Is raster scan displays same as bit-mapped displays?
raster scan display -based on television technology.where as random scan display based on hard copy devices.raster scan display cannot directly pass electron beam through the scan line..but random scan directed the beam toward the scan line.
What is vector scan?
Scanning mode in which beam is scanning selected areas only; after scanning of selected area is completed beam is turned off and moved to another area to be scanned. It is also called Raster Scan Method.
What is a raster scan display device with example?
The Raster scan system is a scanning technique in which the electrons sweep from top to bottom and from left to right. The intensity is turned on or off to light and unlight the pixel. The beam is swept back and forth from the left to the right across the screen. When the beam is moved from the left to the right, it is ON. The beam is OFF, when it is moved from the right to the left. When the beam reaches the bottom of the screen, it is made OFF and rapidly retraced back to the top left to start again. A display produced in this way is called raster scan display.
What is random scan display in CRTcomputer?
In random scan display the electron beam is directed only to the part of the screen where the picture is to be drawn. Random Scan monitor draw one picture at a time therefore they are also known as vector display.refersh rate or random scan system depends on the number of times to be displayed. Picture definition is stored in an area of memory called refresh display file.
What is the difference between inverted beam and drop beam?
An inverted beam is a beam whose bottom is the same as the slab. A drop beam is a beam that is put under the structural member it supports.
This type of biometric device uses an infrared beam to scan the color pattern surrounding the pupil of the eye?

What are the types of echo sounder?
The types of echo sounders include single beam echo sounders, multi-beam echo sounders, and side-scan sonar. Single beam echo sounders are simpler and used for shallow water depths, while multi-beam echo sounders can cover a wider swath and provide more detailed bathymetric data. Side-scan sonar is used to produce images of the seafloor.
What is a thin fan-shaped x ray beam that rotates around the patient?
CAT scan, or CT image
What is interlacing in computer graphics?
'Interlacing' is a technique of improving the picture quality of a video signal primarily on crt devices without consuming extra bandwidth. In this technique ,each frame is displayed in two passes. In the first pass, the beam sweep across every other scan line from top to bottom. In second pass, the beam sweeps out the remaining scan lines.

Where is thardus in Metroid prime?
He is located in the Quarrantine Cave. In order to get to him, you must possess both the wave beam and the thermal visor. The entrance to the Quarrantine cave is the powerless door at the top of the Ruined Courtyard. You have to blast a near-by conduit (use scan visor to scan it) with the super missile, and then use the thermal visor to see the circuit. Then simply shoot the round circuit with the wave beam and it will put power to the door.
Compare and contrast the operating characteristics of raster refresh system and LCD's system?
Raster Refresh systems:Electron beam is swept across the screen, one row at time, from top to bottom. Each row is referred to as a scan line. As the electron beam moves across a scan line, the beam intensity turns on and off to create a pattern of illuminated spots.LCDs:Operating by producing a picture by passing polarized light from the surroundings or from an internal light source through a liquid-crystal material that can be aligned to either block or transmit the light.
