ABSTRACT:
An optical fiber telescope is disclosed as including an optical train having a plurality of tapered optical fibers arranged in a plurality of cascading stages. A collecting stage provides the aperture for the telescope and has an output for transmitting light to a terminal stage located downstream of the collecting stage. The input of the terminal stage is optically coupled to the output of the collecting stage and provides the optical output for the telescope according to the invention. Further disclosed is a telescope-based tracking system incorporating tapered optical fiber telescopes in accordance with the present invention. Output light from each telescope of the system is received by a detecting device which generates a signal representative of information contained in the received light. This signal is applied to a determining device which, for example, determines the position of the object.
