A review of SPAD array chip design for direct time-of-flight LiDAR.
Review in Discover nano, 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
As the requirements of LiDAR for data processing volume, ranging accuracy, and anti-interference capability continue to rise, significant transformations have occurred in recent years in the system architecture, data flow design, and algorithm modules of LiDAR receiver chips. This paper reviews the current design status of direct Time-of-Flight (dToF) ranging sensor chips, focusing on three key aspects for systematic summarization: first, innovations in ranging methods, covering two novel technical schemes, namely histogram-free and variable histogram resolution; second, anti-interference and accuracy optimization, including the chip's suppression of ambient light, mitigation of inter-LiDAR interference, and calibration methods for ranging accuracy; third, comprehensive design optimization of chip Power, Performance, and Area (PPA). Finally, several targeted improvement suggestions are put forward to address existing design bottlenecks, providing references for the subsequent research and development of ToF ranging sensor chips.
