| Abstract(in English) | For the application to biometrics idenfitication, a fundamental study was conducted on the reflection-type transillumination imaging that is applicable to thick biological tissue. An inhomogeneous attenuation filter was designed to compensate the inhomogeneity in the transillumination image. With this filter, the intensity resolution was improved 8 times higher and the field of view was enlarged more than 4 times larger. Considering the variation of scattering and absorption characteristics among subjects, an inhomogeneous attenuation filter was manufactured. With this filter, transilluminated vein images were obtained. The images were satisfactory with a homogeneous background intensity and with a good signal-to-noise ratio throughout the field of view. |
