Each beam image has its own properties, such as source pinhole aperture size, its Point Spread Function (PSF) and copper filter thickness, all of which impact the electron beam size calculation. Until now, these parameters were applied manually to the pinhole device servers for numerical image analysis, so this semi-manual beam size calculator is subject to frequent adjustments and human monitoring. This study looks at feasibility of training and pointing an Artificial Neural Network (ANN) at image stream coming from pinhole cameras in real time, track all detected beam spots and analyze them, with the end goal to automate the whole pinhole beam image processing.
