moire measurement device using digital micromirror device

The present invention relates to an image measuring apparatus based on the moire phenomenon, and more particularly to a moire image measuring apparatus using a DMD. Image measurement device using a moire in accordance with the present invention, a light source that emits light; Generating a phase-shifted grating image by controlling said dispersed light, and, (Digital Micromirror Device) DMD radiating the phase shift grating image; An optical splitter for separating the divergent grid image to the first grid image and the second grid images; But the projection image of the first grating on the object to be measured in the first direction, the light projection part 1 that can block the projection of the grid image by the first shutter; Part 2, but the projection light projected on the second grid image to the object to be measured in the second direction, to block the projection of the grid image by the second shutter; Grid image light-receiving portions receiving the grid image reflected from the object to be measured; And comprising: a video processor that performs image processing with respect to the light-receiving grid image, while projecting the first light projecting portion grid image, to block the second optical projection unit projecting the grid image, and conversely the second during the projection of a light projection portion grid image, and blocks the first light-projecting portion for projecting a grid image.
