Simultaneous multi-wavelength-band optical frequency domain imaging for spectroscopic investigations
Bibliographic record
Abstract
A novel method of simultaneous multi-wavelength-band common-path optical frequency domain imaging is proposed for spectroscopic applications. Simultaneous multi-band wavelength tuning can be performed by using multiple fiber-ring cavities with corresponding optical semiconductor amplifier as their gain mediums and narrowband optical filters with a single polygonal scanner for synchronization. A simultaneous 1310/1550 dual-band swept laser source is constructed as a proof concept prototype. Broadband 1310/1550 wavelength-division multiplexing is used for coupling two wavelengths into a common-path single-mode GRIN-lensed fiber probe to form a dual-band common-path optical frequency domain imaging. Simultaneous imaging at 1310 and 1550 nm is achieved by using a depth ratio correction method. This technique allows potential for in vivo endoscopic high-speed functional optical frequency domain imaging with high quality spectroscopic contrast with low computational costs. On the other hand, the common path configuration is able to suppress common mode noise and potentially implement high stability quantitative phase measurements.

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.
