The effect of total reflection on sensitivity of hybrid current fiber sensors
[in Chinese], and [in Chinese]

In hybrid current fiber sensors operating on the Faraday effect, reflection ig often used for changing the propagating direction of light to increase the effective optical path and to make the structure of the sensos compact. But the reflection changes the polarization of light, and consequently have an effect on the sensor's sensitivity. In this paper, Jones matrix method is used to derive the propagating characteristics of the sensor. The effect of reflection on sensor's sansitivity has been analysed and the results obtained agree with experimental data..

A digital speckle pattern interferometry system for automatic measurement of deformations of a diffuse object is presented by using phase-stepping and digital signal processing technique. Computer is utilized to take data and calculate phase without an intermediate recording step. Phase frings are produced instead of speckle correlation frings. Noise data points caused by randomness of the speckle are removed by digital signal processing. Two experimental results for the measurement of in-plane and off-plane deformations are presented..
