Abstract
En 中文
• A laser-PSD based system is developed for bridge deflection monitoring. • The novel laser reflection system provides sevenfold displacement amplification. • The system achieves 5 μm laboratory and 50 μm field measurement accuracy. • The system enables dynamic monitoring for mid-span deflection.
