A method used for estimating the distance between objects in photographic images is the depth from focus (DFF) method. The method has reportedly been implemented many times using only image-side telecentric optical systems because a change in image magnification becomes a problem due to differences in focus positions. Therefore, there have been no examples of this method having been implemented using...
For preparing a “highly lubricated biointerface”, which has both excellent lubricity and biocompatibility, we investigated the factors responsible for resistance to friction during polymer grafting. We prepared poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC), poly(2-hydroxyethyl methacrylate) (PHEMA), and poly(methyl methacrylate) (PMMA) brush layers with high graft density and well-controlled...
