METHOD FOR DETERMINING A CONDITION OF AGING FOR OPTICAL FIBER GRATING

摘要

The present invention provides a method for determining a condition of aging for an optical fiber grating. This method comprises a step of setting the aged deterioration curve of the optical fiber grating as a form proportional to t-n, where t represents time, and n represents a parameter dependent on temperature; and a step of determining the condition of the aging according to the aged deterioration curve.
