The fiber optic relay system decribed samples the wavefront radiated from the image to be relayed so that resolution is limited only by wavelength and the diameter of the entire fiber bundle at its ends. Consequently, the system can be used to relay or to combine images in a diffraction limited system as, for example, in a large multiple mirror telescope. The fiber bundle consists of approximately 7000 single mode optical fibers whose optical paths have each been adjusted equal to Nλ±1/20λ, where λ is the wavelength of interest and N is less than 10. Total fiber area is approximately 10 percent of the available spherical area so that wavefronts from a number of bundles may be combined. Diffraction ray trace data is presented for a specific relay system which models the output from a Michelson stellar interferometer.
