ABSTRACT

An FBG curvature sensing test device and a test method thereof are provided.
The test device includes a test platform, an FBG demodulator, and a computer.
The test platform includes an optical plate and two constraint components,
test pieces are connected between two constraint components, where the
constraint component includes an X-axis displacement stage, a Z-axis rotation
stage and a fixture, the X-axis displacement stage is connected to the optical
plate and can move along an X-axis direction, one end of the Z-axis rotation
stage is connected to the X-axis displacement stage, and the other end of the
Z-axis rotation stage is connected to the fixture; the FBG demodulator is
configured to convert an optical signal of a wavelength change monitored by
the FBG test line based on the deformation of the test piece into an
electrical signal; the computer is coupled to the FBG demodulator.
