Abstract
Some common procedures for the evaluation of the parameters of the image converter tube are analyzed on the basis of the physical processes involved in their definition and measurement. A correlation between these procedures is established with a view to facilitate a comparison and selection of image converter tubes in the design of active night viewing systems. Experimental results verifying the correlation are presented. A calibration procedure is suggested and it is shown that it results in precise measurement of conversion gain.
