Non-Contact Dynamic Displacement Measurement System
DD System
KK-080035-VR
This system uses a high-speed laser displacement sensor capable of up to 500 measurements per second to observe structural displacement and vibration without contact. By employing a specially developed stepped target (DD Target), it enables displacement measurement perpendicular to the laser irradiation direction. When a flat, conventional target is used, the system can also measure horizontal displacement with high precision. *The target must be a dedicated type.

Verification
Through comparative testing on actual bridges with a contact-type displacement sensor, it was confirmed that vertical displacement can be measured with an accuracy of 0.2 mm.
