Abstract
A method for imaging a sample with charged particles comprises directing charged particles towards the sample along a primary axis, and simultaneously detecting a first portion and a second portion of the charged particles transmitted through the sample with a first detector and a second detector, respectively. The second detector is positioned downstream of the first detector. Each of the transmitted charged particles exits the sample at an exit angle between a direction of the transmitted charged particle and the primary axis. The exit angles of the first portion of the transmitted charged particles overlap with the exit angles of the second portion of the transmitted charged particles. In this way, complimentary information, such as the structural and compositional information, may be obtained simultaneously.
