Figure 9From: A study to develop a robust method for measuring the detection efficiency of free-running InGaAs/InP single-photon detectorsAbsolute \(|E_{n}|\) values of the participant detection efficiency with respect to the weighted mean value \(\overline{\eta _{p}}\). An \(|E_{n}|\) value less than 1 indicates that the measurement results are metrologically consistent within the measurement uncertaintyBack to article page
