Abstract

X-ray thermography is a novel non-destructive method for visualizing the thermal distribution inside an object on the basis of the slight density changes caused by thermal expansion. The high transparency of X-rays and high sensitivity of crystal-based X-ray interferometry (CXI) provides a means to visualize the three-dimensional distribution of temperature changes with a few-degree resolution. We developed an X-ray thermography system that uses a combination of CXI and monochromated synchrotron radiation. We conducted experiments to visualize the time-resolved dynamical thermal flow in heated water and food with our system and successfully obtained a three-dimensional image of the thermal distribution in heated water.
