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 filter 20 and enters a pre-focus lens array 11. The pre-focus lens array 11 focuses the light beam on an opening of a micro aperture array 15. The light beam passed through the micro aperture array 15 diverges, but it is focused with the post-focus lens array 13 on the light detection device 30. 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. |
