Single-shot real-time optical imaging using compressed optical-streaking ultra-high-speed photography
Bibliographic record
Abstract
Single-shot real-time ultra-high-speed imaging is of significance in capturing transient phenomena. Existing techniques fall short in possessing satisfying specifications in the imaging speed, sequence depth, and pixel count. To overcome these limitations, we have developed compressed optical-streaking ultra-high-speed photography (COSUP) that records a scene (x, y, t) by applying the operations of spatial encoding, temporal shearing, and spatiotemporal integrating. The COSUP system possesses an imaging speed of 1.5 million frames per second (fps), a sequence depth of 500 frames, and a pixel count of 0.5 megapixels per frame. COSUP is demonstrated by imaging single laser pulses illuminating through transmissive targets and by tracking a fast-moving object. We envision COSUP to be applied in widespread applications in biomedicine and materials science.

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.
