1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Metalens arrays hold great promise for compact light-field imaging systems owing to their compactness and wavefront shaping capabilities. However, their fixed focal lengths fundamentally limit depth-of-field modulation and axial scanning, restricting their adaptability to diverse light-field imaging scenarios. Here, we demonstrate adaptive light-field imaging using a varifocal Alvarez metalens array. The array is composed of two closely bonded metasurfaces, each patterned with 24 × 20 cubic-phase sub-regions. Through relative lateral displacement, the Alvarez metalens array achieves continuous focal length tuning from 3.33 mm to 4.50 mm. Integrated into a plenoptic imaging system, the proposed metalens array enables dynamic focusing and an expanded depth range. We further introduce a MultiLensFusion algorithm that combines these multi-focus captures into high-resolution, all-in-focus renderings. This work offers a compact and versatile platform for next-generation light-field imaging systems with dynamically tunable optical response.
