Abstract
In this paper, we address the calibration of the quantum efficiency of single-photon cameras using radioluminescent light sources. The proposed methods are subsequently compared with absolute calibration techniques based on the detection of correlated photon pairs. Furthermore, we propose a method for transferring absolute calibration using the aforementioned radioluminescent emitters.
