Detecting Heat Capacity Changes Due to Surface Inconsistencies using High Absorbance Spectral Regions in the mid-IR

Description:

Reference #: 00827

The University of South Carolina is offering licensing opportunities for this novel method of visualizing surface inconsistencies.

Potential Applications:

Visualization of:

• Seams between boards

• Repairs to drywall

• Variations in concrete

• Repairs to vehicles

• Cracks in foundation

Advantages and Benefits:

This method provides a non-destructive, hands-off technique for the visualization of seams between boards, repairs to drywall, variations in concrete, repairs to vehicles, or cracks in foundation. 

Invention Description:

Most materials absorb strongly in the fundamental IR spectral region (e.g. 3-20 µm).  In regions of fundamental absorbance, the absorption in these bands is so strong that the measured reflectance contains only specular reflection, reflection that is surface-dominated.  Any photons that penetrate the surface are absorbed and, therefore, not re-emitted.  While there is only a small change in the spectrum, the specular reflectance changes substantially when a thin surface coating is present.

Dr. Michael Myrick and his research group have developed a method to visualize inconsistencies in a substrate material.  The method coordinates a thermal infrared sensor or camera with a light source and scanning mirrors to detect changes in heat capacity, thus creating a non-destructive, hands-off technique for the visualization of seams between boards, repairs to drywall, variations in concrete, repairs to vehicles, cracks in foundation, etc.
