Muon imaging: Principles, technologies and applications

Abstract During the last 15 years muon-based imaging, or muography , has experienced an impressive development and has found applications in many different fields requiring penetrating probes. Structures of very different sizes and densities can be imaged thanks to the various implementations it offers: either in absorption/transmission or in deviation modes, not to mention the muon metrology for monitoring. The goal of this paper is to give an overview of the main principles of the muography, as well as the technologies employed nowadays and its current and potential applications. Considering the amount of studies dedicated to muography and the number of projects conducted in the last decade, this review focuses on the fields which are the most representative of the muography capabilities.
