Description
Technical Field
The invention relates to an extreme environment storage medium, a manufacturing method and application related to the medium, in particular to a method for realizing color combination change by utilizing rotation of polycrystalline rock slices under polarized light, realizing extreme environment storage data by utilizing durability of mineral particles of rocks and realizing identification media by utilizing irreproducibility of the rocks.
Disclosure of Invention
When different minerals are ground into thin sheets of the same thickness, the interference color and extinction angle characteristics are generally different, and when ground into thin sheets of about 0.03mm thickness, most minerals will become transparent. Therefore, the study and identification of rock or transparent minerals under a polarizing microscope requires the examination of a large number of rock mineral specimens which are ground into thin slices. However, geological research institutions need to eliminate a large amount of rock polished thin sheets (more than 10 ten thousand sheets per institution on average, and each area is 6-10 square centimeters) stored in a large amount every year, and direct discarding of the rock polished thin sheets causes garbage and also brings the risk of scratching people by polished thin glass. Moreover, these optical sheets are produced at a cost of about 30 to 40 dollars per sheet, and if discarded after use, they are economically very wasteful. If the glass is recycled, rock is added in the preparation process, which is equivalent to doping impurities into the glass, and the glass is difficult to be directly recycled by a known method of recycling and remilling, so that a new utilization way is needed for the rock optical sheet.
According to the known crystal optical knowledge, if a transparent rock slice of a light-induced inhomogeneous body is placed between two orthogonal polaroids, the optical axis section is oblique, one of the elliptical radiuses of the light-induced inhomogeneous body is oblique to the polarization direction of the lower polaroid, the polarized light generates double refraction after passing through the rock slice and is decomposed into 2 polarized lights, and the 2 polarized lights generate interference phenomenon after passing through the upper polaroid, and finally a certain color is displayed, namely the interference color. The observation of the seven-color interference color must be under a white light source, because white light is a mixture of 7 kinds of monochromatic light with different wavelengths λ, and for a certain optical path difference R, one kind of monochromatic light can form a black band around the optical path difference of R =2n (λ/2), while the other kind of monochromatic light is not necessarily dark. Each monochromatic light is superposed, strengthened and offset weakened according to different rules, so that the 7 monochromatic lights corresponding to the optical path difference are mixed together to form a mixed color, namely a seven-color interference color.
In practice, partial rocks in the geological research process, and stones including but not limited to gabbro, komattes, durigone, jadeite, Hetian jade, Dushan jade, diopside, common spherulite and the like or leftover materials in the jewelry jade processing process are ground into thin slices with the thickness of about 30-70 mu m, the thin slices are rotated under orthogonal polarization, most people can observe the fact that the crystalline thin slices are rotated under the orthogonal polarization to have colorful colors which are similar to the chanel colorful glass, and the interference color characteristics are different and almost irreproducible in each rock thin slice. Foreign magazines are known to contain some mineral micrographs as wallpaper materials, but no ornaments with the function of identification documents made of rock light sheets are searched in the prior art, and the market is not seen. The reference CN105825248B discloses a gemstone embedded with a near field communication chip for communication with an NFC enabled device, and the chip and the antenna of the jewelry disclosed in the reference CN207909149U on the jewelry body realize an identification function, both of which are implemented by implanting electronic devices such as the chip and the antenna in the jewelry, rather than a scheme of implementing a storage medium and an identification function by using uncopyable optical properties of the jewelry jade and even the rock itself.
Practice shows that the original interference color characteristics and crystal forms can still be kept after transparent early magma minerals such as olivine, pyroxene, plagioclase and the like, or artificial cubic zirconia and synthetic morusite are exposed to the high temperature of 1600 ℃ and 1000 ℃, and the temperature range is far beyond the suitable temperature of the current storage media such as optical disks, magnetic tapes, magnetic disks and the like; from the common knowledge, the temperature range of 1000-.
According to practical experience of papers published in international journals such as EPSL, GCA and the like, olivine, pyroxene and plagioclase are common minerals in the moon, and can be stored in the moon environment for more than 40 hundred million years. Considering that the sun wind particles and cosmic rays can damage the information stored in the memory, the arithmetic unit, the processor part and the electromagnetism of the lunar surface landing detector, cause program errors, obstruct the data processing and transmission processes and cause the embarrassment that data cannot be returned, for example, the rabbit lunar rover of Chang' e III encounters the dilemma. The technical scheme of using lunar surface minerals to carry out data backup by using local materials is not reported at present.
