“…These differences are explained by muon attenuation and electronic noise from the detector. In Colombia, the MuTe telescope [22,5,23] uses rectangular cross-section bars made of organic scintillator, wavelength shift optical fibers, photomultipliers, and acquisition electronics. It is a hodoscope composed of arrays of scintillator bars called panels, each consisting of N i × N j bars.…”

“…The accuracy of the obtained image depends mainly on the spatial resolution of the instrument and the exposure time. In Latin America detectors have been developed for this purpose, such as the study of the internal structure of the Pyramid of the Sun in Mexico [4] and the MuTe project in Colombia [5,6]. Some designs are made up of arrays of plastic scintillators, a material capable of producing luminescence when a charged particle passes through them.…”

Muon radiography, also known as muography, is a non-destructive geophysical technique for the study of the internal structure of large objects such as volcanoes. This is possible by constructing an image based on the differential absorption of the directional flux of high-energy atmospheric muons produced during the interaction of cosmic rays with the atmosphere. So this no other source of radiation is required for this technique. Many muon telescopes are being built with crossed scintillator bars and so, the resolution of each panel is essentially given by the total surface of the bar crossings. Enhancing the resolution may require covering the same area with smaller scintillator bars, which adds costs and build complexity as more scintillators and fibers are required. More channels also require more acquisition electronics which have to be synchronized, increasing the complexity of the system, with associated operating issues, and the final cost. In this work, we propose a novel analysis approach to obtain reliable sub-pixel resolution, by measuring and comparing the average signals measured at each end of the scintillation bar. This analysis approach achieves sub-pixel resolutions, augmenting the spatial resolutions of existing designs. To study the feasibility of this technique we designed a laboratory setup, to emulate muon light pulses with a pulsed laser light located at different points
