| Outline of Final Research Achievements |
A depth map (3D point cloud) was obtained by a focus variation method (Shape from Focus) which was applied to multiple images stacked by digital refocusing in the light field microscopy. Then, we developed a 3D shape modeling technique based on optical microscopy and Shape from Silhouette method combined with the depth map by light field microscopy. Furthermore, a reflection type OCT (Optical Coherence Tomography) with sample scanning scheme was developed for 3D measurement of deep structure such as a hole. In this scheme, the reference mirror is controlled based on processed images which are acquired to analyze the low-coherent interference signal for height measurement. The depth of field of this method was experimentally verified to be several tens of times as long as a typical optical microscopy.
