Abstract
High-frequency properties of the modulation transfer function (MTF) in electrostatic image tubes with axial symmetry are studied in detail. Based on aberration theory and stationary phase technique, simple but quite precise expressions for MTF asymptotics in the high-frequency ra nge with regard to arbitrary photoelectrons energy and angular distrib utions are obtained. Some important partial cases are considered, and a comparison between the asymptotic and numerical results is carried o ut.
