| Zusammenfassung: | The present invention relates to a continuous input method for sequential UV-writing fiber Bragg grating by a real-time position monitoring characterized by applying lateral diffraction interference method for determining optical fiber grating of every positioning point and relative phase of inputting interference light beam and then inputting it seriatim. The present method is capable of increasing production precision in manufacturing a longer optical fiber grating having a more complicated structure via reducing or preventing accumulated errors caused by long scanning of monitoring optical fiber positioning, or via method of manufacturing referential fiber Bragg grating according to similar configurations. |
