Abstract
We demonstrate a real-time terahertz time-domain electric field registration system, with the system utilizing a permanent-magnet electrodynamic exciter (mini-shaker) with its movement being resolved via an interferometric tracking method. This system is used to record a terahertz electric field, with the signal being encompassed within a scan range of several picoseconds and the system being capable of realizing a single-digit femtosecond precision in the delay axis. The real-time rapid-scan system is shown to exhibit a 47 dB signal dynamic range for a THz electric field measurement consisting of the average of 300 scans. Measured THz signals show excellent agreement with the traditional step-scan system. As the developed system permits real-time monitoring of terahertz electric fields (along with a higher delay-axis precision) compared to traditional step-scan terahertz time-domain spectroscopy), we envision this system being used for critical applications such as environmental gas detection, security checks, radar monitoring, and among others.

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 it
