Abstract

fetched live from OpenAlex

Abstract Optical security devices based on high‐density microlens arrays on top of printed microimages or interlaced patterns can display high‐resolution image frames with attractive motion effects. However, the effects are so far restricted to a single color due to challenges in printing multiple colors with sufficiently high resolution and precision. This article introduces a viable solution based on microlens arrays above plasmonic colors to enable high‐resolution multicolor image frames with multidirectional motion effects. Plasmonic color pixels comprised of metalized nanowell arrays are implemented to print 2D interlaced patterns with super‐high resolution and nanoscale precision. Using a 2D microlens array of 25 µm lens pitch, 50 color image frames are obtained from a plasmonic color pattern printed with resolution of 10 160 dots per inch. The image frames show multiple colors, which significantly boost the color performance of microlens‐based security devices. The display resolution of image frames reaches 1016 pixels per inch, which is at least six times higher than conventional lenticular images. The color image frames also show excellent motion effects when moving the view point along any arbitrary direction. The presented devices can be advantageous for commercial applications in security, authentication, and product branding.

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.
