碩士 / 淡江大學 / 物理學系碩士班 / 95 / This thesis bases on the common X-ray sources to capture and investigate a series of X-ray images and X-ray phase contrast images. In the part of the X-ray images, by changing the magnifications and the spatial coherence length, the target was observed clear. In order to prove that caffeine will affect human beings’ bone density, the researcher has chosen the similar one, zebra fish, as the observation of the experiment. Those zebra fishes were growing up in different water, one is normal water and the other one is caffeine water. From the experimental result, it can find out caffeine will cause the enlargement of the skeleton interval.
Furthermore, this thesis also explores about manipulating Talbot distance and the T. Weitkamp experiment to capture the biological tissue of the X-ray phase contrast images. By adjusting the variables of gratings, the better phase contrast images could be achieved.
