Detonation cells are a characteristic feature of detonation shots, and their size is a very valuable experiment parameter to know. To reduce the uncertainty in this variable that is used to being related to manual measuring, a computational processing has been developed, based on Fourier analysis of digital pictures. The objective is to highlight the relevant frequencies present in the cellular pattern, and thus get the most encountered spatial wave length, which would turn out to be the cell size. This guide is aimed to provide with the tools, knowledge, and advice needed to compute cell size measurements using the Photoshop procedures and Matlab programs implemented and available for free download on the related web site:
