Abstract：
 The present invention is multi-parameter comprehensive fiber grating sensing experiment instrument as one kind of physical and detection technology teaching instrument. The instrument includes measuring unit, sensing unit and fiber coupling link. The sensing unit includes frame, equal-thickness isosceles triangle cantilever beam fixed inside the frame, gravitational pendulum fixed to the bottom of the cantilever beam, two fiber gratings with the same parameters adhered symmetrically on two sides of the cantilever beam, micro displacement meter fixed horizontally to one side of the frame, micro obliquity meter fixed vertically on the other side of the frame and electromagnetic coil fixed inside the bottom of the frame. The instrument may be used in detecting current, obliquity, vibration and displacement, performing various fiber experiment, etc. and is suitable for use in relevant teaching experiments.
