Optical Deflection Monitor JMGD-93XX

Optical Deflection Monitor JMGD-93XX is an image processing-based system designed to measure structural displacement or deformation without requiring additional sensors or signal sources. It captures the state of a structure by taking images and then identifies and tracks passive targets within these images to calculate displacement or deformation. This process not only reduces costs but also enhances monitoring flexibility.

Features

1. Non-Contact Image-Based Monitoring with High Precision
Utilizing high-resolution industrial cameras combined with intelligent DIC image algorithms and edge computing, the system achieves sub-pixel displacement resolution, with measurement accuracy up to 0.05 mm. It operates without contact, eliminating interference with the true structural deformation.

2. Passive Targets
Only simple reflective targets attached to measurement points or the object's natural feature points are required. No power supply or wiring is needed, enabling flexible installation suitable for complex environments and long-distance or elevated measurements.

3. Multi-Point Monitoring with a Single Unit
A single device can simultaneously track multiple targets, enabling synchronous displacement and deflection measurement across several points. This significantly improves monitoring efficiency and ensures data consistency.

4. Dynamic and Static Measurement Capability
The system supports full-scenario monitoring—from long-term static deformation to high-frequency dynamic vibrations—thanks to its high-speed image acquisition and real-time analysis capabilities.

5. Strong Environmental Adaptability
Equipped with automatic light adjustment and compensation algorithms, it adapts to complex lighting conditions such as day/night transitions, rain, fog, and low light. Its IP-rated housing ensures durability for long-term outdoor use.

6. Intelligent Software and Data Integration
Includes a professional analysis platform supporting real-time graphical display, data storage, alert configuration, and report generation. It seamlessly integrates with existing monitoring systems and supports remote control and cloud-based data synchronization.

7. Easy Installation and Low Maintenance
Requires no complex mounting fixtures or on-site calibration, greatly reducing installation time and labor costs. The system is stable and reliable, with minimal need for on-site maintenance.

 

Application

It is widely used for dynamic and static deflection and displacement monitoring of bridge structures, deformation monitoring of large buildings and venues, convergence monitoring of rail transit tunnels, sway monitoring of tall towers and wind turbine blades, settlement monitoring of historical buildings and monuments, vibration and operational posture monitoring of industrial equipment, as well as non-contact displacement measurement in scientific research experiments.
