TL;DR: In this article, a lock-in infrared thermography (LIT) was used to estimate the sizes and locations of subsurface defects using a fixed number of pixels, where the inspected image is shifted to obtain a shifted image while subtraction of one image from the other gives the shearing-phase distribution.

TL;DR: In this article, a finite element analysis was performed at several excitation frequencies to interrogate the sample ranging from 0.182 down to 0.021 Hz and the relationship of the phase value with respect to excitation frequency and defect depths was examined.

TL;DR: In this article, a lock-in thermography was used to estimate the location and size of the subsurface defect and the phase difference between the defect area and the healthy area.

TL;DR: In this paper, the detection technique of impact damage defect using thermography and ESPI was described, and the results obtained with the two techniques are compared with ultrasonic C-scan testing.

TL;DR: The Korean Undiagnosed Diseases Program (KUDP) as mentioned in this paper has been implemented for three years to solve the problem of undiagnosis patients throughout the country and develop infrastructure, including a data management system and functional core laboratory for long-term translational research.
