The Amplitude Effect of Point-Source Blooming as a Function of Background Level in Ebsicon-Type Camera Tubes
Abstract
A laboratory experiment is described in which the amplitude effect of point-source blooming in an ebsicon-type (i.e., intensified silicon-diode array) camera tube is demonstrated as a function of uniform background level. At very low background levels, the signal required for constant video signal-to-noise ratio, as measured on an A-scope, is approximately constant; at intermediate levels, it varies approximately as the one-half power of the background level; and, at high background levels, the power law exceeds unity. An amplitude- degradation function, f, obtained from the measurements, is presented. The importance of the f-function in point-source measurements using an A-scope is discussed.
