Computing | Scanner 1. An input device that takes in an optical image and digitises it into an electronic image represented as binary data. This can be used to create a computerised version of a photo or illustration. A scanner may be linked to optical character recognition software allowing printed documents to be converted to electronic text without having to type them in at a keyboard. 2. lexical analyser.

Occupations | Compiles lists of events (collisions of atomic nuclei) from photographs of bubble chamber, cloud chamber, or other particle detector, and operates machine to record characteristics of events into computers: Observes projected photographs to locate particle tracks, locate and count events indicated by tracks, and identify nature of observed events. Receives instructions from scientist directing project as to specific events that are important in experiment, and identifies such events from other events. Turns cranks to move projector and locates point on track under crosshairs of eyepiece. Enters data into computer to record coordinates of particles. Repeats process to record successive stages of tracks resulting from each event to provide information for scientists to identify particles. May use microscope fitted with scales and protractors to scan photographic emulsions previously exposed to direct radiation and to compute direction, angle, length, curvature, density, and depth of tracks from standard formulas.

(From Wikipedia, the free Encyclopedia)
A scanner is a technological device which acquires information from the world and converts it into data, often to be analyzed or stored by a computer.In the context of general computing, a scanner is a device which analyzes a physical image (such as a photograph, printed text, or handwriting) and converts it to a digital image. See scanner (computing).
There is also another type of scanner that is used generally for receiving broadcasts above 30Mhz. They are illegal in some states and countries.
In computer networking, a scanner is a computer program to probe a remote system, typically to discover a vulnerability. See vulnerability scanner.

In telecommunication, the term scanning has the following meanings:
1. In telecommunications systems, examination of traffic activity to determine whether further processing is required.
Note: Scanning is usually performed periodically.
2. In television, facsimile, and picture transmission, the process of successively analyzing the colors and densities of the object according to a predetermined pattern.
3. The process of tuning a device through a predetermined range of frequencies in prescribed increments and at prescribed times.
Note: Scanning may be performed at regular or random increments and intervals.
4. In radar and radio direction-finding, the slewing of an antenna or radiation pattern for the purpose of probing in a different direction.
Note 1: In radar, scanning may be mechanical, using a rotary microwave joint to feed the antenna, or electronic, using a phased array of radiators, the radiated pattern (beam) of which depends on the relative phases of the signals fed to the individual radiators.
Note 2: In civilian air traffic control radar, scanning usually implies continuous rotation of the antenna or beam about a vertical axis. In military radars, scanning may occur about other than a vertical axis, and may not encompass a full 360°.
Scanning is also a term for the medical technique for body imaging.
Scan
In telecommunication, the term scan has the following meanings:
1. To examine sequentially, part by part.
2. To examine every reference in every entry in a file routinely as part of a retrieval scheme.
3. In radar, one complete rotation of the interrogating antenna.
4. In SONAR, to search 360° or a specific search sector by the use of phased array of transducers.
5. To sweep, i.e., rotate, a beam about a point or about an axis.

(From Wikipedia, the free Encyclopedia)
In computing, a scanner is a device which analyzes a physical image (such as a photograph, printed text, or handwriting) or an object (such as ornament) and converts it to a digital image.
Desktop scanner, with the lid raised. An object has been laid on the glass, ready for scanning.
Larger version
Scan of the jade rhinoceros seen in the photograph above. The scanner software was set to 150dpi.
Larger version
Most scanners today are variations on the desktop (or flatbed) scanner. Hand-held scanners, where the device is moved by hand, were briefly popular but are now not used due to the impossibility of obtaining a high-quality image.
Physical description
A desktop scanner is usually composed of a glass pane, under which there is a light which illuminates the pane, and a moving CCD. Images to be scanned are placed face down on the glass, the light turns on, and the CCD and light move across the pane reading the entire area. An image is therefore visible to the CCD only because of the light it reflects. Transparent images do not work in this way, and require special accessories that illuminate them from the upper side.
Scanner quality
Scanners typically read RGB data from the CCD, process it with some proprietary algorithm to correct for different exposure conditions, and send it to the computer via the device's input/output interface (usually SCSI or USB). Color depth varies depending on the CCD characteristics, but is usually at least 24 bits. High quality models have 48 bits or more color depth. The other qualifying parameter for a scanner is its resolution, measured in dpi. Instead of using the scanner's true optical resolution, the only meaningful parameter, manufacturers like to refer to the interpolated resolution, which is much higher thanks to software interpolation. A good scanner (as of 2003) has an optical resolution of 1600 or 3200 dpi, while its interpolated resolution can easily be as high as 19200 dpi.
A good description of the factors involved in scanner quality is at Digital Imaging Guy.
Output data
The final result is a non-compressed RGB image which is typically transferred to a host computer's RAM. Such an image can be processed with a raster graphics program (such as Photoshop or the GIMP) and saved on a storage device (such as a hard disk).
Computer connection
The amount of data generated by a scanner can be very large: a 600 dpi 9"x11" page-sized image requires 100 megabytes of data to be transferred and stored on the host computer. Recent scanners can generate this volume of data in a matter of seconds. Therefore, a fast connection is required.
Early scanners had parallel connections that could not go faster than 70 kilobytes/second. Professional models adopted the SCSI-II connection, which was much faster (a few megabytes per second) albeit expensive, and frequently requiring a dedicated expansion card to be put inside the host computer.
Recent economic models come equipped with USB connections. In its first version, USB was capable of roughly 1 megabyte per second. Recent models use USB 2.0 connections that can transfer about 40 megabytes per second, eliminating the bottleneck.
