Figure 1
(a) Schematic of a typical SAXSTT setup with two rotational axes. (b) Equivalent projection sphere showing a heuristic quasi-uniform distribution of 240 experimental projections, with approximately 40 rotations at six distinct tilt angles, and blocked projection directions (dark gray) due to geometric constraints. (c) Sequential acquisition of the first 100 projections results in clustered sampling along specific latitudes on the projection sphere. (d) Sequential acquisition of 100 projections generated by our max–min sampling strategy distribute quasi-uniformly.
