SPECTROSCOPIC INFORMATION DETECTION UNIT, SPECTROSCOPIC INFORMATION ACQUISITION DEVICE, SPECTROSCOPIC INFORMATION DETECTION DEVICE, IMAGE EVALUATION DEVICE, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a new spectroscopic information detection unit that detects spectroscopic information on an object by using light from the object.;SOLUTION: A spectroscopic information detection unit 100 comprises: a first opening string member 110; first lens string member 120; second opening string member 130; second lens string member 140; diffraction means 150; and imaging element 160. The diffraction means 150 is arranged on a light path between the second lens string member 140 and imaging element 160; the imaging element 160 is diffracted by the diffraction means 150 and receives light from a diffraction image N(≥1)-th next to a diffraction image formed by positive lenses of the second lens string member 140.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
