WIPO Patent Application WO/2017/056479

A1

A system includes: an illumination device; and an imaging device configured to capture an image of a target which is irradiated with light by the illumination device. The illumination device includes: a light emitting unit configured to emit first polarized light; a condensing unit configured to focus light emitted from the light emitting unit; a diffusion unit configured to diffuse the light focused by the condensing unit; and a uniformization optical system configured to receive the light diffused by the diffusion unit, uniformize an illuminance distribution of the light, and emit the light. The system further comprising a selective transmission unit provided on an optical path from the target to an imaging element of the imaging device and configured to block the first polarized light at a predetermined blocking ratio.
