Title:
分光測定装置、画像評価装置及び画像形成装置
Document Type and Number:
Japanese Patent JP5609068
Kind Code:
B2
Abstract:
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.
