Implementation and Survivability of Fiber Optic Sensing in Body Armor

Fiber Bragg grating sensors are configured to survive behind body armor during a ballistic impact. The keys that enable the fiber Bragg grating to survive the impact are allowing the optical fiber to slip, using draw tower gratings, using Ormocer as the optical fiber coating, and embedding the optical fiber in a silicone mat. The fiber Bragg grating sensor was tested in ballistic impact with a velocity of 430 m/s.
