Abstract: An improved passive optical range simulator device which can be used to test the ranging function of an optical radar ranger system having parallel beams leaving and entering. An adapter member provides for mechanical coupling and optical alignment of the simulator device with the ranger system. A focusing lens transforms parallel beams entering and leaving the ranger system into focused beams entering and leaving one end of a coil of optical fiber having a mirror at its opposite end to act as an optical delay medium. A primary tilted-glass-element optical attenuator limits optical energy allowed to reach the optical fiber entrance face, while defecting first surface reflection away from ranger system input. A removable attenuator assembly having oppositely-tilted flat glass elements at the fiber entrance face permits, by substitution, fine adjustment of beam attenuation. An X-Y-Z translation assembly for the fiber entrance face, together with a light source at the opposite end of the fiber, provides for proper alignment with the focused beams.

Abstract: A fiber optic interface junction assembly in which an unsheathed end portion of a floating buffer optical fiber is held in perpendicular biased abutment with an optical interface surface by a constrained terminator for such end portion and a continuous coiled portion of the buffered fiber. The interface surface may be active, as in light transmission to the abutting fiber end, or passive, as in reflection of light backwardly into the fiber at such end, according to the particular function needed to be served by the assembly. The end of the optical fiber abutting the interface surface is made square to the fiber axis by cleaving, for efficient optical coupling with such surface, and chamber means are provided for retention of index matching fluid in encirclement of such end, for added assurance of coupling efficiency and protection against contamination by light-obstructing foreign substances that may be present in the surrounding environment.
