The invention discloses a method of compensating fiber grating temperature coefficient with encapsulation cannula which possesses negative temperature coefficient. A material which does not possess negative temperature coefficient is used to produce encapsulation cannula with tiny negative heat expansion coefficient by special process; it can completely compensate the wavelength shift generated by change of temperature. The encapsulation cannula encapsulates the fiber grating quickly under the high temperature to produce fiber grating which is not sensitive to temperature and possesses high heat stability, and it is high and low temperature circle aged for multiple times. The invention is simple, cost is low, more important is that the temperature performance is well, the temperature coefficient of fiber grating can achieve 0.0005nm/DEG C under the circumstance of -10DEG C to 60DEG C, and it possesses perfect long time temperature property. The column of the fiber grating encapsulatedis ...
