Abstract
This paper presents two structured-light 3D imaging systems that use a quasi-analogue projection subsystem based on a combination of digital micromirror device (DMD), optics, digital processing and calibration procedure. The first system is a high-resolution prototype that acquires 12M 3D point per frame; the second one is a high-speed prototype that generates 150 3D frames per second, with 2M 3D points per frame. The projection subsystem can produce high frame rates, high contrast and high resolution patterns using off-the-shelf components. The structured light patterns used are the same combination of binary and sine wave fringes as those usually encountered in commercial systems. The proposed systems generate the sine wave patterns using a single binary image, thereby exploiting the high frame rate of the DMD.

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
