Known as RSOM (raster-scan optoacoustic mesoscopy), the technology incorporates weak laser pulses. This causes the tissue to momentarily expand, which in turn generates ultrasound waves. The sensor is able to detect those waves. RSOM allowed the scientists to determine individuals' skin thickness, capillary density, number of blood vessels, and total blood volume in the skin. Down the road, it's possible that the system could also be used to assess diseases such as skin cancer or diabetes.
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.

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.
