中文摘要	The existing so-called "dual polarization competition laser displacement sensor" applies a cat's eye resonator. The resonator could be disarranged when the cat's eye reflector (CER) swings slightly with the rod of the slide rail in measuring the procedure and droops due to its deadweight in long-time operation. This influences the stability of the sensor significantly. In this paper, a novel cat's eye folded resonator was built, based on which our system named "folded resonator-dual polarization competition laser displacement sensor" was set up. It has a high resolution of lambda/16 (39.6nm) and large measurement range of up to 17mm. The misalignment sensitivities of traditional cat's eye resonator and the folded one are both analyzed; and comprehensive experiments are carried out, through which a conclusion can be drawn out that the maximal adjusting angle and the maximal cross displacement of the CER in folded resonator are both about 5 times of those in cat's eye cavity. Furthermore, the measurement results from this new sensor prove its high stability. (c) 2006 Elsevier B.V. All rights reserved.
