Drift Correction of Scan Images by Snapshot Referencing

Kanto Maeda, Qiwen Tan, Taka-aki Yano, Takumi Sannomiya, Tetsuya Kubota, Zac Thollar

A fast high-signal snapshot image is used as a drift-free reference to calculate and remove continuous pixel-by-pixel drift vectors from slow analytical scans.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

A continuous drift vector for every pixel is calculated for a normalized time-field of the scan pattern utilizing a high-signal, fast-scan snapshot as a drift-free reference to guide the correction of simultaneously acquired analytical maps.

C2weakest assumption

The fast-scan snapshot is completely drift-free and the actual drift can be adequately represented by the chosen Bezier or piecewise-linear basis functions.

C3one line summary

Snapshot-referencing drift correction models and removes spatial distortions in S(T)EM scans by using a fast snapshot reference and Bezier or piecewise-linear basis functions to restore hyperspectral data integrity.
