Theory of Incoherent-Light Temporal Imaging Systems Based on a Temporal Pinhole
Bibliographic record
Abstract
We present a comprehensive consistent theoretical analysis of a set of recently demonstrated schemes for temporal imaging of incoherent-light intensity waveforms based on the time-domain pinhole concept. Schemes analyzed here include temporal magnification and compression systems, time-to-frequency mapping, and frequency-to-time mapping processes, all involving a suitable combination of optical dispersive lines and a short temporal gate (time-domain pinhole). This paper reports formal derivations of the main performance specifications in the studied incoherent-light schemes, including mapping factors and precise estimates of time/frequency resolutions and operation windows (temporal/spectral field of view), as a function of design parameters, namely dispersion values and pinhole duration. Design equations for system performance optimization are also obtained and theoretical assumptions and design tradeoffs are pointed out and discussed. Our theoretical findings are in agreement with previous simulation and experimental results and are further validated in this report.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
