Correlation between spatial encoding and THz streaking time tools for 6140 pulses. (a) Arrival time distribution measured by the THz streaking time tool tTHz. (b) Arrival time distribution measured by the spatial encoding time tool tTHz. (c) 2D histogram of arrival time difference tSpatial − tTHz against tTHz. As shown, the difference between the values measured by the two time tools is dependent on tTHz. The solid line delineates the ridge of the plotted 2D histogram data and was found by fitting a fourth-order polynomial to the dependence of the arrival time difference tSpatial − tTHz on tTHz. The dashed line outlines the trend free of systematic errors. (d) Distribution of arrival time difference tSpatial − tTHz. The bin width in (a), (b) and (d) is 2.5 fs and in (c) the bin size is 2.5 fs × 2.5 fs.
