Abstract
Multi Digital Silicon Photon Multipliers (MDSiPM), as image sensors, are utilized to calculate and estimate the properties of the incident light. These properties include spatial location of hits, intensity or number of photons and time of arrival. Some characteristics can be more important than others depending upon the problem at hand. Among endless applications where MDSiPMs are used for, Positron Emission Tomography and LiDAR are the two that this thesis is focused on. Positron Emission Tomography is an imaging technique to monitor functional information about tissue and organs, including early cancer lesions. This constitutes the main difference with structural techniques such as radiography, where, by means of Xrays, a projection of a section of the body under test is obtained.
