S102: For each polarization state of the designated optical signal, obtain the linearly polarized light signal in the polarization state from the designated optical signal through the polarizer corresponding to the polarization state, and polarize the linearly polarized light signal. An optical signal is incident on the designated metasurface.

Furthermore, when the business platform receives a specified optical signal, for each polarization state of the specified optical signal, the linearly polarized light in that polarization state can be filtered from the specified optical signal through the polarizer corresponding to the polarization state. signal, and the linearly polarized light signal is incident on the specified metasurface.

S103: Obtain the outgoing light signal corresponding to the linearly polarized light signal based on the incident linearly polarized light signal through the designated metasurface.

Further, the server can obtain the outgoing light signal corresponding to the linearly polarized light signal based on the incident linearly polarized light signal by specifying the metasurface.

Wherein, the above designated metasurface can be determined in advance based on the intensity distribution of each designated image data, the corresponding relationship between each designated image data and each polarization state, and the complex amplitude required to construct the designated metasurface is determined based on The required complex amplitude determines the micro-nano structural parameters required to compose the specified metasurface.

In addition, in actual application scenarios, since the complex amplitude is determined based on the intensity distribution of each specified image data, there is often partial crosstalk information in the determined complex amplitude, resulting in a metasurface constructed based on the above complex amplitude. The specified image data generated at the receiving end under the irradiation of the linearly polarized light signal contains part of the information of other specified image data, as shown in Figure 3A.

It can be seen from Figure 3A that after introducing additional complex amplitudes through the above method to shield the crosstalk information contained in the initial complex amplitudes, it can effectively improve the linearly polarized light signal corresponding to the specified image data for each specified image data and Specifies the sharpness of the specified image data acquired by the specified metasurface.

S104: Obtain designated image data corresponding to the linearly polarized light signal in a designated area of the receiving module through the emitted light signal, and perform task execution based on the received designated image data.

Further, the server can obtain designated image data corresponding to the linearly polarized light signal in a designated area of the receiving module by emitting the light signal, and perform task execution based on the received designated image data.

Specifically, the server can detect the polarization state of the outgoing light signal through an analyzer to obtain the detected outgoing light signal. By detecting the outgoing light signal, the server can obtain designated image data corresponding to the linearly polarized light signal in a designated area at the receiving end.

For example: when you need to obtain a linearly polarized light signal with a polarization state of 45°, you can filter the received specified optical signal through a polarizer with a polarization state of 45° to obtain linearly polarized light with a polarization state of 45°. signal, and then the obtained linearly polarized light signal with a polarization state of 45° can be incident on the specified metasurface, so as to pass through the specified metasurface to obtain the outgoing light signal, and pass through the analyzer whose polarization state is consistent with the polarizer (i.e., A polarizer with a polarization state of 45°) detects the polarization state of the emitted light signal, and obtains the detected emitted light signal.

It should be noted that when the designated metasurface receives different incident light signals, the generated outgoing light signals will all present designated image data in the same area (ie, designated area) of the receiving end.

Improvements in a technology can be clearly distinguished as hardware improvements (for example, improvements in circuit structures such as diodes, transistors, switches, etc.) or software improvements (improvements in method processes). However, with the development of technology, many improvements in today's method processes can be regarded as direct improvements in hardware circuit structures. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that an improvement of a method flow cannot be implemented using hardware entity modules.

Designers can program themselves to "integrate" a digital system on a PLD, instead of asking chip manufacturers to design and produce dedicated integrated circuit chips. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly implemented using "logic compiler" software, which is similar to the software compiler used in program development and writing. Before compiling, The original code must also be written in a specific programming language, which is called Hardware Description Language (HDL). There is not only one type of HDL, but many types, such as ABEL (AdvancedBoolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (JavaHardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby HardwareDescription Language), etc. The most commonly used one at present is VHDL ( Very-High-Speed IntegratedCircuit Hardware Description Language) and Verilog.
