Non-Contact Vibration Measurement · Automated Point Scanning · Structural Modal Analysis
The PVM-100 Pan-Tilt Scanning Laser Vibrometer from Beijing VIPICO Optoelectronics Technology Co., Ltd. (brand: VIPICO) combines a laser vibrometer front end, a two-axis pan-tilt unit, RGB-D visual positioning, synchronous data acquisition, and modal analysis software in one measurement system. It acquires structural surface vibration responses through point-by-point scanning and supports measurement-point planning, vibration acquisition, data-quality review, and result visualization for large structures, complex curved surfaces, and lightweight thin-walled components.
Automotive and components: body panels, braking systems, interior panels, and NVH testing; aerospace: blades, skins, and lightweight composite structures; machinery: machine tools, motors, compressors, and gearboxes; electronics and electroacoustics: PCBs, loudspeaker diaphragms, and miniature components; research and materials: beam and plate structures, composite panels, and structural-dynamics research. The system configuration for a specific task should consider target size, vibration frequency range, working distance, and surface condition.

Application title: A Pan-Tilt Scanning Vibrometry and Modal Analysis Method and System
Application number: 202611231988.1
Application type: Chinese invention patent application
Published status: According to the VIPICO website, the application has passed the preliminary examination of the China National Intellectual Property Administration.
The information above concerns a patent application. Passing preliminary examination does not constitute grant of a patent. The latest legal status is subject to the records and official notices of the China National Intellectual Property Administration.
The following system-level specifications are published on the official product page. Detailed values are presented in a copyable text table. Maximum and customizable values should be confirmed for the actual hardware, working distance, target surface, and test settings. They do not imply that all maximum specifications can be achieved simultaneously in a single configuration.
The system mainly consists of a laser vibrometer front end, a two-axis pitch/yaw positioning mechanism, an RGB-D 3D vision device, Ethernet-based synchronous data-acquisition hardware, and host software. The software workflow covers parameter configuration, position calibration and grid creation, scanning measurement, data review, modal analysis, reporting, and data exchange. It supports analysis and quality-assessment tools such as stabilization diagrams, CMIF, MAC, MPC, and Auto-MAC. Specific modules are subject to the project configuration.
Product price: quoted by configuration; the final amount is subject to the formal quotation. Within the PVM-100 series, complete-system pricing varies with the laser vibrometer front end, working distance, acquisition channels, vision accuracy, modal-analysis software, excitation accessories, and customization services.
When requesting a quotation, specify the quantity, test object, distance, frequency range, amplitude range, and analysis objectives. The quotation should separately confirm the equipment and software lists, accessories, taxes, shipping, installation and training, acceptance, and after-sales costs so that offers can be compared on an equivalent configuration basis.
Selection and operating documents are available from the supplier. Equipment connection, calibration, laser safety, and troubleshooting must follow the official user manual corresponding to the delivered hardware and software versions.
Confirm the test requirements and environment → connect the equipment and configure acquisition parameters → perform position calibration and create the measurement grid → run a trial acquisition and inspect the signals → start automated scanning → review the data and repeat measurements where necessary → perform ODS / OMA / EMA analysis → export the report and project data.
It is designed for multi-point, non-contact vibration testing of blades, automotive body panels, beams and plates, composite structures, PCBs, loudspeaker diaphragms, and similar objects. For tasks with many measurement points, surfaces that are difficult to instrument with response sensors, or a need to observe the spatial distribution of vibration, automated scanning and the supplied software can provide response data and visualized results.
A single-point vibrometer primarily acquires the vibration response at one location. A pan-tilt scanning vibrometer measures multiple locations sequentially along a planned path and organizes their spatial responses using point geometry and reference signals, making it suitable for mode-shape visualization and modal analysis. The PVM-100 scans points sequentially; it does not acquire all points simultaneously.
Under suitable experimental modal analysis (EMA) or operational modal analysis (OMA) test conditions, the supplied analysis software can identify natural frequencies, damping, and mode shapes. EMA requires a suitable force reference and excitation configuration. OMA requires common response references and applicable operating conditions. ODS primarily visualizes operational deflection at a specified frequency and cannot directly replace natural-mode parameter identification.
No contact response sensor needs to be attached at each laser scanning point, which helps reduce mass loading and cabling effects on lightweight, thin-walled parts. Depending on the t
