| Abstract: | A scheme for extending measurement range of the angular displacement sensor is presented.The measurement range of the sensor can be extended without reducing measurement resolution by using multi receiving optical units,and the sensor meet some practical applications with high measurement resolution and large measurement range.The results show that its measurement range is 360 " and resolution are 0.004 " and 0.005 " respectively. |
