用光纤迈克耳孙干涉仪测量折射率
Refractive Index Measurement by Optical Fiber Michelson Interferometer
摘要
对测量群折射率的白光干涉和光纤迈克耳孙;Michelson 干涉仪技术进行了改进。采用样品夹片和样品与探测光纤端面接触的方法,可以使群折射率的测量过程简单化。根据反射峰宽度的变化,可以调整样品反射界面与光纤的准直性,提高测量精度。
Abstract
An improved method using white-light interferometry and optical fiber Michelson interferometer to measure group refractive index is introduced.The measurement process is simplified when sandwiched sample is used and contacted with detecting fiber surface.The collimating between sample and the detecting fiber can be adjusted according to the change of the bandwidth of the reflective peak.
