Tradeoff between coherence and pixel photon number incurred by binning. Distributions of instantaneous, local MCD values, γ_SR [Eq. (8) without time- or sensor-element-averaging], across pixels for different amounts of binning (N_Pixel), with a_Slit = 1 and 1702 random sample modes interfering with a fixed reference MMF pattern of either 1702 (a) or 500 (b) modes. (c) ${\overline{N}}_S$ and simulated ${\overline{\gamma }}_{\mathit{SR}}$ versus N_Pixel based on 400 random sample MMF patterns, with different N_Mode (open symbols). (d) SANRs calculated based on Eq. (10) from ${\overline{\gamma }}_{\mathit{SR}}$ and ${\overline{N}}_S$ shown in (c) (open symbols). Corresponding SANRs calculated from MMITMs are shown as solid lines in (c) and (d) for comparison.
