Abstract

It is very significant to develop the fiber-optic telescope that makes use of the large cross-section (i.e., large information) image-transmitting bundle and to realize the system combined 'rigid' with 'soft', in order to achieve the observation of remote objects in some difficult conditions. This paper discusses the key technical problems by which simpler structure, higher performance indices (magnification, field of view) of systems, finer resolution and better results of observation are realized under the condition of the definite image-transmitting bundle. These problems are: to choose and use high performance LCSITB; to select a reasonable eyepiece to restrain the mosaic pattern of the image; to make use of the objective lens that has long focal distance and large aperture to obtain optimal coupling between the objective lens and LCSITB and to obtain the higher resolution and sufficient brightness of the image; and to select the simplest erecting system. Using the fiber-optic telescope which is designed and developed, it is observed and photos show the remote objects from about one kilometer and good results are achieved.
