  • Patent number: 10859411
    Abstract: Fiber optic sensors for distributed monitoring of physical parameters along a fiber optic cable are disclosed. A sensor comprises a fiber optic cable mounted to a flexible member disposed in a sensor housing body. The flexible member is coupled to the body and to a bladder in the body. The bladder is exposed to an immediate external environment to the sensor through a port in the body so that changes in pressure or liquid level in the environment cause changes to the size of the bladder, which in turn change the shape of the flexible body to impart mechanical strain on the cable. The cable may be inscribed by fiber Bragg gratings. Changes in spectra may be analyzed to measure the physical parameters. Simultaneous measurement of temperature, liquid and gas pressure, vibration, mechanical strain, liquid level, liquid flow rate, and deformation in a distributed fashion generates a 3-D environmental map.
