    • 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.
    • 一种系统包括:照明装置; 以及成像装置,被配置为捕获由所述照明装置照射光的目标的图像。 照明装置包括:发光单元,被配置为发射第一偏振光; 凝结单元,被配置为聚焦从所述发光单元发射的光; 扩散单元,被配置为使由所述冷凝单元聚焦的光扩散; 以及均匀化光学系统,被配置为接收由扩散单元扩散的光,使光的照度分布均匀化并发光。 该系统还包括选择性传输单元,其设置在从目标到成像装置的成像元件的光路上,并且被配置为以预定的阻塞比阻挡第一偏振光。
