Scan may refer to:
*Scan, the act of examining sequentially, part by part
Image scanning, in data processing, the act of optically analyzing a two or three dimensional image and digitally encode it ( digitizeit) for storage in a computer file
*Scan, the resulting computer file from
image scanning(commonly used in the animeand mangaart communities)
*Scan, to examine successively every character or
bitin a digital computer file as part of a data retrieval function, also in data processing

*Scan, to analyze
writingand verse regarding rhythmic and especially metrical structure.
*Scan, a common name for

Scanning may refer to:
television, facsimile, and picture transmission, the process of sequentially encoding the luminosityand optionally the color of a picture or scene, line by line into an electronic signal. It also refers to remotely reconstructing the picture or scene on a display device.
telecommunications, the process of rapidly tuning a radio receiver through a predetermined range of frequencies to select an active radio broadcast. Scanning may be performed manually or automatically.
Counter-scanning, in physical micro and nanotopography measuring instruments like scanning tunneling microscope, atomic force microscope, etc., a way to eliminate image distortions caused by slow drift of the instrument probe relative to a measured sample surface.
radarand radio direction-finding, the slewingof an antenna or radiation patternfor the purpose of probing in a different direction. In radar, scanning may be mechanical, using a rotary microwavejoint to feedthe antenna, or electronic, using a phased arrayof radiators, the radiated pattern ( beam) of which depends on the relative phases of the signals fed to the individual radiators. 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, in teaching reading, the technique for quickly finding specific information in a text while ignoring its broader meaning.
*Scanning, in the
semiconductor electronicstesting industry, to test the logic used in an integrated circuit in a non-functional method by using a special test mode. This mode generally changes the configuration of the device being tested to look more similar to a large shift register. Logical blocks are then tested by loading and unloading this register. (See for instance JTAGBoundary Scan.)
*Scanning, a term for the medical technique for body imaging.
*Scanning, the term for the lowest-level work of a software
compiler, putting together the individual characters of the text of a computer programto form lexemes.
*Scanning, a behaviour in which
preyanimals look around for possible predators.
