Fiber optic seal
First Claim
1. Fiber optic seal apparatus comprising a block, first and second pathways crossed within the block, the pathways having openings in spaced relationship on facial areas of the block, bundle holding means connected to the block for holding an optic fiber bundle end inserted in each pathway with portions of the fibers near one end of the bundle threaded between portions of the fibers near the opposite end of the bundle in random arrangement within the block with a medial portion of the bundle passing through an object to be sealed.

Abstract
A fiber optic bundle is placed through an object to be sealed. Ends of the fibers are spread and threaded through one another in a random dispersion, disorienting the fibers. Randomly reoriented ends are regathered and clamped. A moveable reticle at a light input termini of the fibers creates unique identifiable patterns at the output end of the fibers.

- 17. Fiber optic seal apparatus comprising a fiber optic bundle having a plurality of coextensive and coterminal optical fibers held together with a medial portion for engaging an object to be sealed, with portions of the fibers near one end of the bundle threaded between portions of the fibers near the opposite end of the bundle in random arrangement, means to separately hold first and second remote termini of the bundle of fibers, means for introducing light into the first termini, and means for observing light in the second termini, and means for predeterminately interrupting light in the first termini and means for recording locus of fiber ends in the second termini showing characteristics of interrupted light.

20. Fiber optic seal apparatus comprising a fiber optic bundle having a plurality of fibers with a medial portion fof engaging an object to be sealed and with end portions having randomly interspersed fibers, with portions of fibers in one end of the bundle interspersed among portions of fibers near an opposite end of the bundle, means for holding termini of the fibers and means for illuminating some of the termini and means for receiving illumination of other of the termini, reticle means for interposing masking between the illuminating means and said some of the termini for selectively partially preventing illumination, and means for moving the reticle means for changing the masking.
