Description

Technical Field

[0001] The invention relates to the technical field of physical deposition simulation, and in particular to a laser grating coordinate device used for deposition simulation experiments. Background Art

[0002] During and after the experiment, the sediments need to be observed in the same coordinate system in order to reconstruct the evolution of the sediments. During the simulation experiment in the sediments, it is necessary to take pictures and describe the typical sedimentary phenomena in the coordinate system.

[0003] The existing method of pulling ropes in the long and short axis directions of the simulation pool as coordinates is intuitive, but dragging the ropes can easily damage the surface of the sediment, and the ropes are easily deformed and cannot fit the surface of the sediment, resulting in large errors when conducting more detailed observations.

[0004] However, drawing lines on the surface of the sediment as coordinates destroys the surface features of the sediment. It is only applicable to smaller simulation pools. If the simulation pool is large, it is difficult to draw lines while standing on the pier. Moreover, lines can only be drawn after the experiment is over. Lines cannot be drawn during the experiment, and a coordinate system cannot be provided for observations during the experiment.
