FIBER BRAGG GRATING SENSOR AND SYSTEM OF MEASURING TEMPERATURE AND STRAIN USING THE SAME

摘要

PURPOSE: An optical fiber lattice sensor and a system for measuring a temperature/strain are provided to facilitate to manufacture due to a simple structure and the precision of measuring a strain and temperature can be enhanced. CONSTITUTION: An optical fiber lattice sensor(40) comprises an optical fiber(50), a first group lattice portion(60), and a second group lattice portion. The fist group lattice portion comprises a first lattice unit(60) and second lattice unit(70). The second lattice unit is spaced from the first lattice unit. The second group lattice portion comprises a third lattice unit(80).
