  • Patent number: 9835841
    Abstract: A video microscopy system for displaying a 3D image on a monitor by magnifying a portion that is not easily visually observed or a portion that is generally out of visual reach. The 3D image is displayed on the monitor such that the object can be more realistically observed. The 3D video microscopy system can display the object flat without distortion by focusing the image using an achromatic prism, clearly display the object by removing chromatic aberration, and adjust the convergence angle and the degree of magnification of the object in a simple manner. The 3D video microscopy system includes a pair of image sensors, an achromatic prism focusing an image of an object on the image sensors by removing chromatic aberration thereof, and a pair of magnifying lenses transferring the image of the object that has passed through the achromatic prism to the image sensors by a predetermined ratio.

  • Publication number: 20170212360
    Abstract: Provided is a glasses-free 3D display device capable of implementing a 3D image by directly forming a left image and a right image of an object on a left eye and a right eye, and including: an ocular lens having a curved structure in which a convex portion bulges outwards from a center of the ocular lens, and of which a horizontal length is longer than an interpupillary distance of a user; and a pair of achromatic prisms placed at front sides of a left curved surface and a right curved surface of the convex portion, wherein the achromatic prisms enable optical paths to be corrected so that chromatic aberration, a change in optical axis, and nonlinear distortion are corrected, and the corrected images are magnified and formed on the retina of the eyes while passing through the ocular lens, and thus adjustment of the interpupillary distance is unnecessary.
