Abstract
A image acquisition device comprises a light source unit, a digital micro mirror, an optical transfer medium, an imaging unit, and a beam splitter, wherein a single focusing pattern light is formed to be focused on a single specific point when the focusing pattern light penetrates the optical transfer medium, and specific points focused by each of the plurality of focusing pattern lights scan the object to be measured such that the object to be measured is imaged. Therefore, when an image is obtained through an optical transfer medium such as an optical fiber, pixelation and aberration can be avoided regardless of the type of optical transfer medium and an image having high resolution can be obtained fast without a separate scanner.
