Description

Technical Field

[0001] The present application relates to the field of optoelectronic technology, and in particular to a photoelectric conversion regulation method, a regulation system, and a photoelectric conversion system. Background Art

[0002] Laser Wireless Power Transmission (LWPT) technology is a key development in wireless energy transmission. Its system consists of a laser transmitter, a transmission medium, and a laser receiver. LWPT utilizes lasers as energy carriers to wirelessly transmit energy from a source to a receiver. Its fundamental principle is photoelectric conversion. At the transmitter, a high-power laser converts electrical energy into a high-energy-density laser beam, which is then transmitted through the atmosphere or other media. At the receiver, a photoelectric conversion device (such as a photovoltaic cell) converts the received laser energy back into electrical energy, thus enabling wireless energy transmission.

[0003] However, due to factors such as laser beam divergence, atmospheric turbulence, atmospheric transmission loss, and precise beam pointing control, the current laser energy transmission system still suffers from low energy transmission efficiency and short transmission distance. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a photoelectric conversion regulation method, a regulation system, and a photoelectric conversion system to solve the above-mentioned problems.

[0005] In a first aspect, the present application provides a method for adjusting photoelectric conversion, the method comprising: performing phase adjustment on a first polarized light and a second polarized light respectively according to a first preset phase adjustment parameter to obtain a first synthetic light beam; wherein the first synthetic light beam is generated based on the first polarized light and the second polarized light after phase adjustment, and the first polarized light and the second polarized light are obtained based on polarization splitting of a target light beam, and the propagation directions of the first polarized light and the second polarized light are perpendicular; collecting a first electric energy signal generated by a photoelectric conversion device; wherein the first electric energy signal is generated based on photoelectric conversion of the first synthetic light beam; according to a second preset phase adjustment parameter, controlling the phase adjustment of the first polarized light and the second polarized light respectively to obtain a second synthetic light beam; wherein the adjustment polarity of the first preset phase adjustment parameter is opposite to that of the second preset phase adjustment parameter; collecting a second electric energy signal generated by the photoelectric conversion device; wherein the second electric energy signal is generated based on photoelectric conversion of the second synthetic light beam; adjusting the phase adjustment parameter according to the first electric energy signal and the second electric energy signal until the electric energy signal generated by the photoelectric conversion device meets the target electric energy condition.

[0006] The photoelectric conversion adjustment method designed in this scheme uses polarization splitting to split the target light beam into two polarized lights with mutually perpendicular propagation directions, and phase-adjusts the first polarized light and the second polarized light respectively, and then synthesizes and transmits them to the photoelectric conversion device. The phase adjustment parameters are adjusted by collecting the electric energy signal generated by the photoelectric conversion device based on the synthetic light field until the electric energy signal generated by the photoelectric conversion device meets the target electric energy conditions. Therefore, the photoelectric conversion adjustment method designed in this scheme, on the one hand, uses the synthetic light field generated by polarization splitting and phase adjustment to correct the polarization on the basis of achieving phase correction, thereby compensating for the influence of turbulence, and based on the polarization correction, it also increases the laser transmission efficiency in foggy conditions; at the same time, the electric energy signal generated by the photoelectric conversion device based on the synthetic light field is used as a feedback indicator for phase adjustment, so that the electric energy signal of the photoelectric conversion device can reflect the degree of matching between the phase of the light beam and the photoelectric conversion device, and then the electric energy signal generated by the photoelectric conversion device can be achieved to the optimal state through phase adjustment, thereby improving the absorption efficiency of the photoelectric conversion device for laser.

[0007] In an optional implementation of the first aspect, the phase adjustment parameter is adjusted according to the first electric energy signal and the second electric energy signal until the electric energy signal generated by the photoelectric conversion device meets the target electric energy condition, including: determining the target polarity adjustment direction of the phase adjustment parameter according to the first electric energy signal and the second electric energy signal; adjusting the phase adjustment parameter according to the target polarity adjustment direction until the electric energy signal generated by the photoelectric conversion device meets the target electric energy condition.

[0008] In an optional implementation of the first aspect, the target polarity adjustment direction of the phase adjustment parameter is determined based on the first electric energy signal and the second electric energy signal, including: calculating a first electric energy difference between the electric energy value corresponding to the first electric energy signal and the target electric energy value; calculating a second electric energy difference between the electric energy value corresponding to the second electric energy signal and the target electric energy value; and determining the polarity adjustment direction of the phase adjustment parameter corresponding to the electric energy signal having a smaller difference between the first electric energy difference and the second electric energy difference as the target polarity adjustment direction of the phase adjustment parameter.

