<title>Artifact-free resizing using an optical method</title>
Bibliographic record
Abstract
Pixelated spatial light modulators (SLMs) are commonly used in projection displays. The total number of columns and rows in the device define its `native' resolution. This native resolution may not match the resolution of the signal that is to be displayed. It is common to use electronic methods to re-scale the signal to match the resolution of the panel. This resizing introduces artifacts that may be unacceptable in some applications. A new technique is described using optical methods to obtain an artifact free representation of the signal. This method works particularly well with high- resolution 1.8' diagonal devices where the signals to be displayed have equal or lesser resolution than the SLM. The system requires a zoom illumination system and a zoom projection lens. Information is sent to a sub-area of the panel that matches the native resolution of the signal. The zoom illumination system concentrates the total light flux onto this sub-area. A zoom projection lens adjusts the size of the final image to be constant.

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.
