| Abstract: | In this paper,the measurement of tide variation of the earth has been studied by using laser
double beam Interference method.We have discussed the measuring principle and precision.The
results show that the precision is of 0.006 m at =6 328,length 25 m by modulating and counting of
interferogram.So the mathod may be used to measure the tide variation of the earth in tunnel. |
