is an optical scanner in which the original image remains stationary while sensors scan the material from beneath the image.

This is done using an optical scanner that projects the film onto a CCD array and captures it in a raw digital format. Since the different types of microform are dissimilar in shape and size, the scanners are usually able to handle only one type.
CCDs containing grids of pixels are used in digital cameras, optical scanners and video cameras as light-sensing devices.
Flat Bed Scanner - An optical scanner in which the original image remains stationary while the sensors (usually a CCD linear array) passes over or under it. The scanned material is held flat and scanned using a reflective process.
optical registration
a register system employing an optical scanner for obtaining the correct positioning of substrate on a press.
The physical resolution at which a device can capture an image. The term is used most frequently in reference to optical scanners and digital cameras.
