    • A spectrometric measurement apparatus includes a light radiation unit for radiating light onto a medium; a hole array including openings arranged one-dimensionally for transmitting diffusion light from the medium; an imaging optical system configured to focus an image from the hole array; a diffraction element configured to diffract the light for focusing the image; and a light receiving unit including pixels arranged one-dimensionally configured to receive the light that has been dispersed by the diffraction element and spectrometric sensors each corresponding to a predetermined number of the pixels. The light transmitted through each of the openings of the hole array is dispersed by the diffraction element, and then the light enters the pixels so that spectral properties of the diffusion light are acquired. The structure of the diffraction element includes variations that are formed in accordance with the height of the image that is focused by the imaging optical system.
    • 光谱测量装置包括用于将光照射到介质上的光辐射单元; 孔阵列,包括一维排列的用于从介质传播漫射光的开口; 成像光学系统,被配置为聚焦来自孔阵列的图像; 被配置为衍射用于聚焦图像的光的衍射元件; 以及光接收单元,其包括被一维地配置为接收由衍射元件分散的光和各自对应于预定数量的像素的光谱传感器的像素。 穿过孔阵列的每个开口的光被衍射元件分散,然后光进入像素,从而获得漫射光的光谱特性。 衍射元件的结构包括根据由成像光学系统聚焦的图像的高度形成的变化。
