Ranging Precision Comparison of Direct and Non-Line-of-Sight LiDAR Systems Based on SNSPD
Фотоника. 2026. Vol. 20. No. 6. P. 414–423.
This paper compares the ranging precision of direct time-of-flight (dToF) and non-line-of-sight (NLOS) LiDAR architectures, both using a superconducting nanowire single-photon detector (SNSPD). Both systems operate at 1550 nm with a 50 ps pulsed laser and time-correlated single-photon counting (TCSPC). The dToF configuration achieved approximately 100 µm precision at 10 m, while the NLOS configuration achieved 500 µm precision for a hidden object 0.5 m behind a reflecting wall. The comparison shows that dToF provides superior precision due to the direct optical path, whereas NLOS suffers from additional temporal spread caused by multiple scattering. These results provide quantitative guidance for selecting the appropriate architecture based on application requirements.

Laser communication using satellites represents a promising avenue for data transmission in geographically distant areas without advanced infrastructure. This approach is characterized by its high transmission rate and low power requirements, providing substantial benefits over optical fiber and radio communication. However, the optical channel should exhibit greater transparency for light transmission, resulting in a severely restricted application of this technique for information ...

High-resolution photon-counting optical time-domain reflectometry (PC-OTDR) is crucial for the development of fiber-optic sensing and network diagnostics, allowing accurate fault location and long-haul performance optimization. A major step forward for OTDR is reported by combining a superconducting nanowire single-photon detector (SNSPD) with a low-cost FPGA-based time-to-digital converter (TDC) to perform high-resolution measurements over 150 km ...

We demonstrate an amorphous molybdenum–rhenium (MoRe) film on a thin-film lithium niobate substrate as an efficient superconducting nanowire single-photon detector (SNSPD) operating at T=2.5 K. MoRe films were deposited by DC magnetron sputtering with a composite target of 56 at. % Mo and 44 at. % Re on lithium niobate on insulator substrates at room ...

The integration of superconducting nanowire single-photon detectors (SNSPDs) for state readout in trapped-ion quantum processors is hindered by their sensitivity to electromagnetic interference from ion-trapping radio-frequency (RF) fields. We demonstrate a comprehensive mitigation strategy for niobium nitride (NbN) SNSPDs that combines a conducting, optically transparent tin-doped indium oxide (ITO) shield with a nanowire of optimized ...

Thioflavin T (ThT) assay is extensively used for studying fibrillation kinetics in vitro.
However, the di erences in the time course of ThT fluorescence intensity and lifetime and other
physical parameters of the system, such as particle size distribution, raise questions about the correct
interpretation of the aggregation kinetics. In this work, we focused on the investigation of ...

We report on the design, fabrication and measurement of travelling-wave superconducting nanowire single-photon detectors (SNSPDs) integrated with polycrystalline diamond photonic circuits. We analyze their performance both in the near-infrared wavelength regime around 1600 nm and at 765 nm. Near-IR detection is important for compatibility with the telecommunication infrastructure, while operation in the visible wavelength range ...
