A Method of Range Walk Error Correction in SiPM LiDAR with Photon Threshold Detection
Photonics, 2022 A silicon photomultiplier (SiPM) LiDAR with photon threshold detection can achieve high dynamic performance. However, the number fluctuations of echo signal photons lead to the range walk error (RWE) in SiPM LIDARs.

Understanding the Nonlinear Response of SiPMs
SensorsA systematic study of the nonlinear response of Silicon Photomultipliers (SiPMs) was conducted through Monte Carlo (MC) simulations. The MC code was validated against experimental data for two different SiPMs. Nonlinearity mainly depends on the balance between the photon rate and the pixel recovery time.

Spatially resolved dark count rate of SiPMs [PDF]
The European Physical Journal C, 2018 The Silicon Photomultiplier (SiPM) is a promising photo-detector for a variety of applications. However, the high dark count rate (DCR) of the SiPM is still a contemporary problem. Decreasing the DCR would significantly broaden the range of possible applications.

Beyond mechanics: Maximum‐likelihood‐driven PET detector alignment calibration
Medical Physics, Volume 53, Issue 1, January 2026.Abstract Background Accurate quantification is a cornerstone of positron‐emission tomography (PET), yet mechanical inaccuracies during detector assembly continue to undermine this goal. Deviations from intended design geometries arise due to factors such as manufacturing tolerances, mechanical stress, and cumulative errors during module installation ...

An Extended Amplitude Range Readout Circuit for Charged Particle Detection–BEAR 2
Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract Charge sensitive amplifiers (CSA) form the first stage of most detector readout circuits. The operating range of the readout circuits depends on the saturation limits of the Charge sensitive amplifiers, thereby limiting the range of the detector system as well. A number of methods have been introduced to extend the dynamic range of the readout

Analog SiPM in planar CMOS technology
2014 44th European Solid State Device Research Conference (ESSDERC), 2014 Silicon Photomultipliers (SiPMs) are emerging single photon detectors used in many applications requiring large active area, photon number resolving capability and immunity to magnetic fields. We developed planar analog SiPMs in a reliable and cost-effective CMOS technology with a total photosensitive area of about 1×1 mm2. Three devices with different

Research Progress of Microfluidics in Radiopharmaceutical Quality Control
iRADIOLOGY, Volume 3, Issue 6, Page 401-420, December 2025.A complete PET imaging process includes five key steps: nuclide production, PET tracer synthesis, packaging, quality control and PET scanning. Taking the most classical synthesis process of [18F ]‐FDG tracer as an example, its synthesis process includes several core steps, such as: (1) the synthesis of [18F ]‐FDG Tracer, (2) the synthesis of [18F ]‐FDG
