FULL-SPECTRUM IMAGE OBSERVATION DEVICE AND COLOR VISION INSPECTION DEVICE

摘要

An objective of the present invention is to project a clear full-spectrum image with a simple configuration without a misalignment arising for each pixel. A full-spectrum image observation device comprises: a light source unit (10) which emits white light; a first diffraction grating (19) which generates diffracted light of the white light; a DMD (22) which optically modulates and reflects color-separated light beams; an RTIR prism (21) which guides the light beams from the first diffraction grating (19) to the DMD (22) and emits the reflected light from the DMD (22); a second diffraction grating (24) which generates the light beams from the DMD (22) which have a desired full-spectrum distribution as adjusted and composited light beams; a galvanometer mirror (29) which deflects and scans the light beams and renders in two dimensions the light beam of each spectrum distribution by time division; and an image forming optical assembly (30), further comprising an ocular lens (31).
