Problems solved by technology

[0007] The technology of micro-area laser etching has been used in optical disc recording for decades, but the known laser storage substrates such as optical discs are plastic or artificial semiconductor flakes, not rock substrates, so rock substrates have not yet been used as optical storage media. report

Embodiment 1

[0027] Embodiment 1: rock polarized sheet substrate storage medium, and its manufacturing method and application:

[0028] The base material of the polarized rock sheet includes a crystalline rock or mineral sheet with a thickness of 5-1000 μm, and polarizers detachably fixed on both sides of the sheet; the crystalline rock cannot be opaque mineral content higher than 35% Rocks must not have a homogeneous mineral content higher than 80%, clay mineral content higher than 5%, rocks with a solubility of all rock components greater than or equal to 0.1g, and minerals with a Mohs hardness less than or equal to 5 and a mineral content of more than 50. % of rocks; the reason why the thickness range varies greatly is that when the same interference color of the same order is present, the thickness (d) of the mineral flakes is inversely correlated with the birefringence (DR) of the mineral, and the optical path difference R'=d× DR, which is why the color of carbonate minerals (DR≈0.2) ...

Embodiment 2

[0030] Example 2: The use of rock polarizing sheet substrates in aircraft black boxes:

[0031] The black box (201) at least includes a rock polarized sheet substrate storage medium (70) and a laser system, and the laser system includes a controller (208), a laser source (202), a laser writer (203), a laser positioner (206 ), laser reader (205), optical fiber (207); laser writer (203), laser locator (206), laser reader (205) are wrapped in a black box, and the laser source passes through optical fiber (207 ) and the laser writer (203), laser locator (206), and laser reader (205), realize optical path connection and electrical connection, and the rock polarized sheet substrate storage medium (70) is movably fixed on the slide The rail (209), the slide rail (209) are fixed and wrapped inside the black box, and the vacuum chamber or the transparent interlayer (204) surrounds the substrate of the polarized rock sheet; The frequency of the laser system is constant, the laser write...

Embodiment 3

[0032] Embodiment 3: The application of rock polarizing thin slice substrate to data backup on the surface of the moon:

[0033] The test data of the lunar rover is backed up by etching the substrate of the polarized sheet of the rock with a laser beam spot. On the surface of the moon, the rock polarized sheet substrate storage medium is manufactured according to the method described in Example 1, which can be carried by the earth’s launch mission, or anorthosite can be selected locally on the moon, prepared by polishing with lunar soil powder, and can be disassembled Fixed to space probes. When the pre-selected area of ​​the storage medium of the polarized rock sheet substrate is ablated, in order to make the data storage capacity per unit area large enough, the laser beam spot diameter during the laser ablation process is not greater than 50 μm, and the energy range of the laser beam spot is not greater than 6J. cm -2 . During the process of data transmission and analysis...

Abstract

The invention provides a rock polarizing sheet base material storage medium and a manufacturing method and application thereof. The rock polarizing sheet base material storage medium comprises a storage medium and jewelry which are manufactured by using gem and jade leftover materials and part of rock specimen sheets in a geology research process as raw materials, and a manufacturing method and application thereof. Rotation discoloration of jewelry in polarized light is achieved through the first polaroid, the fixing layer, the bearing, the rock slice, the second polaroid and other components,data storage is achieved through a laser etching method, and comprehensive utilization of rock leftover materials is achieved. Moreover, no two identical rocks exist in the world, so that the productprovided by the invention cannot be counterfeited; the polarized jewelry disclosed by the invention can be used for identity recognition without additionally implanting electronic equipment into thejewelry, and an unexpected identity recognition effect is generated on the basis of the decoration effect of the jewelry. When used as a black box or a space detector storage medium, the storage medium can be more resistant to high temperature, corrosion and radiation than a conventional storage medium.

Description

technical field [0001] The present invention relates to an extreme environment storage medium, and its related manufacturing method and application. Specifically, it uses polycrystalline rock flakes to rotate under polarized light to achieve changing color combinations, and utilizes rock mineral particles Durability enables storage of data in extreme environments, and rock non-reproducibility enables methods of identifying media. Background technique [0002] When different minerals are ground into thin slices of the same thickness, the characteristics of interference color and extinction angle are generally different, and when ground into thin slices with a thickness of about 0.03mm, most minerals will become transparent. Therefore, to study and identify rocks or transparent minerals under a polarizing microscope, it is necessary to grind a large number of rock mineral specimens into thin slices for observation. However, geological research institutions have to eliminate a...
