Abstract

A convolutional neural network is used to align an orbital angular momentum sorter in a transmission electron microscope. The method is demonstrated using simulations and experiments. As a result of its accuracy and speed, it offers the possibility of real-time tuning of other electron optical devices and electron beam shaping configurations.

Keywords: Beam Shaping; Convolution neural network; Orbital Angular Momentum Sorter; Self-Alignment.
