Uncooled detector, optics, and camera development for THz imaging
Bibliographic record
Abstract
A prototype THz imaging system based on modified uncooled microbolometer detector arrays, INO MIMICII camera electronics, and a custom f/1 THz optics has been assembled. A variety of new detector layouts and architectures have been designed; the detector THz absorption was optimized via several methods including integration of thin film metallic absorbers, thick film gold black absorbers, and antenna structures. The custom f/1 THz optics is based on high resistivity floatzone silicon with parylene anti-reflection coating matched to the wavelength region of interest. The integrated detector, camera electronics, and optics are combined with a 3 THz quantum cascade laser for initial testing and evaluation. Future work will include the integration of fully optimized detectors and packaging and the evaluation of the achievable NEP with an eye to future applications such as industrial inspection and stand-off detection.

How this classification was reachedexpand
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.
