| Research Abstract |
We are developing a measuring device to realize digital imaging of a whole sphere using a wide-field laser microscope. In this study, an entire surface of a steel ball with a diameter of 20mm was observed. Then, a silicone rubber prosthetic heart valve which is spherical was observed. A large number of micro pores existed on the surface. Because the heart valve was being used for many years in the human body, it is necessary to examine the state of wear on the surface other than the surface image. Thus, the shape of the artificial heart valve was measured with a laser displacement sensor. Based on the measured shape of the heart valve, it was possible to understand the state of wear in connection with the surface image.
