the dynamic stiffness of the slideway-bed of a laser interferometric length measurement system will effect on its measurement accuracy severely. However so far
it is not easy to estimate the degree of its effects in advance
or to give certain conpensation just due to the lack of some proper methods to test. In this paper
we introdued a simple but very effective method of using two laser interferometers by which we tested the 2-D dynamic stiffness of the three-layer type of slideway-bed of a laser interferometric length measurement system. The principle of that method and the experimental arrangements are described
