The LV-SC400 scanning laser vibrometer employs Doppler principle for non-contact measurement, with a range of 0.2m to 20m. Featuring strong anti-interference capability and ultra-high resolution, it accurately measures vibration, displacement, velocity, and acceleration of various objects, while also supporting ODS and modal analysis.
Key Features
The system features a modular design with optional decoders for broad applicability. It enables non-contact vibration measurement of objects, supporting a frequency range up to 3MHz (expandable to 25MHz) with automatic focusing capability. The device is mass-free and non-invasive to the measured object, achieving a maximum measurement speed of 12m/s. Professional capabilities include measuring vibration parameters such as displacement, velocity, acceleration, and frequency, along with ODS (Optical Detection System) and modal analysis. Customization options allow selecting appropriate ranges and frequencies to meet specific requirements. The complete solution integrates optical debugging, circuit noise reduction, signal processing, data acquisition, and software analysis. Personalized software can be configured with intelligent features like real-time measurement evaluation and trend visualization.
Application Area
It is widely used in NVH, structural mechanics analysis, acoustic testing, ultrasonic, automotive and other fields.
Company and R&D Team
The company holds complete independent intellectual property rights with over 50 authorized patents. It possesses comprehensive technical capabilities including optical design, circuit design and control, software algorithm development, and optical assembly debugging, enabling vertical integration from design to application.
The company has developed and marketed over 20 functional laser Doppler vibration measurement instruments, including 3D scanning laser vibrometers, full-field scanning laser vibrometers (covering infrared scanning and microscopic scanning types), microscopic laser vibrometers, infrared fiber laser vibrometers, multi-channel laser vibrometers, long-range laser vibrometers, differential laser vibrometers, and single-point laser vibrometers. These instruments are widely used in domestic universities, research institutes, aerospace, automotive, data storage, industrial, biomedical, and semiconductor manufacturing sectors. The company's products enjoy high recognition in China, serving over 300 universities and research institutions nationwide, with a market share ranking among the top domestic instruments of the same category.
In 2009, the company successfully developed China's first domestically produced laser Doppler vibration analyzer. For over a decade, the team has steadfastly pursued independent R&D, implementing a national strategy to replace imported high-end instruments with homegrown alternatives while maintaining a focused commitment to laser vibration measurement technology. Between 2013 and 2018, the team collaborated with leading Chinese universities and research institutes—including Tsinghua University, Peking University, and Zhejiang University—to complete two major projects: the "Development and Application of Cross-Scale 3D Photoelectric Vibration Measuring Instrument" and the "Micro-Nano Structure Dynamic Characterization Tester," both funded by the Ministry of Science and Technology. Additionally, the team actively participated in drafting national calibration standards for laser vibration analyzers, working with industry peers to address critical technological bottlenecks in China's laser vibration instrument sector.
The company's vision is to become the undisputed leader in the laser vibrometer industry. It will persistently drive independent innovation, continuously refine and deepen its expertise, and make new contributions to the journey of domestic instruments catching up with global advanced levels.
