Abstract
Significance To provide reference for the further development of particle characterization techniques， process optimization， and improvement of industry standards， this paper reviews the research status of particle measurement technologies， summarizes the existing limitations， and proposes potential research directions.
Progress Over the past decade， particle measurement technologies have made great progress. In addition to conventional commercial particle measurement instruments such as laser particle size analyzers， nanoparticle size analyzers， and particle counters， many other measurement techniques， including imaging method， rainbow scattering， interferometric particle imaging， digital holography， and ultrasonic scattering， have been investigated and significantly developed. Among them， image-based measurement technology stands out prominently. Due to the rapid development of imaging devices， the concept of imaging method has undergone a significant transformation， enabling the trial and practical implementation of many novel ideas. Furthermore， with the continuous progress in measurement technologies， the standardization of reference materials and measurement methods has advanced in an orderly manner and yielded fruitful results.
Conclusions and Prospects It is proposed that particle measurement technologies can achieve systematic upgrading through the interdisciplinary integration of optical detection， microelectronic sensing， and computer image processing， and that mainstream measurement methods should be continuously iterated and optimized to effectively meet the rapid development demands of key fields. For complex particle systems， more advanced inversion algorithms and physical models should be developed. It is urgent to formulate national and international standards targeting multi-dimensional particle characteristics， including morphology and composition spectra， to secure the initiative in standard-setting. Measurement instruments should be developed towards higher resolution， higher sensitivity， and stronger anti-interference ability to meet the extreme requirements of cutting-edge fields. Particle sensors should be developed into intelligent nodes of the industrial internet， and an intelligent decision-making system covering the entire production chain based on particle data should be constructed. Furthermore， novel technologies and instruments applicable to the collection and in-situ analysis of living biological particles and extraterrestrial particulate matter should be developed.
