A method and apparatus for detecting a change in an internal configuration of a platform. The apparatus comprises a number of optical fibers and a detector. The number of optical fibers extends through a platform. The detector is configured to detect a change in a manner in which light propagates through the number of optical fibers when an internal configuration of the platform changes.

1. An apparatus comprising: a number of optical fibers extending through a platform;a detector configured to detect a change to an internal configuration of the platform by determining a change in a manner in which light propagates through the number of optical fibers to identify a bending of the platform; anda navigation system configured to account for the bending of the platform to avoid unnecessary corrections to the direction in which the platform travels. 2. The apparatus of claim 1, wherein the detector is further configured to transmit information about the change in the manner in which the light propagates through the number of optical fibers to a navigation system for the platform. 3. The apparatus of claim 1, wherein the change in the internal configuration of the platform is selected from at least one of a bending of the platform and a twisting of the platform. 4. The apparatus of claim 1, wherein the change in the manner in which the light propagates through the number of optical fibers is selected from at least one of a change in propagation time and a change in phase. 5. The apparatus of claim 1, wherein the number of optical fibers is formed within a fuselage of the platform. 6. The apparatus of claim 1, wherein the number of optical fibers is attached to the platform. 7. The apparatus of claim 1, wherein the platform is a rocket and wherein the number of optical fibers is configured to extend at least one of longitudinally along a length of the rocket, helically around a diameter of the rocket, and circumferentially around the diameter of the rocket. 8. The apparatus of claim 1 further comprising: a light source configured to send the light through the number of optical fibers. 9. The apparatus of claim 8, wherein the light source is configured to transmit pulses of coherent light. 10. The apparatus of claim 8, wherein the light source is configured to send pulses of the light through the number of optical fibers. 11. The apparatus of claim 8, wherein the light source is configured to send the light using a number of wavelengths. 12. The apparatus of claim 1, wherein a number of Bragg gratings is present in the number of optical fibers. 13. The apparatus of claim 12, wherein the number of Bragg gratings is in a number of locations in the number of optical fibers, wherein the number of locations defines a number of lengths along which the change in the internal configuration of the platform is monitored. 14. The apparatus of claim 1 further comprising: a number of devices configured to transmit information used to operate the platform using the number of optical fibers. 15. The apparatus of claim 1, wherein the platform is selected from one of a mobile platform, a stationary platform, a land-based structure, an aquatic-based structure, a space-based structure, a launch vehicle, a missile, a rocket, a surface ship, a tank, a personnel carrier, a train, a spacecraft, a space station, a satellite, a submarine, an automobile, a power plant, a bridge, a dam, a manufacturing facility, and a building. 16. The apparatus of claim 1 further comprising: the detector configured to generate an alert based on a bending magnitude and rate of bend in pitch and yaw axes of the platform; anda navigation system configured to use the alert to account for the change to the internal configuration of the platform to reduce adjustments made to a direction in which the platform changes and reduce corrections and over-corrections. 17. A method for detecting a change in an internal configuration of a platform, the method comprising: sending light through a number of optical fibers extending through the platform;detecting a deformation of the platform by determining a change in a manner in which the light propagates through the number of optical fibers when the internal configuration of the platform changes to identify a bending of the platform; andaccounting for the bending of the platform to avoid unnecessary corrections to the direction in which the platform travels. 18. The method of claim 17, wherein a detector is configured to send information about the change in the manner in which the light propagates through the number of optical fibers to a navigation system for the platform. 19. The method of claim 17, wherein the change in the internal configuration of the platform is selected from at least one of a bending of the platform and a twisting of the platform. 20. The method of claim 17, wherein the change in the manner in which the light propagates through the number of optical fibers is selected from at least one of a change in propagation time and a change in phase. 21. The method of claim 17, wherein a number of Bragg gratings is in a number of locations in the number of optical fibers, wherein the number of locations defines a number of lengths along which the change in the internal configuration of the platform is monitored.
