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.

我们正在研制一种测量装置，利用宽视场激光显微镜实现全球体的数字成像。在本研究中，我们观察了一个直径为20mm的钢球的整个表面。然后，观察了一个球形硅橡胶人工心脏瓣膜。表面存在大量的微孔。由于心脏瓣膜在人体内使用多年，所以除了表面图像外，还需要对其表面的磨损状态进行检查。因此，用激光位移传感器测量人工心脏瓣膜的形状。基于测量的心脏瓣膜形状，可以结合表面图像了解磨损状态。
