Patent number: 9835841Abstract: 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.Type: GrantFiled: April 18, 2014Date of Patent: December 5, 2017Assignee: SOMETECH CO., LTDInventor: Hee Bong Yang
