Abstract
A stereo microscope includes a stand, two optical image acquisition units configured to connect to the stand to capture a stereoscopic image, which define an imaging plane using two optical axes of the image acquisition units, a pair of video glasses including two optical image reproduction units, each having an optical axis and a display for reproducing an image, which together define an image plane, wherein the optical image reproduction units are arranged to produce a stereoscopic image impression, and two optical axes of the optical image reproduction units define an image reproduction plane, a detection device configured to determine spatial orientation of the video glasses, the image reproduction plane, the image plane and the imaging plane, and a control unit configured to pivot the stand so that the intersection lines of the image plane and the imaging plane on the image reproduction plane are made parallel. Methods are also disclosed.
