Raster Scan or Raster Scanning-- is the rectangular pattern of image capture and reconstruction in television. By analogy, the term is used for raster graphics, the pattern of image storage and transmission used in most computer bitmap image systems. The word raster comes from the Latin word rastrum (a rake), which is derived from radere (to scrape); see also rastrum, an instrument for drawing musical staff lines. The pattern left by the lines of a rake, when drawn straight, resembles the…
Thin Films Nanolithography (XELScanning Probe Nanolithography is a very promising technology for nanofabrication. It uses the probe tip of scanning probe microscope to manipulate materials at nanometer scale. T Figure 1. A Big Buck pattern made on a silicon substrate using bias mode XEL Nanolithography. The pattern is made on a silicon surface using the Raster scan mode.
A staticky hiss, the squeal of a synth, and a television signal struggling to resolve itself. Noticeably absent is that iconic Carpenterian theme, indicating that this will be no ordinary Halloween. Pixelated rows of orange slowly fill in a cathodic void, the lines progressing from the bottom up with a steady electronic breedle. As the raster scan unnervingly carves out shapes in the flickering fuzz, a baleful pulse hints at something truly foul, an analog anathema. You are a child sitting
The Sun in C IV 1548 A as observed by SUMER on 4-5 February 1996. The picture was put together from eight horizontal raster scans across the Sun, altogether 7406 exposures, each lasting 15 seconds. The picture is shown in bins of 4x4 pixels, one pixel being approx. 1 arcsec.
