    Abstract: A fiber optic polarimetric strain sensor and associated data acquisition system capable of all-optical measurements of physical parameters, such as structural strain, gas and liquid pressure, acceleration and vibration, gas and liquid flow rate, and force without fire and explosion hazards associated with conventional strain gage technologies, such as resistance foil strain gages. The polarimetric strain sensor houses a sensitive element—a length of single mode optic fiber—changing polarization of a single-mode optical signal running in the fiber under some mechanical affects, specifically twisting and radial compressing. A linearly-polarized light passes the sensor, which causes polarization deviation of the light, particularly, polarization plane rotation under mentioned above twisting or compressive stresses applied to a sensitive element of the sensor. A multi-channel time division multiplexing data acquisition system that includes polarization analyzer indicates the polarization state deviation caused by the strain, so allow measuring the parameters. The invention may be embodied for measurements of any phenomenon that can be transformed in stress on an optical fiber.

Here, amplitude of a single-mode light passing the gage experiences variation under this specific mechanical bending applied to the sensitive element of the gage. A multi-channel time-division multiplexing data collecting system that includes another object of this invention—a single-mode fiber-optic switch. The invention may be embodied to measure any phenomenon that can be converted into the bending of a single-mode optical fiber.
