(a) Schematic of the generation rate , excess carriers density , and image acquisition during one measurement period of length , as reported in the original work of Ramspeck et al. [61]. (b) Relationship between lifetime and phase lock-in phase for several image acquisition times as reported in the original work of Ramspeck et al. [61].
