Abstract

fetched live from OpenAlex

We propose a tomographic method for point source inline holographic microscopy. By recording a set of holograms at different illumination angles, shadowing effects are eliminated resulting in three-dimensional images with the same precision at the micrometer-scale in all directions. The advantage of our tomographic approach is that it works for both absorbing and phase objects, regardless of the change of refractive index at interfaces. We develop the method with computer simulations and demonstrate its strength by presenting experimental results for micrometer-sized polystyrene beads and a cotton fiber.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