The technology of micro-area laser etching has been used for optical disc recording for decades, but the known laser storage substrate such as optical disc is plastic or artificial semiconductor sheet, not rock substrate, so the rock substrate has not been reported as optical storage medium. Considering that laser ablation techniques have been applied to rock testing, such as New Wave UP-213 nd fe-b permanent magnet-artificial yttrium aluminum garnet-quartz switch laser ablation system at the university of ta mania, australia, the laser system operates at a constant 10-50 hz pulse frequency, and the laser beam spot energy is typically in the range of 5-6 j.cm- 2. When the preselected area of the polished sample block is ablated, the diameter of the laser beam spot of the ablation analysis point can be adjusted to 20-150 mu m. The instrument, in addition to being able to be installed in a LA-ICP-MS system for testing the isotopic composition of minerals, is able to etch pit combinations representing recorded and imaged information in real time on mineral particles, although the device is too bulky and heavy to be suitable for a laser etching device for minerals, at least proving feasible for optical storage of laser etched mineral particles.
Disclosure of Invention
The invention aims to realize the storage medium and the identity recognition function by utilizing the irreproducibility of the optical properties of mineral particles in rocks, realize the comprehensive utilization of rock polarizing sheets, provide jewelry, extreme environment storage medium and identity recognition evidence manufactured by utilizing partial mineral rock sample sheets and gem and jade leftover materials in the geological research process, reduce the waste of the rock sample sheets, reduce the identity recognition cost and realize the backup of extreme environment data.
In order to achieve the purpose, the invention designs a rock polarization sheet substrate storage medium which comprises a crystalline rock or mineral sheet with the thickness of 5-1000 mu m and polarizers detachably fixed on two sides of the rock or mineral sheet; the crystalline rock cannot be rock with opaque mineral content higher than 35%, cannot have optical homogeneous mineral content higher than 80%, cannot have clay mineral content higher than 5%, cannot be rock with whole rock component solubility greater than or equal to 0.1g, and cannot be rock with mineral content of Mohs hardness less than or equal to 5 and greater than 50%; the reason why the thickness range is large is that when the same order interference color is presented, the thickness (d) of the mineral sheet is inversely related to the birefringence (DR) of the mineral, and the optical path difference R' = d × DR, which is why the color of the carbonate mineral (DR ≈ 0.2) with the thickness of 10 μm under orthogonal polarization is changed into the apatite (DR ≈ 0.002) which can present the same interference color only when the thickness is 1000 μm; when R' is less than or equal to 350nm and less than or equal to 2000nm, the crystalline flakes can be observed to rotate under orthogonal polarization to show a changing seven-color. As the practice finds, after olivine, pyroxene, plagioclase, artificial cubic zirconia and synthetic Mosang stone are exposed to the high temperature of 1600 ℃ of 1000-; as is known in the prior art, the temperature range of 1000-1600 ℃ is possibly the temperature experienced by a space detector and a black box of a crash aircraft, so the rock polarization sheet substrate storage medium is suitable for data backup of the space detector and the black box of the aircraft.
