Abstract
A fiber optic system for permitting viewing of any of a plurality of selectable remote scenes in hostile environments by direct image transmission to the observer outside of the environment of the scenes. An optical image of each scene is transmitted by separate fiber optic bundles to an optical selector system which redirects the transmitted image through a single bundle where the image is presented in a form for viewing by the observer. The system is particularly useful in troublesome environments such as are encountered in the high pressures outside vessels or noise radiation sources where conventional television viewing systems can be used only with special insulation or containment.
