PURPOSE: To give the overall three-dimensional impression of an observation visual field to an observer by performing constitution from an optical system provided with a specified objective lens structure group and optical elements arranged in two separate partial optical paths behind the objective lens structure group. CONSTITUTION: This device is provided with an objective lens 1 capable of adjusting a variable distance by a user on an object side and changing magnification as well and the objective lens 1 sends out the formed image of a desired visual field to a stipulated intermediate image plane 3. Then, intermediate images generated on the intermediate image plane 3 are passed through the optical elements 4a and 4b by the objective lens structure group 2 positioned behind it and image-formed in two electrooptical image pickup devices 5a and 5b arranged in the respective partial optical paths along the two separate partial optical paths. Then, signals recorded in the electrooptical image pickup devices 5a and 5b are processed further by the well-known form and system. Also, as the appropriate electrooptical image pickup devices 5a and 5b, well-known CCD arrays known in a video camera or the like are utilized for instance. |
