Abstract
Based on the principles of digital speckle shearing interferometry,the technique for measuring 3Dshape of an object was studied.For the method,the speckle field of the object light beam was deflected by inclining mirror and the speckle fields before and after mirror inclining were recorded by CCD.It substituted traditional special interference fringe obtained directly by using shearing element and reduced the energy loss of the object light beam caused by shearing element.MATLAB software was used to make precise control on the parallel and directional shifting of the speckle shearing interference fringes,then 4interferograms were obtained and four-step digital phase shifting was realized.Traditional mechanical shifting technology with phase controller in reference light beam was substituted and 3D shape measurement was realized.This method omitted the chemical processing of photographic film, and hardwares such as piezoelectric translator were unnecessary.Experimental results show that not only the testing system and experimental process are simplified,but the measurement precision is improved to be up to 1/10wavelength.

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
