现代光力学测试技术目前广泛应用于工业界和学术界。为了解决生物医学工程形貌测试问题,阴影云纹法应用于口腔齿科领域。通过对磨牙形貌进行相移阴影云纹法测试,得到了4幅干涉图,通过图像处理得到了等值线和三维形貌。结果表明该方法能够用于口腔修复领域,较为清晰地辨别磨牙凹凸部位并以干涉条纹图的形式展现。该测试方法特点是不用对待测物进行加载,可以实现非接触测试待测物形貌。
Modern photomechanical testing technology is currently widely used in industry and academia. In order to solve the biomedical engineering topography test, the shadow moiré method is applied in the field of dental dentistry. Through the phase shift moiré test, the four interference patterns were obtained, and the contour and the three-dimensional topography were obtained by image processing. The results show that this method can be used in the field of oral repair, more clearly identify the molars concave and convex parts and the interference fringe pattern to show. The test method is characterized by no need to treat the object to be loaded, and can realize the non-contact test to be measured.