In a matching way, the invention provides a manufacturing method of the rock polarization sheet substrate storage medium, which comprises the following steps: selecting a rock slice raw material, wherein the rock slice raw material cannot contain opaque mineral content higher than 60%, optical homogeneous mineral content higher than 70%, clay mineral content higher than 5%, rock with whole rock component solubility higher than or equal to 0.1g, and mineral decomposed at the temperature below 1000 ℃ more than 5% (the physical properties of the minerals are known and refer to mineral dictionary or crystallography and mineralogy); step two: cutting transparent minerals or rocks into blank blocks with the length of more than 5mm, the width of more than 2mm and the thickness of no more than 2mm by using a slicer, a line cutter, a laser cutter or a water jet; step three: grinding and polishing one surface of the blank block by using at least one grinding material of carborundum or chromium oxide or corundum or pomegranate sand or diamond powder to obtain a first plane; step four: bonding the first plane with at least one of canadian gum, or polymethylmethacrylate, or methyl isocyanoacrylate, or frit glass, or polylactic acid, or epoxy resin to a carrier sheet, the carrier sheet being at least one of cubic zirconia, or synthetic diamond, or tempered glass, or fused quartz glass, or fused corundum glass; step five: after Canadian gum, or polymethyl methacrylate, or isocyano methyl acrylate, or sintered glass, or polylactic acid, or epoxy resin is dried and then is firmly bonded with a carrier sheet in a curing way, at least three diamond sheets with the same thickness, the thickness of which is 5-1000 mu m, are surrounded on the other side of the blank block at equal intervals and angles, and the other side of the blank block is ground until the thickness of the blank block meets the requirement of R' = d × DR and the thickness of which is more than or equal to 350nm and less than or equal to 2000nm, so that a second plane is obtained; step six: the second plane is adhered with the protection sheet. Thus, the rock polarizing sheet substrate storage medium is composed of the carrier sheet, the rock mineral sheet and the protective sheet. Due to the progress of advanced micro-area detection technologies such as an electron probe, a laser plasma mass spectrometer and the like, a plurality of scholars are better than rock and ore slices without protective plates for research and identification of a polarizing microscope at present, and obviously, the manufacturing of the slices omits the step six; and step six can be omitted in the manufacturing of the storage medium of the rock polarization sheet base material only when the rock polarization sheet mineral at least contains 75% of minerals with Mohs hardness more than or equal to 6 and melting points more than or equal to 1200 ℃, and the constraint ensures that the rock polarization sheet base material is not easy to wear or be damaged by high temperature.
In a further aspect, the present invention provides the use of a rock polarizer substrate for aircraft black box data storage:
the black box (201) at least comprises a rock polarization sheet substrate storage medium (70) and a laser system, wherein the laser system comprises a controller (208), a laser source (202), a laser writer (203), a laser positioner (206), a laser reader (205) and an optical fiber (207); the rock polarization sheet substrate storage medium (70) is movably fixed on a sliding rail (209), the sliding rail (209) is fixedly wrapped in the black box, and a vacuum chamber or a transparent interlayer (204) surrounds the rock polarization sheet substrate; the laser system works at a pulse frequency of 10-50 Hz, the frequency of the laser system is constant in the single route writing process, the laser writer (203) etches the rock polarization sheet substrate storage medium (70) with a laser beam spot, and the range of the beam spot energy is 0.2-6 J.cm–2(ii) a The preselected area of the rock polarization sheet base material storage medium (70) is selected by a laser locator and a laser reader through an extinction position and an interference color, and the information of the extinction position and the interference color can be manually set by a controller (208) through an instruction, or an electrical storage instruction, or a magnetic storage instruction, or an optical storage instruction to control a laser source (202), a laser writer (203), a laser locator (206) and a laser reader (205); when a preselected area of the rock polarization sheet substrate storage medium (70) is ablated, the diameter of a laser beam spot of an ablation analysis point is not more than 50 mu m. The laser system is uninterrupted in flight, and pit combinations representing recorded and imaged information can be etched on mineral particles in real time or on the surface of the rock polarizing sheet substrate storage medium (70) according to the vibration track of cabin sound waves. Rock polarizing sheet combining actual properties of mineralsThe material of the substrate storage medium (70) comprises at least 2 of olivine, pyroxene, agalmatolite, corundum, zircon, cubic zirconia, morganite, grapestone, natrolite, diaspore, tourmaline and quartz, because a plurality of etching processes are carried out, a plurality of same data are simultaneously backed up by laser etching on a carrier sheet attached to the substrate storage medium (70) of a thin sheet of a plurality of mineral particles or a rock polarization sheet, even if one substrate is damaged, each mineral is difficult to be completely damaged, and the plurality of backup processes are safer and more reliable; the characterization of the substrate as damaged also helps to determine the specific type of catastrophic event experienced by the media. For example, olivine and pyroxene cannot resist seawater corrosion for more than 5 years, and grapestite, natrolite and diaspore cannot resist high temperature of more than 200 ℃, so that electric properties of tourmaline and quartz change at high temperature, and cracks increase, so that when an event occurs, the change of minerals on the storage medium (70) of the rock polarization sheet substrate is helpful for judging the event experienced by the black box. When the accident occurs, the operation of the laser beam is reversed by recovering the rock polarizing sheet substrate storage medium (70) and etching traces by the laser beam spot thereon, and the pre-accident recording is resumed. Therefore, the invention provides a mineral storage medium suitable for extreme environments on the basis that rock polarization sheets can be uniquely identified and are difficult to copy, and performs multi-channel backup data by combining actual properties of minerals, so that even if a substrate is damaged, the method is helpful for judging the specific type of a disaster event experienced by the medium according to the damaged characteristic of the substrate. Techniques for inverting the sound by the operation of a laser beam are well known and have been used in the fields of laser-to-sound signal conversion and laser eavesdropping.
