Optical modeling of a line-scan optical coherence tomography system for high-speed three-dimensional endoscopic imaging
Bibliographic record
Abstract
The optical and analytical modeling of a line-scan optical coherence tomography (LS-OCT) system for high-speed three-dimensional (3D) endoscopic imaging is reported. To avoid complex lens system and image distortion error, an off-axis cylindrical mirror is used for focusing the line illumination on the sample surface and a micro mirror scanner is integrated with the proposed configuration for transverse scanning. The beams are swept on the cylindrical mirror by the micro mirror rotation and finally focused on the sample surface for transverse scanning. A 2mm by 3.2mm en-face scanning is configured with a 2mm focused line and ±3° scanning mirror rotation. The proposed configuration also has the capability of dynamic focusing by the movement of the cylindrical mirror without changing the transverse resolution. The cylindrical mirror enhances the image quality by reducing the aberration. The system is capable of real-time 3D imaging with 5μm and 10 μm axial and transverse resolutions, respectively.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
