Interferometer for Endface Geometry Parameter Measurement of Optical Fiber Connector

An interferometer for measuring endface geometry parameters of optical fiber connector with high accuracy is reported. The endface topography of the optical fiber connector and the coordinates of the center of the fiber core are obtained. The endface geometry parameters, which have a great effect on the performance of optical fiber connector, are calculated. The interferometer is compact and easy to use. It can be used to measure the endface geometry parameters of physical contact, angle physical contact and other kinds of optical fiber connector. Actual measurements show that the interferometer has a good repeatability. The measurement accuracy of the interferometer is at the same level as that of the Dorc's ZX-1 mini PMS interferometer and the Norland's NC3000 interferometer. The interferometer has passed the test performed by the National Center of Measurement and Test for East China.