In a matching way, the invention provides the application of the rock polarization sheet substrate in data backup of a space detector, which comprises the following steps:
lunar vehicle test data was backed up in a manner that the laser beam spot etched rock polarizer substrates. On the surface of the moon, the rock polarization sheet substrate can be carried by earth launching missions, and can also be prepared by polishing lunar soil powder from a local material source in the moon and detachably fixed on a space detector. In order to allow a large amount of data storage per unit area when a preselected area of a block of polished samples is ablatedThe diameter of a laser beam spot in the laser ablation process is not more than 50 mu m, and the range of the energy of the laser beam spot is not more than 6J- 2. In the data transmission and analysis process, the laser system is continuously and electrically connected with the test system, the laser system receives the strength of the electric signal of the test system in real time, the electric signal of the test data is converted into the laser signal, the laser signal is etched on the lunar rock mineral according to the agreed format, the agreed format is determined by programming in advance, for example, different beam spot diameters represent different data types, the etching depth represents the numerical value, and pit combinations representing spectrum, image, component content and temperature information can be etched on the mineral particles in real time. In combination with the actual nature of the mineral, when the space probe is on the lunar surface, suitable rock-polarizing sheet substrates include at least 2 of plagioclase, olivine, aeolianite, enstatite, garnet, brewstone, tetrahedron, corundum, zircon, cubic zirconia, morganite, quartz, and can also be used for the substrate if garnet, spinel, cubic zirconia, diamond, meteorite glass, which is in contact with a non-optically homogeneous mineral. It is noted that the space weathering process of solar wind particle injection occurs in space for some minerals (such as merle and pyroxene with total iron content higher than 7%), plagioclase is a mineral which is relatively difficult to weather in space, and plagioclase on the moon is enriched in high-rise plagioclase, which is common and easy to identify, so that the lunar earth can use local materials to preferentially select the plagioclase, and the positive effect that cosmic rays do not change backup data for a long time can be achieved.
The invention provides a polarized jewelry capable of being applied to information storage or identity recognition, which comprises a bracket (1), a light-transmitting layer (11), a first polarizer (21), a nut (3), a gasket (4), a fixed layer (5), a bearing (6), a rock sheet (7), a second polarizer (22), a shaft (8) and a protective sheet (9); wherein, the bracket (1) is made of an alloy at least comprising at least one component of gold, silver, copper, zinc, iron, vanadium, chromium, aluminum, tin, nickel, platinum, palladium, ruthenium, rhodium, iridium, titanium, antimony, manganese, zirconium, hafnium, bismuth, molybdenum, cobalt, rhenium and tungsten, the geometric center of the bracket (1) is fixedly welded or screwed with one end of a shaft (8), a hole is arranged in the middle of a first polaroid (21), the other end of the shaft (8) passes through the hole in the middle of the first polaroid (21) to be fixedly screwed or welded with a fixing nut (3), the fixing layer (5) and a rock slice (7) are fixedly adhered to form a non-detachable sheet at the position where the shaft (8) is clamped by the nut (3) and the bracket (1), the fixing layer (5) is fixedly adhered to a rock slice (7), or fixedly welded, or fixed by grooving, or fixedly bound with a metal wire, or fixedly screwed or fixedly riveted on the outer side of a bearing (6), the outer side of the bearing (6) can rotate, and the inner side is adhered and fixed, or embedded and fixed, or welded and fixed, or grooved and fixed, or a metal wire is bound and fixed with a fixed shaft (8); the protective sheet (9) is made of transparent material and is attached and fixed on the surface of the second polarizer (22).
Preferably, the rock slices (7) are annular in shape, the opaque mineral content of the rock slices is lower than 50%, the optically homogeneous mineral content of the rock slices is lower than 70%, the carbonate-containing mineral content is not more than 20%, and when the mineral content with the birefringence lower than 0.009 exceeds 15%, the thickness of the rock slices is not less than 30 μm; the optical properties are described in "handbook of identifying transparent mineral flakes" of Changhua et al.
