1.79-GHz acquisition rate absolute distance measurement with lithium niobate electro-optic comb.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
AI-empowered autonomous vehicles must sense the fast-changing three-dimensional environments with high speed and precision. However, the tradeoff between acquisition rate and non-ambiguity range prevents most LiDARs from achieving high-speed absolute distance measurement. Here we demonstrate a lithium niobate electro-optic comb-enabled ultrafast absolute distance measurement method - repetition rate-modulated frequency comb (RRMFC). We achieved an integrated lithium-niobate phase modulator with a half-wave voltage of 1.47 V, leading to over 50 sidebands and a repetition rate can be tuned over 12 GHz in 4 μs. Leveraging these unique features, RRMFC can coherently measure the distance by detecting interference peaks in the time domain, leading to acquisition rates up to 1.79 GHz and a large non-ambiguity range. This single-channel acquisition rate is over 4 orders of magnitude higher than the state-of-the-art absolute distance measurement system. Thus, RRMFC-based LiDAR allows autonomous vehicles to sense the fine details of a fast-changing environment using a single laser.
