Cathode Ray Tubes
Cathode Ray Tubes (CRTs) are vacuum tubes that use an electron gun to produce a beam of electrons that is directed towards a fluorescent screen, creating a visible image. In space and astronautical engineering, CRTs have been used in various applications such as in spacecraft displays, radar systems, and scientific instruments. CRTs have advantages over other display technologies in terms of their ability to operate in harsh environments, their high contrast and brightness, and their ability to display a wide range of colors. However, they also have disadvantages such as their large size, high power consumption, and limited resolution compared to modern display technologies.
