LuminaOSL: Development and Experimental Validation of a Modular Automated Platform for Optically Stimulated Luminescence Measurements.
Article in Sensors (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Optically stimulated luminescence (OSL) is widely used in radiation dosimetry and luminescence research, creating a continuing need for flexible measurement systems capable of supporting diverse experimental protocols. In this study, LuminaOSL was designed and developed as a modular, automated, computer-controlled research platform for implementing different OSL measurement protocols. The platform integrates programmable LED-based optical stimulation, photomultiplier tube (PMT)-based photon counting, an automated eight-position sample mechanism, microcontroller-based control, and a Python-based user interface within a unified architecture. System performance was evaluated through repeated measurements using beryllium oxide (BeO), low-signal control tests, and CW-OSL and LM-OSL experiments. A cycle-to-cycle coefficient of variation of 0.41% was obtained over successive measurement cycles, with no missing data observed during data acquisition and transfer. BeO measurements yielded monotonically decreasing CW-OSL responses under constant optical stimulation and peak-shaped LM-OSL responses under linearly increasing optical stimulation. These findings indicate that LuminaOSL can support stable and reproducible measurements through the integration of programmable optical stimulation, automated sample handling, and time-controlled photon counting, with potential applicability to radiation dosimetry and smart healthcare engineering research.
