Abstract

Diffusion reversal techniques are integrated into enhanced truncation-correlation photothermal coherence tomography (eTC-PCT) to restore blurred infrared thermophotonic images to their original, undistorted optical resolution. Diffusion reversal imaging shows promise as a general non-invasive biomedical imaging and non-destructive testing tool, with potentially wide range of applications from biothermophotonic imaging of disease and subcutaneous tissues to manufactured product quality control inspection, including green stages of automotive component production. This represents a significant advancement in this field, as it successfully overcomes the traditional limitations posed by lateral and axial heat diffusion.
