A fiber ring expansion coefficient and simple measurement method of reinforcing material

The present invention provides an optical fiber ring expansion coefficient and easy framework material measuring method, a measuring device for the artificial marble base platen, a suitable number of fixed displacement DRO bracket mounted thereon, and to measure optical fiber ring backbone material changes with temperature the amount of displacement. Support relative to the mounting base, ensure the required degree position corresponding to perpendicularity, parallelism, etc., and the base connected to the solid and reliable. Linear expansion coefficient of the material was measured using the above-described embodiment, although the measurement accuracy is not very high, but the shape is not particularly required for the material to be measured, the quick and easy measurement of fiber ring backbone expansion coefficient and a material line can be achieved.