Preferably, the support (1) comprises a light-transmitting layer (11), at least 1 LED bulb light source is detachably fixed or embedded and fixed on the inner side of the light-transmitting layer (11), the support (1) is circular, the support (1) is fixedly welded with a hanging ring (13), and the shaft (8) is longer than the bearing (6). Alternatively, the protective sheet (9) attached to the surface of the second polarizer (22) is a convex lens or a Fresnel lens, the surface of the rock sheet (7) which is not contacted with the fixed layer (5) is fixedly attached to the second polarizer (22), and the first polarizer (21) is rotatably fixed on the bearing (6).
Preferably, if the rock slice (7) contains minerals with Mohs hardness of 5.5 or less, the material of the convex lens or Fresnel lens attached to the surface of the second polarizer is at least one of quartz, fused quartz glass, alumina glass, cubic zirconia or film-shaped artificial diamond. Preferably, the rock laminate comprises at least one mineral selected from olivine, diopside, or celadonite. This is because precious stones such as olivine, diopside, etc., or green cord, etc., are known to be common rock-making minerals exhibiting interference colors of class II or higher, which are not only high in hardness, good in durability, and beautiful in interference color, but also are common, and the cost of producing sheets therefrom is low. According to the calculation of materials, equipment loss and labor cost at the end of 2019, the whole process can be completed by only using 25-30 yuan for each slice.
In combination, there is provided an identification method using a rock polarizing sheet substrate storage medium, which is required to be incapable of selecting a single crystal without inclusion and component zones, incapable of selecting a single crystal with an opaque mineral content of more than 50%, incapable of selecting a rock with an optical homogeneous mineral content of more than 70%, incapable of selecting a rock with a clay mineral content of more than 5%, incapable of selecting a rock with a whole rock component solubility of more than or equal to 0.1g, and includes: firstly, selecting a polycrystalline rock material, and grinding to manufacture a rock polarization sheet substrate storage medium; secondly, assembling the polarized jewelry by using components at least comprising a light transmitting layer (11), a first polarizer (21), a fixed layer (5), a bearing (6), a rock sheet (7), a second polarizer (22), a shaft (8) and a protective sheet (9); thirdly, recording pictures or video image data, or optical characteristic data, or mineral particle shape layout characteristic data in the rotation process of the rock polarization sheet substrate storage medium by using a photographic device or an image scanning device, and storing the data; fourthly, editing instruction information of the storage medium of the rock polarization sheet base material rotated to a given angle by a user, wherein the instruction information is mapped and encrypted by first electronic equipment and stored in a cloud or local storage medium, or matching third party passwords or biological characteristics of the storage medium user of the rock polarization sheet base material with the image or video image data or optical characteristic data or mineral particle shape layout characteristic data recorded in the third step of the method, and mapping and encrypting the data by the first electronic equipment and storing the data in the cloud or local storage medium; the fifth step: the holder of the rock polarization sheet base material storage medium collects information in a second electronic device, and judges whether the picture or video image data, or the optical characteristic data, or the mineral particle shape layout characteristic data of the rock polarization sheet base material storage medium is matched with a third party password or biological characteristics of a user; and when the information passes the matching, the second electronic device calls the rock polarization sheet substrate storage medium to rotate to the instruction represented by the appointed angle in the fourth step, and otherwise, does not call the instruction or pops up prompt information which does not pass the verification.
If the original rock slice is not a single crystal and does not develop an oriented structure, even if the same mineral material is used, the colors observed by rotating the original rock slice in the same mineral particle arrangement mode are almost impossible to be completely the same, although the original rock slice is low in manufacturing cost, if the original rock slice can be completely and finely imitated, a large-scale instrument such as a polarizing microscope, an ultrathin slicer, an X-ray fluorescence spectrometer and the like is additionally used, and each mineral particle applied to imitation is rotated by 90 degrees once and once to select the mineral crystal with the same component zone, inclusion layout, interference color and extinction position as the original slice; if the original rock slice comprises 100 mineral crystal grains (the actual observation shows that the selected materials of Hetian jade, jade and Dushan jade scraps are likely to exceed the value), the time for orienting, arranging and cutting one mineral crystal grain is about 7 days, and when the imitation flows are connected in series, the 100 mineral grain slice is estimated to consume at least 700 days of working time and at least 150 times of the cost of the original rock slice for imitation; when the imitation process is performed by connecting a plurality of devices in parallel or simultaneously, although the imitation time is shortened, considering that the required devices are not popular and expensive (laboratories such as universities and research institutes with related devices need to make advance reservation and pay far higher cost than rock slices), the parallel or simultaneous use of a plurality of devices in the imitation process is difficult. Therefore, the jewelry imitation cost provided by the invention is extremely high, and the jewelry imitation cost can be effectively used as a proof for identity recognition.
