Title: Stereoscope
Inventor: KANEDA KEIJI
IPC: A61B1/00
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To easily obtain an image with a stereoscopic feeling by constituting a pair of image fibers so that the number of pixels thereof are naturally equal but the diameters of the pixel transmission parts thereof are mutually different. SOLUTION: A pair of image fibers 10 and 12 is constituted so that the number of pixels are mutually equal but the diameters of the pixel transmission parts are mutually different. That means, the diameter of the pixel transmission part of the fiber 10 is typically formed to be about 0.08-0.8mm and that of the pixel transmission part of the fiber 12 is formed to be about 0.1-1.0mm. Then, relative difference between them is set to be 5-20%, preferably, about 10%. Besides, the fused quartz based fiber is used as the fibers 10 and 12, for example. Then, the number of pixels is equally about 1600-50000. When they are constituted in such a way, the images whose sizes are different by 5-20%, preferably, 10% are formed on the left eye and the right eye even when a distance between the tip of a rod lens and an object to be observed is apart.  As the result, the object to be observed can be viewed with the stereoscopic feeling.
