Abstract
An imaging apparatus is realized which enables a thin finger vein authentication apparatus having a thickness installable in a portable information device. A light beam emitted from an object passes through a visible light cut-off filterand enters a pre-focus lens array. The pre-focus lens arrayfocuses the light beam on an opening of a micro aperture array. The light beam passed through the micro aperture arraydiverges, but it is focused with the post-focus lens arrayon the light detection device. With this structure, a thin imaging apparatus can be obtained with maintained resolution, and a finger authentication apparatus installable in a portable information device can be realized.