It is noted that some minerals in rocks have particularly superior durability under specific conditions, have partially artificially synthesized crystals, and also have excellent durability, but the durability is limited, for example, by geological common knowledge, zircon and baddeleyite can be stored at a high temperature of 800 ℃ or more for 25 hundred million years or even 40 hundred million years, but zircon has poor toughness and is easy to crack by impact; diamond, corundum, topaz have higher mohs hardness, but have cleavage, or the chemical property is unstable under the high temperature; pyroxene, green curtain stone, olivine, hornblende, mica interference colors are contrasting colors, but are easily weathered when exposed to hot water. One of these unexpected effects is that some minerals that are unstable on earth have better durability in space or in the extraterrestrial planet than those on earth, so the mineral storage media provided by the present invention can be applied to data backup of extraterrestrial planet.
The invention is simpler to manufacture than the jewelry disclosed in the prior art CN 207909149U. The practice also finds that the polycrystalline gem and jade leftover slice not only can rotate under orthogonal polarization to realize color change, but also has complicated arrangement of mineral particles in the slice, and no two pieces of rock which are completely the same exist in the world, so that the polarized jewelry has irreproducibility, and the polarized jewelry can be used for identity recognition, generates unexpected effects compared with the decoration effect of the jewelry and can realize the functions of identity recognition and data storage without increasing a chip and an antenna of a comparison file which are arranged on the jewelry body.
As can be seen from the above description and practice of the present invention, the technical solution provided by the present invention has the following advantages compared with the prior art: 1, the leftover materials are low in cost for manufacturing the rock polarizing sheet; 2, the jade leftover materials or the mineral rock slice samples and the polaroids are used for manufacturing the rotationally discolored jewelry or storage media, so that precious gemstones and mineral materials are saved; 3, the rock slice is almost not reproducible, and can be used as a new effect of a low-cost identity identification voucher as jewelry; 4: the polarized light jewelry can be used for identity recognition without additionally implanting electronic equipment on the jewelry, and generates unexpected identity recognition effect on the basis of the decoration effect of the jewelry; 5, the invention can be more resistant to high temperature, corrosion and radiation than the conventional storage medium when used as the storage medium of a black box or a space detector.

The first embodiment is as follows: rock polarizing sheet substrate storage media, methods of manufacture and uses thereof:
the rock polarizing sheet base material comprises crystalline rock or mineral sheets with the thickness of 5-1000 mu m and polarizing sheets detachably fixed on two sides of the sheets; the crystalline rock cannot be rock with opaque mineral content higher than 35%, cannot have optical homogeneous mineral content higher than 80%, cannot have clay mineral content higher than 5%, cannot be rock with whole rock component solubility greater than or equal to 0.1g, and cannot be rock with mineral content of Mohs hardness less than or equal to 5 and greater than 50%; the reason why the thickness range is large is that when the same order interference color is presented, the thickness (d) of the mineral sheet is inversely related to the birefringence (DR) of the mineral, and the optical path difference R' = d × DR, which is why the color of the carbonate mineral (DR ≈ 0.2) with the thickness of 10 μm under orthogonal polarization is changed into the apatite (DR ≈ 0.002) which can present the same interference color only when the thickness is 1000 μm; when R' is less than or equal to 350nm and less than or equal to 2000nm, the crystalline flakes can be observed to rotate under orthogonal polarization to show a changing seven-color. Because of the foregoing practical findings, when mineral materials including, but not limited to, olivine, pyroxene, plagioclase, artificial cubic zirconia, and synthetic mosanguinite are exposed to a high temperature of 1600 ℃ of 1000-; as is known in the prior art, the temperature range of 1000-1600 ℃ is possibly the temperature experienced by a space detector and a black box of a crash aircraft, so the rock polarization sheet substrate storage medium is suitable for data backup of the space detector and the black box of the aircraft.
