Figure 3. Typical profile of ρ(n; δ), the ratio of fluorescence gain through splitting the exposure time-span t_E into n pieces, as described by Eq. (4).

(a) Profile of for a given δ. (b) For a given n, is a monotonically increasing function. (c) Profile of , which determines the profile of . The chosen values of the parameters are based on experiments (see Fig. 7 and Table 2).
