A comparison of spatiotemporal resolution between DLSR-based synchrotron light sources and third-generation synchrotron light sources. It is based on the relationship ϕ = N/(τΔx2), where ϕ denotes the flux density, N denotes the number of photons required to achieve a certain image quality, τ denotes the temporal resolution and Δx denotes the spatial resolution. The typical values we use for the flux density at DLSRs and third-generation synchrotron light sources are 1015 photons s−1 mm−2 and 1013 photons s−1 mm−2 (Nygård et al., 2024; Willmott, 2019), respectively. We further assume that N = 104, as it leads to a signal-to-noise ratio of N/(N1/2) = 100 (Poisson statistics), which can provide high-quality images for most imaging experiments. |
