Special Issue Information

Dear Colleagues,

Modern advanced industry equipment relies heavily on advanced sensing technologies to support its rapid development. In the field of equipment testing and monitoring, there has been a noticeable shift from traditional single-dimensional contact electronic sensors to innovative multi-dimensional non-contact optoelectronic sensors. This Special Issue aims to delve into the principles, technologies, and systems of advanced optoelectronic sensors, with a specific focus on their application in the complex working environments, characterized by high temperatures, high pressures, and high speeds. Original research articles and reviews are invited for this Special Issue. Potential research areas may include, but are not limited to, the following: the theoretical and experimental advancements of sensors based on optoelectronic, microwave photonics, and terahertz optoelectronic for precise measurements of displacement, distance, velocity, vibration, temperature, pressure, dynamic stress, and more. Given that validating suppositions often require cross-checking, the use of combined approaches is also encouraged.

We look forward to receiving your contributions.

Understanding microscale dynamic behavior in heterogeneous materials (e.g., polycrystalline or semiconductor systems) under impact loading requires diagnostics capable of resolving ~100 μm features. This study introduces a 19-core fiber-optic array probe with 100 μm spatial resolution, integrated with DISAR velocimetry on a light gas gun platform, enabling two-dimensional continuous measurement of free-surface velocity. The system overcomes limitations of conventional single-point methods (e.g., VISAR’s millimeter-scale resolution and reflectivity constraints) by achieving nanosecond temporal resolution and sub-nanometer displacement sensitivity. Under ~8 GPa impact loading, the probe captures spatiotemporal velocity heterogeneity in polycrystalline materials, including localized pull-back signals and periodic oscillations caused by shock wave reflections at microstructural interfaces. These observations reveal dynamic processes such as damage initiation and evolution, directly linking velocity profiles to microscale material response. The results provide experimental evidence of how grain-scale defects influence shock propagation and energy dissipation, advancing predictive models for extreme-condition material performance. This high-resolution, multi-channel approach offers a paradigm shift in diagnosing heterogeneous material behavior under high-strain-rate loading. Full article