In a matching way, the invention provides a manufacturing method of the rock polarization sheet substrate storage medium, which comprises the following steps: selecting rock slice raw materials, wherein the rock slice raw materials cannot contain opaque mineral content higher than 60%, optical homogeneous mineral content higher than 70%, clay mineral content higher than 5%, and rock with whole rock component solubility higher than or equal to 0.1 g; step two: cutting transparent mineral or rock into blank blocks with the length of more than 5mm, the width of more than 2mm and the thickness of no more than 2mm by using a slicing machine or a line cutting machine; step three: grinding and polishing one surface of the blank block by using carborundum or chromium oxide or corundum or pomegranate sand or diamond powder to obtain a first plane, wherein the fluctuation of the contact surface of the first plane is not more than 2 mu m; step four: bonding the first plane with Canadian Gum, or polymethylmethacrylate, or isocyano-acrylate, or frit glass, or polylactic acid, or epoxy resin to a carrier sheet which is one of cubic zirconia, or synthetic diamond, or tempered glass, or fused quartz glass, or fused corundum glass, or an alloy containing at least one of titanium, niobium, zirconium, hafnium, tungsten, molybdenum, chromium, platinum, iridium, gold; when the carrier sheet is transparent, a polaroid does not need to be clamped between the first plane and the carrier sheet, otherwise, the polaroid needs to be clamped between the first plane and the carrier sheet, and the fluctuation of the contact surface of the carrier sheet and the first plane is not more than 2 mu m in order to avoid scattering; step five: after Canadian gum, or polymethyl methacrylate, or isocyano methyl acrylate, or sintered glass, or polylactic acid, or epoxy resin is dried and then is firmly bonded with a carrier sheet in a curing way, at least three diamond sheets with the same thickness are surrounded on the other side of the blank block at equal intervals and angles, the other side of the blank block is ground until the thickness of the blank block meets R '= d × DR and the thickness of R' is more than or equal to 350nm and less than or equal to 2000nm, a second plane is obtained, and the fluctuation of the second plane is not more than 1 [ mu ] m; step six: and the second plane is bonded with the protection sheet, the protection sheet is one of cubic zirconia, synthetic diamond, toughened glass, fused quartz glass or fused corundum glass, in order to avoid scattering, two surfaces of the protection sheet are polished into planes with the fluctuation of not more than 1 mu m, the fluctuation of the contact surface of the second plane and the protection sheet is not more than 1 mu m, and the protection sheet is required to be transparent. Thus, the rock polarizing sheet substrate storage medium is composed of the carrier sheet, the rock mineral sheet and the protective sheet. Due to the progress of advanced micro-area detection technologies such as an electron probe, a laser plasma mass spectrometer and the like, a plurality of scholars are better than rock and ore slices without protective plates for research and identification of a polarizing microscope at present, and obviously, the manufacturing of the slices omits the step six; and if and only if the rock polarization sheet mineral at least contains 75% of minerals with Mohs hardness more than or equal to 6 and melting point more than or equal to 1200 ℃, the manufacturing of the rock polarization sheet base material storage medium can omit the sixth step, and the constraint ensures that the rock polarization sheet base material is not easy to wear.
