An integrated fiber interferometry interrogator for generating superimposed waves is disclosed. The system is optimized for efficiency and vibration attenuation. The system comprises an optical light source for generating a first signal, a first signal splitter which splits the first signal into a reference signal and an interrogation signal, optical modulators for modulating the signals, a fiber coupler connected to a fiber under test, an isolator, a circulator with a plurality of connections for directing the signals, a signal mixer for mixing the signals into superimposed waves, and photo diodes for receiving the superimposed waves.

Noise management for optical time delay interferometry

A modular fiber optic interferometry control system and method for extracting information from superimposed waves is disclosed. The system comprises a first module for converting a radio frequency input to a multiplexed binary data stream, a second module for correlating a pseudo random number (PRN) reference with a received PRN code modulated backscattered signal, and a third module comprising control logic. In some embodiments the system further comprises one or more of a fourth module for generating a power stream, a fifth module for event interrogation, and a sixth module for noise reduction.

Real-time fiber optic interferometry controller

Systems and methods are disclosed for dynamic addressing of optical fiber sensors in fiber optic interferometry systems. Events that occur along the optical fiber span have defining attributes such as location along the optical fiber span, type, magnitude, time of occurrence, and duration. The event attributes may be used to dynamically form a unique address that fully defines and identifies the event. Other information, such as the corresponding identifier for one or more of the optical fiber span and the corresponding fiber optic interrogator may be included as part of the unique address.
