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

OCT point spread function phantom measurement demonstrated lateral resolution preservation of the proposed method. Quantitative evaluations using the contrast-to-noise ratio and equivalent number of looks demonstrated that the proposed method significantly outperforms conventional frame-averaging techniques.

C2weakest assumption

The dispersed scatterer model accurately describes the OCT imaging process and that shifting the complex en face OCT signal modulates speckle patterns without introducing new artifacts or resolution loss.

C3one line summary

A speckle reduction technique for OCT that modulates patterns via complex signal shifts and averaging, outperforming frame averaging while preserving resolution.
