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

This study investigates the polarization properties of materials in the short-wave infrared (SWIR) spectrum using a compact division-of-focal-plane imaging polarimeter. The polarimeter is constructed by packaging a micro-polarizer array on top of an InGaAs sensor. Experiments conducted in both indoor and outdoor environments revealed unique transparency, absorption, and polarization behaviors across various materials. Transparent materials such as plastics, silicon, and black glass exhibited high SWIR transmission, allowing internal visualization, while opaque materials like aluminum, wood, and water demonstrated strong absorption. Polarization analysis identified strong linear polarization in birefringent materials and minimal polarization in isotropic ones, with elliptical or circular polarization arising from mechanisms like total internal reflection, complex refractive index, and birefringence. Outdoor observations showed the interaction of polarized skylights with reflective surfaces, enhancing contrast and revealing surface features. These findings underscore the potential of SWIR polarization imaging for applications in non-destructive testing, remote sensing, biomedical imaging, and optical communication.
