Description

technical field [0001] The invention relates to the field of grating ruler marking, in particular to a portable grating ruler main scale marking device and a marking method thereof. Background technique [0002] At present, the technology of using grating ruler for displacement measurement has become increasingly mature, and the displacement measurement based on grating ruler not only has high measurement resolution, but also reduces the deformation of the measured system because the grating ruler can perform full closed-loop control on the system under test. The error caused by the measurement accuracy is high, and it plays an important role in the development of production and manufacturing industries. [0003] At present, there are two main methods to describe the main scale of the grating ruler, namely the mechanical writing method and the laser holographic method. For the mechanical profiling method, at present, the planer type developed by Roland is mostly used, that ...

Problems solved by technology

However, the price of a good light source is quite expensive, and there are problems such as rough edges of the grid line in the laser holography method.

[0005] Moreover, the equipment used in these two lithography technologies is expensive, complex in structure, and bulky. When disassembling or moving and re-drawing, it takes many attempts to debug the equipment to a normal working state, which consumes a lot of manpower and material resources.
