On the morning of July7, 2026, the 20th National Symposium on Laser Micro-Vibration Technology Testing was grandly held at Ningbo University Hotel. Associate Professor Huang Bin presided over the opening ceremony, with Wang Zhiteng, Secretary of the School of Mechanical Engineering and Mechanics at Ningbo University, delivering the opening address. Welcome speeches were delivered by Professor Wang Ji (the conference initiator), Tang Bo (Deputy Secretary-General of the Zhejiang Vibration Engineering Society), Professor Ma Tingfeng (chairperson of the conference), and Mr.Wang Miaojun (General Manager of Zhejiang Shunchuang Intelligent Optics).
Laser micro-vibration testing technology is a non-contact optical measurement technique that utilizes the laser Doppler effect and interference principles to measure vibration parameters of objects. It plays an irreplaceable role in fields such as advanced materials, micro/nanostructures, and aerospace applications.
Wang Zhiteng, Secretary of the School of Mechanical Engineering and Mechanics at Ningbo University, delivered the opening speech.
Academician Zhang Chuanzeng presided over the meeting.
Professor Huang Guoliang (Peking University), focusing on "Non-Hermitian Topological Elastic Dynamics and Its Engineering Applications," proposed a novel sensor design based on anomalous points, demonstrating its ultra-high sensitivity in detecting extremely minor damage and charting the course for next-generation intelligent sensing technologies.
Professor Tang Bo (China Jiliang University) provided an in-depth interpretation of "Laser vibrometer calibration, signal demodulation, and engineering applications," emphasizing the critical role of standardized calibration in ensuring measurement reliability, and outlining the development trends of laser vibrometers toward intelligence, integration, and portability.
Associate Professor Zhang Chao (Nanjing University of Aeronautics and Astronautics) presented on "Structure Damage Identification and Life Prediction Technologies Based on Laser Technology," detailing the application of laser vibration and laser ultrasound in predicting fatigue evolution of composite materials, and demonstrating how digital twin models are employed to achieve condition-based structural health prediction.
Associate Researcher Rui Xiaobo (Tianjin University) introduced the "Contactless Ultrasonic Detection Technology for Aerospace Structural Damage," focusing on sharing innovative applications and engineering achievements of laser-air coupled ultrasonic technology in damage detection of aerospace composite materials.
During the conference, the company showcased its independently developed series of laser vibration meters and established an on-site demonstration and hands-on experience zone. Attendees personally experienced the equipment's practical applications in vibration measurement, modal analysis, and structural health monitoring, offering positive feedback on its high precision, reliability, and user-friendly operating system. This session effectively facilitated technical exchange and industrial collaboration, demonstrating the close integration of industry, academia, research, and application.
This seminar brought together nearly a hundred experts and scholars from universities, research institutes, and enterprises. Through keynote presentations, thematic discussions, and product demonstrations, the event systematically reviewed the latest advancements, core challenges, and future directions of laser micro-vibration testing technology.
The conference concluded successfully on the afternoon of July 10, laying a solid academic and exchange foundation for the high-quality development of laser micro-vibration testing technology in China.
