Structural Health Monitoring 2
Common light sources in SHM include SLEDs, narrow linewidth lasers, tunable lasers, and broadband sources, with each tailored to specific sensing methods such as FBGs, distributed sensing, and interferometry. The choice of light source depends on factors like resolution, range, and the type of structural parameters being monitored.

Our 2 key focus solutions for providing light sources in SHM:
|
A. Providing Coherent sensor technology which are important in (SHM) because they provide high-precision measurements by utilizing the phase information of light, enabling the detection of very small changes in strain, vibration, or displacement. Lasers with narrow linewidths are essential for high-resolution interferometric sensors.
|
B. Having a wide catalogue of photonic-based lasers and SLEDs, which are crucial for SHM as these sources offer the flexibility needed to cover different wavelengths, power levels, and coherence properties, ensuring compatibility with various sensor types. SLEDs with broad spectral bandwidth are ideal for low-coherence sensing, reducing noise and enhancing measurement accuracy.

Selection Factors for SHM Light Sources:
1. Wavelength: Depends on the optical sensor type (e.g., FBGs, interferometers) and environmental conditions.
2. Power Output: Sufficient to ensure long-range sensing while avoiding fiber damage.
3. Coherence Properties: Low coherence for interferometry; high coherence for Brillouin or Rayleigh scattering.
4. Spectral Bandwidth: Determines the resolution and range of sensor interrogation.
5. Environmental Stability: Resistance to temperature fluctuations and mechanical vibrations.
