Description
Technical field
The present invention relates to a kind of processing technique field of fiber grating, the method for a kind of specifically fiber grating and substrate bonding.
Background technology
Optical fiber is present main flow transmission medium; Therefore advantage such as have transmission frequency bandwidth, message capacity is big, loss is low, do not receive electromagnetic interference (EMI), optic cable diameter is little, in light weight, the starting material source is abundant is widely used in communication, TV, the data transmission network.
Sensing technology based on optical fiber has the unrivaled applicating superiority of other sensing technology, makes it bring into play more and more important effect aspect great infrastructure, Important Project structure and the high-risk project security monitoring.
Utilize the temperature measurement sensing system of optical fiber to be mainly used in petrochemical industry, electric power, building, industries such as colliery and traffic, its effect is that the monitoring of real time temperature is carried out in these important places.It can play and guarantee that industrial system equipment normally moves, and ensures that the safety of life and property plays important effect.
Classic method is used glue; Form sandwich construction between optical fiber, tackifier, the substrate three; Under the stressed situation of integral body, produce relative stress between every layer of structure, make and can not make as a whole mechanics property analysis and the force analysis of carrying out; Complicated creep occurs, finally influence the measuring accuracy and measurement accuracy of Fibre Optical Sensor; Or repeatability can't guarantee, in addition its deviation from origin degree up to 30%FS about, cause sensor can't obtain effective practical application; The fatal especially defective of creep for applying prestressed sensor is because creep causes the prestress that is applied to Fibre Optical Sensor originally slowly to be eliminated, till this sensor is ineffective fully.
Existing one piece of technical papers about the fiber grating adhesive approaches; Article is numbered 1004-924X (2009) 09-2069-07's and narrates in recent years in the fiber-optic grating sensor of online molding process " adopt "; Fiber grating has received very big concern at sensory field of optic fibre, increasingly is applied to strain temperature; Pressure is in the quasi-distributed measurement of physical quantitys such as acceleration.Yet the foveal reflex wavelength of fiber grating can drift about with the fluctuating of environment temperature and the change of stress, and grating wavelength is long more, and its reflectance spectrum hand Influence of Temperature is big more, and the out of true of the measurement result that causes thus can cause the deterioration of system performance.For example wavelength is the fiber grating of 1550nm, and the temperature drift in the time of-20-40 degree centigrade is about 0.7nm, and this is a fatal shortcoming for sensing.Therefore, be necessary the gold temperature of fiber grating is carried out temperature compensation.
In order to address this problem, some researchers propose the prestress mechanism based on two materials.For example G.W.Yoffe proposes to encapsulate with the metal material of two kinds of different heat expansion coefficients; People such as L.Yuan have also carried out same trial research; People such as Tsai have then proposed a kind of more accurately fine setting mechanism based on bimetallic material; The method that above-mentioned document relates to all need apply prestress to grating, and its package temperature compensation result is gratifying, but since when encapsulation adopt be point type bonding be threaded; Before bonding, must apply certain prestress; Cause bonding not firmly easily, or place creep makes the fiber grating long-time stability poor.Though the packaged type of bibliographical information does not need stress application in advance, needs metal cladding, the length of complex process and encapsulation is longer, and its temperature coefficient still has 0.1pm/ ℃.Document has adopted the thought of online moulding, through one deck air layer is set, grating has been carried out temperature compensation.Because these negative expansion method for packing can't measure strain, can only be used for communication field, be seated and think and this kind compensation method be used for Chang'an still needs are further perfect.
