Random Scan Systems
Random scan systems, also known as vector displays, are a type of display technology used in computer graphics. They work by drawing images using a series of straight lines, rather than filling in pixels one at a time like raster scan systems.
In a random scan system, the computer sends instructions to an electron beam that moves rapidly across the screen, drawing lines as it goes. The beam is controlled by circuits that determine its position, intensity, and angle of deflection, allowing it to draw complex shapes and curves.
Random scan systems are capable of producing high-quality images with fine detail, but they are not as fast or versatile as raster scan systems. They are best suited for applications where precision is more important than speed, such as in scientific and engineering visualization, or in the creation of technical drawings and schematics.
Random scan systems were commonly used in early graphics workstations and specialized graphics applications, but they have largely been replaced by raster scan systems and modern flat panel displays. However, they are still used in some niche applications, such as in the creation of vector-based graphics for computer-aided design (CAD) and other technical applications.
