Measurement of Smartphone Sensor Efficiency to Cosmic Ray Muons

Jeff Swaney, Michael Mulhearn, Christian Pratt, Chase Shimmin, Daniel Whiteson

摘要:

提出了智能手机相机中CMOS传感器对宇宙射线μ子的效率的测量。外部放大器中的巧合表明宇宙射线μ子的通过,允许测量CMOS传感器的效率。所观察到的通量与公认的值一致,并且效率被呈现为从CMOS硅光电二极管像素收集的光电子的数量的函数。这些效率对于理解大规模智能手机网络作为空气淋浴观测站的可行性至关重要。

英文摘要:

A measurement of the efficiency of CMOS sensors in smartphone cameras to cosmic ray muons is presented. A coincidence in external scintillators indicates the passage of a cosmic ray muon, allowing the measurement of the efficiency of the CMOS sensor. The observed flux is consistent with well-established values, and efficiencies are presented as a function of the number of photo-electrons collected from the CMOS silicon photodiode pixels. These efficiencies are vital to understanding the feasibility of large-scale smartphone networks operating as air-shower observatories.
