Abstract
A pixelated MIMO wireless optical communication system is introduced, which transmits a series of time-varying coded images that can be received and decoded by commercial digital cameras. The system exploits the bokeh effect to obtain fixed-scale images at all link distances by placing a convex lens in front of the transmitter array at its focal length and focusing the receiver at infinity. This spatial-angular mapping simplifies the receiver structure requiring no re-focusing as the receiver moves. As an additional benefit, this mapping can also be exploited to provide location information to the receiver. The channel model is measured and modeled and rateless codes are applied to track the truncation of receive images for various link ranges and angular offsets. A proof-of-concept optical communication system is implemented with an LCD display and a high-speed CMOS camera.

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
