Abstract
In an eyepiece or photographing device for a fiberscope having a bundle of optical fibers for image transmission and an eyepiece or photographing optical system for observing or photographing the exit end face of the bundle, an optical monocrystalline plate having a double refraction characteristic is disposed to obtain separate images from the images at the ends of the various fibers. The result is an image in which high frequency spatial interference, such as moire fringing, is eliminated. The monocrystalline plate may further be provided with a low-pass filter characteristic.
