TSR Signal Processing for Accuracy and Sensitivity

TWI's patented Thermographic Signal Reconstruction (TSR) technology has been widely recognized as a breakthrough in the field of thermography.  Conventional approaches to thermography are based on qualitative evaluation of IR images and lack the accuracy and sensitivity required for many critical inspection tasks.

Using a quantitative signal based approach, TSR provides precise, repeatable output with unprecedented depth range, resolution, and measurement capability.

TSR technology has been cited in numerous independent studies and reviews.

Material Characterization

The quantitative nature of TSR allows movement beyond simple defect detection to the performance of sophisticated characterization of materials.  TSR offers precise measurement of sample thickness, defect depth and thermal diffusivity in a wide range of composites, metals, polymers, ceramics and advanced materials. 

Fingerprint
The TSR process can be applied to an entire time sequence in order to create a single "fingerprint" image that facilitates comparison of samples to a defect free reference.
