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

Miniaturized spectrometers utilizing a single reconfigurable photodetector (PD) are highly attractive in the infrared (IR) range due to their advantages in terms of cost, ease of integration, and reduced system complexity. However, such devices usually suffer from either limited wavelength tuning range or high spectral correlation in spectral sampling. Here, a new concept based on tunable guided mode resonances and surface plasmon resonances in a simple liquid crystal/Au stack is proposed to break the wavelength tuning range limit and simultaneously enable low spectral correlation. A chip-scale IR spectrometer using a single-pixel PbS PD is realized with a remarkably large wavelength tuning range over 850 nm (1150-2000 nm) and high fidelity (mean square error ≈0.001) in spectrum measurement. Such a novel technique is applied in plastic sorting and demonstrated remarkable improvement in sorting accuracy benefiting from its broadband property and distinct spectral responses at various sampling biases. Furthermore, a post-tuned operating mode for efficient and accurate spectroscopy is demonstrated by customizing the wavelength/bias scanning strategies, demonstrating the high flexibility of this technology. Full-vector analysis considering the interface anchoring effect and the anisotropic gradient refractive index distribution of liquid crystal is conducted to reveal the fundamental principles of broadband light modulation.
