Abstract
A deconvolution protocol is developed for obtaining material responses from time-resolved small-angle
scattering data from light (SALS), X-rays (SAXS), or neutrons (SANS). Previously used methods convolve
material responses with information from the procedure used to group data into discrete time intervals,
known as binning. We demonstrate that enhanced signal resolution can be obtained by using methods
of signal processing to analyze time-resolved scattering data. The method is illustrated for a timeresolved
rheo-SANS measurement of a complex, structured surfactant solution under oscillatory shear
flow. We show how the underlying material response can be clearly decoupled from the binning
procedure. This method greatly reduces the experimental acquisition time, by approximately one-third
for the aforementioned rheo-SANS experiment.
