| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Measurement of a fine defect on a dielectric substrate is difficult because the relationship between the defect shape and the scattered waves is considerably complicated. In this study, we design a computer-generated hologram to discriminate concave defects from convex defects. The hologram operates Fisher's linear discrimination for the scattered wave from the defect. The defect type can be identified from the irradiance of the light wave after passing through the hologram. Compared to conventional optical systems without holograms, the proposed system achieves high discrimination accuracy. We also examine discrimination of the different shape of defects that are not included in the training data of the hologram. | |
