Abstract:
A select trigger or detonation system using fiber optics, comprising:an optical source for providing an optical signal having at least one triggering or detonation wavelength (.lambda..sub.1, .lambda..sub.2, . . . , .lambda..sub.n);an optical fiber having one or more fiber Bragg Gratings with one or more associated wavelengths (.lambda..sub.1, .lambda..sub.2, . . . , .lambda..sub.n), the one or more fiber Bragg Gratings being responsive to the optical signal, for providing one or more fiber Bragg Grating optical trigger or detonation signals;one or more optical couplers, each responsive to the one or more fiber Bragg Grating optical trigger or detonation signals, for providing a respective coupled fiber Bragg Grating optical trigger or detonation signal; andone or more light trigger or detonation means, each responsive to the respective coupled fiber Bragg Grating optical trigger or detonation signal, each selectively triggering or detonating when a respective triggering or detonation wavelength (.lambda..sub.1, .lambda..sub.2, . . . , .lambda..sub.n) of the optical signal corresponds to a respective associated wavelength (.lambda..sub.1, .lambda..sub.2, . . . , .lambda..sub.n) of the one or more fiber Bragg Gratings.
