Abstract: An all-optical fiber sensor apparatus includes a light source and an in-line fiber polarizer that polarizes light received from the light source. The in-line fiber polarizer outputs light in a first polarization state which is directed to a polarization-maintaining fiber. After receiving the light in a first polarization state, the polarization-maintaining fiber transmits the light such that the light exits as light in a second polarization state. During measurements, the polarization-maintaining fiber contacts a test sample. A compression device compresses the test sample. The compression device applies a time varying force to the test sample in which the force is sequentially increased. A polarimeter receives the light in a second polarization state and outputs polarization state data for the light in a second polarization state. Finally, a data processor is in communication with the polarimeter to receive and stores the polarization state data.
