Paper Abstract

Second generation image intensifiers are generally used with cathode illuminations so low that the system performance is significantly degraded by quantum noise. The noise arises from the inherent quantum nature of the detected radiation and the statistical variation in the gain of the intensifier. A signal to noise measurement made under specified conditions provides a quantifiable assessment of this characteristic for any image intensifier. The conditions that are now generally used in specifications are given and a method of measurement described. Also methods of determining the individual contributions to the overall signal to noise ratio are described.
