Structural health monitoring is crucial for ensuring the safety, reliability, and longevity of critical infrastructure, including bridges, buildings, and aircraft. Traditional Structural Health Monitoring methods often rely on contact sensors, which can be expensive, time-consuming to install, and limited in spatial coverage. However, recent advancements in LiDAR technology, particularly Ommatidia LiDAR’s innovative approach, are revolutionizing Structural Health Monitoring with advanced vibrometry capabilities.
The Limitations of Traditional Structural Health Monitoring Techniques
Conventional Structural Health Monitoring techniques, such as strain gauges and accelerometers, provide valuable data but suffer from several limitations:
- Limited Spatial Coverage: Contact sensors only measure at specific points, making it difficult to capture the overall structural behavior.
- Installation Costs: Installing and maintaining a large network of sensors can be expensive and time-consuming.
- Accessibility Issues: Accessing certain areas of a structure for sensor installation can be challenging or even impossible.
- Environmental Sensitivity: Contact sensors can be affected by environmental factors like temperature and humidity, leading to inaccurate readings.
