Abstract

A method for electronically imaging the potential distribution in an electronic component such as an integrated circuit in which the phase of the pulses of the primary electron beam is shifted by a time delay with respect to the potential distribution in the component with a multiple of the frequency of the line deflection of the primary electron beam on the component and a frequency synchronous therewith chosen as the frequency of the time delay.
