Abstract

fetched live from OpenAlex

A large aperture matrix of tunable liquid crystal lenses (MTLCL) is used for dynamic presbyopia correction. The special electrode design and driving method allow the activation of local lenses at arbitrary lateral positions of the MTLCL. First, the study of tunable wavefronts, which can be generated by such a device, is presented. Then, the image quality at different viewing angles and distances is quantified. A driving algorithm has also been developed to increase the speed of focusing. It is shown that this device may provide continuous focus tunability (from 0 to 2.5 diopters), react within 0.5 s, operate with relatively low voltages (<5 V), and enable diffraction-limited on-axis aberrations. Finally, the results of a comprehensive evaluation of its performance with human subjects are reported, comparing the visual acuity (VA) achieved by using the approach proposed in this project against the natural human VA for objects in the near field.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
