| 摘 要： | 光纤布喇格光栅触发式测头是一种新型测头. 传感信号解调是光纤光栅作为敏感元件应用于测头的关键技术之一. 在光功率与波长漂移量函数关系的基础上，借助双频激光干涉仪、纳米级的微动平台对试制的测头进行FBG自解调实验. 结果表明，研制的测头分辨率达到100nm，验证了光纤布喇格光栅应用于触发式测头的可行性.

| Abstract: | The touch trigger probe based on fiber Bragg gratings is a newly developed probe.With a sensing element used in a three-dimensional probe,sensor signal demodulation is a key technique.By means of the dual-frequency laser interferometer and nano-level stage,the sampling probe is tested using a self-demodulation approach based on the functional relations between optical power and wavelength shift.Resolution of more than 100 nm can be achieved from the analysis of experimental data on a developed probe.Further... |
