Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and working principle.
[0021] combine figure 2 As shown, the test system consists of an ultra-precise synchronous motion linkage device system 5, a graphene reference sample detection device 1 and a graphene standard sample mobile workbench 3, a test object detection device 2 and a test object mobile workbench 4, signal analysis The control system consists of 8 components. In the scanning measurement, the graphene and the object to be measured are placed on their respective workbenches, and placed under the graphene reference sample detection device 1 and the object to be measured detection device 2 respectively.
[0022] The graphene standard sample mobile workbench 3 and the object-to-be-measured mobile workbench 4 are linked through an ultra-precise synchronous motion linkage device system 5, and there is a sub-nanometer quantitative displacement function...
