Tamper-proof container
First Claim
1. A tamper detection system, comprising:
- a first rectangular liner sheet having a first area and defining a fiber-optic path extending across at least a portion of the first area, the first liner sheet including two parallel foldable regions, each foldable region extending laterally across the smaller dimension of the rectangular liner sheet;
a second liner sheet having a second area and defining a fiber-optic path extending across at least a portion of the second area;
a third rectangular liner sheet having a third area and defining a fiber-optic path extending across at least a portion of the third area, the third liner sheet including a foldable region extending laterally across the small dimension of the rectangular liner sheet, thereby defining a hingable portion of the third liner sheet;
a coupler interconnecting the fiber-optic path of the first liner sheet and the fiber-optic path of the second liner sheet; and
a coupler interconnecting the fiber-optic path of the first liner sheet and the fiber-optic path of the third liner sheet.

Abstract
A sheet includes an optical fiber extending across at least a portion of its surface to detect a breach or nuclear radiation. The sheet can line at least a portion of a container or a fence. A breach of the sheet or radiation within or near the sheet reduces optical transmissibility of the fiber. The fiber integrates the radiation over time and/or over the length and volumetric mass of the fiber, making the fiber sensitive to even low-level radiation. The optical fiber is monitored for a change in its transmissibility. A reduction in the transmissibility, such as to below a threshold, can trigger an alarm, such as an annunciator, or send a message that includes information about the time or the container'"'"'s contents or location when the breach or radiation is detected to a central location, such as a ship'"'"'s control room or port notification system.