Example two: the rock polarizing sheet substrate is applied to the black box of the airplane:
the black box (201) at least comprises a rock polarization sheet substrate storage medium (70) and a laser system, wherein the laser system comprises a controller (208), a laser source (202), a laser writer (203), a laser positioner (206), a laser reader (205) and an optical fiber (207); the laser writer (203), the laser positioner (206) and the laser reader (205) are wrapped in the black box, the laser source is connected with the laser writer (203), the laser positioner (206) and the laser reader (205) through the optical fiber (207) to realize optical path connection and electrical connection, and the rock polarization sheet base material is storedThe storage medium (70) is movably fixed on a sliding rail (209), the sliding rail (209) is fixedly wrapped in the black box, and a vacuum chamber or a transparent interlayer (204) surrounds the rock polarization sheet base material; the laser system works at a pulse frequency of 10-50 Hz, the frequency of the laser system is constant in the single route writing process, the laser writer (203) etches the rock polarization sheet substrate storage medium (70) with a laser beam spot, and the range of the beam spot energy is 0.2-6 J.cm– 2(ii) a The preselected area of the rock polarization sheet substrate storage medium (70) is selected by a laser locator and a laser reader through extinction positions and interference colors, and can also be determined by a known EBSD technology, wherein the EBSD technology is a method for selecting and analyzing mineral particle components and structure structures through electron back scattering diffraction, and the article published by the public number of the Chinese auxiliary enterprise is described in detail; the extinction bit and the interference color information can be manually set by a controller (208), or can be electrically stored, or can be magnetically stored, or can be optically stored to control a laser source (202), a laser writer (203), a laser positioner (206) and a laser reader (205); when a preselected area of the rock polarization sheet substrate storage medium (70) is ablated, the diameter of a laser beam spot of an ablation analysis point is not more than 50 mu m. The laser system is uninterrupted in flight, and pit combinations representing recorded and imaged information can be etched on mineral particles in real time or on the surface of the rock polarizing sheet substrate storage medium (70) according to the vibration track of cabin sound waves. In combination with the actual properties of minerals, the material of the rock polarization sheet substrate storage medium (70) comprises at least 2 of olivine, pyroxene, celadon, corundum, zircon, cubic zirconia, morusite, grapestite, natrolite, diaspore, tourmaline and quartz, because multiple etching is carried out, multiple mineral particles of one sheet or a carrier sheet attached to the rock polarization sheet substrate storage medium (70) are simultaneously subjected to laser etching to backup multiple identical data, even if one substrate is damaged, each mineral is difficult to completely damage, and multiple backups are safer and more reliable; the characterization of the substrate as damaged also helps to determine the specific type of catastrophic event experienced by the media. For example, olivine and pyroxene cannot endure the sea for more than 5 yearsWhen water corrosion occurs, the grape stone, the natrolite and the diaspore cannot resist the high temperature of more than 200 ℃, the electrical property of the tourmaline and the quartz is changed at the high temperature, and cracks are increased, so when the events occur, the change of the minerals on the storage medium (70) of the rock polarization sheet base material is helpful for judging the events experienced by the black box. When the accident occurs, the operation of the laser beam is reversed by recovering the rock polarizing sheet substrate storage medium (70) and etching traces by the laser beam spot thereon, and the pre-accident recording is resumed. Techniques for inverting the sound by the operation of a laser beam are well known and have been used in the fields of laser-to-sound signal conversion and laser eavesdropping.
Example three: the rock polarizing sheet base material is applied to the purpose of moon surface data backup:
lunar vehicle test data was backed up in a manner that the laser beam spot etched rock polarizer substrates. On the surface of the moon, the rock polarization sheet substrate storage medium is manufactured according to the method described in the first embodiment, can be carried by earth missions, and can also be prepared by polishing lunar soil powder from selected palygorskite in the local sources of the moon, and can be detachably fixed on a space detector. When the preselected area of the rock polarization sheet substrate storage medium is ablated, in order to enable the data storage capacity of a unit area to be large enough, the diameter of a laser beam spot in the laser ablation process is not more than 50 mu m, and the range of the energy of the laser beam spot is not more than 6 J.cm- 2. In the data transmission and analysis process, the laser system is continuously and electrically connected with the test system, the laser system receives the strength of the electric signal of the test system in real time, the electric signal of the test data is converted into the laser signal, the laser signal is etched on the lunar rock mineral according to the agreed format, the agreed format is determined by programming in advance, for example, different beam spot diameters represent different data types, the etching depth represents the numerical value, and pit combinations representing spectrum, image, component content and temperature information can be etched on the mineral particles in real time. In combination with the actual nature of the mineral, when the space probe is on the lunar surface, suitable rock-polarizing sheet substrates include at least 2 of plagioclase, olivine, aeolianite, enstatite, garnet, celadon, tetrahedron, corundum, zircon, cubic zirconia, mordenite, quartz, if garnet is present in the rock, and,Spinel, cubic zirconia, diamond, meteorite glass and non-optical homogeneous mineral contact can also be selected for the rock polaroid substrate storage medium raw material, otherwise, the selection is not performed. It is noted that the space weathering process of solar wind particle injection occurs in space for some minerals (such as merle and pyroxene with total iron content higher than 7%), plagioclase is a mineral which is relatively difficult to weather in space, plagioclase is enriched in alpine plagioclase on the moon, the rock is common and easy to identify, and laser etching information of plagioclase can be stored for at least 50 years under radiation conditions, so that the moon takes local materials and preferentially selects the plagioclase, and the positive effect that cosmic rays do not change backup data for a long time can be achieved.