[0009] In the above implementation mode, this scheme determines the polarity adjustment direction of the phase adjustment parameter corresponding to the electric energy signal with the smaller difference between the first electric energy difference and the second electric energy difference as the target polarity adjustment direction of the phase adjustment parameter, thereby quickly determining the target polarity adjustment direction and avoiding the problem of low processing efficiency caused by the error in the large direction of polarity adjustment.

[0010] In an optional implementation of the first aspect, the phase adjustment parameter is adjusted according to the target polarity adjustment direction until the electric energy signal generated by the photoelectric conversion device meets the target electric energy condition, including: obtaining a gradient value of the parameter adjustment; adjusting the initial phase adjustment parameter according to the target polarity adjustment direction based on the gradient value to obtain a first updated phase adjustment parameter; wherein the initial phase adjustment parameter is the phase adjustment parameter corresponding to the electric energy signal having the smaller difference between the first electric energy difference and the second electric energy difference; according to the first updated phase adjustment parameter, the first polarized light and the second polarized light are phase adjusted respectively to obtain a first updated synthetic light beam; collecting the first updated electric energy signal generated by the photoelectric conversion device; wherein the first updated electric energy signal is generated based on photoelectric conversion of the first updated synthetic light beam; judging whether the difference between the electric energy value corresponding to the first updated electric energy signal and the target electric energy value is less than a preset threshold; if it is determined that the difference between the electric energy value corresponding to the first updated electric energy signal and the target electric energy value is less than the preset threshold, then determining that the electric energy signal generated by the photoelectric conversion device meets the target electric energy condition.

[0011] In an optional implementation manner of the first aspect, obtaining the gradient value of the parameter adjustment includes: calculating the electric energy difference between the first electric energy signal and the second electric energy signal to obtain the gradient value of the parameter adjustment.

[0012] In an optional implementation manner of the first aspect, the phase adjustment parameter is adjusted according to the target polarity adjustment direction until the electric energy signal generated by the photoelectric conversion device meets the target electric energy condition, and also includes: if it is determined that the difference between the electric energy value corresponding to the first updated electric energy signal and the target electric energy value is not less than a preset threshold, then according to the first updated electric energy signal and the electric energy difference of the electric energy signal with the smaller difference between the first electric energy difference and the second electric energy difference, an updated gradient value is obtained; according to the updated gradient value, the first updated phase adjustment parameter is adjusted according to the target polarity adjustment direction to obtain a second updated phase adjustment parameter; according to the second updated phase adjustment parameter, the first polarized light and the second polarized light are phase-adjusted respectively to obtain a second updated synthetic light beam; the second updated electric energy signal generated by the photoelectric conversion device is collected; wherein the second updated electric energy signal is generated based on photoelectric conversion of the second updated synthetic light beam; it is determined whether the difference between the electric energy value corresponding to the second updated electric energy signal and the target electric energy value is less than the preset threshold; if it is determined that the difference between the electric energy value corresponding to the second updated electric energy signal and the target electric energy value is less than the preset threshold, it is determined that the electric energy signal generated by the photoelectric conversion device meets the target electric energy condition.

[0013] In the above implementation mode, the gradient value designed in this scheme is continuously and dynamically updated through the difference between the last electric energy signal and the previous electric energy signal. In this way, the phase adjustment parameter is continuously smoothly transitioned from "coarse adjustment" to "fine adjustment" through the historical difference, thereby improving the adjustment accuracy of the phase adjustment parameter while ensuring the adjustment efficiency.

[0014] In an optional implementation of the first aspect, obtaining the gradient value of the parameter adjustment includes: obtaining a preset fixed gradient value of the parameter adjustment.

[0015] In the above implementation, the fixed gradient value does not require real-time calculation or dynamic adjustment of the adjustment step size, which can greatly simplify the algorithm calculation process, thereby improving the adjustment efficiency of the phase adjustment parameters. In addition, the fixed gradient value unifies the "basic unit" of each adjustment, facilitating system calibration and result reproduction.

[0016] In a second aspect, the present application provides a photoelectric conversion regulation system, which includes a first polarization beam splitter, a first light field modulator, a second light field modulator, a second polarization beam splitter and a control device; the first polarization beam splitter is used to perform polarization beam splitting on a received target light beam to obtain a first polarized light and a second polarized light; wherein the propagation direction of the first polarized light is perpendicular to that of the second polarized light; the first light field modulator is used to perform phase adjustment on the first polarized light according to a first preset phase adjustment parameter to obtain a first phase-adjusted light, and to perform phase adjustment on the first polarized light according to a second preset phase adjustment parameter to obtain a third phase-adjusted light; the second light field modulator is used to perform phase adjustment on the second polarized light according to the first preset phase adjustment parameter to obtain a second phase-adjusted light, and The second polarized light is phase-adjusted according to a second preset phase adjustment parameter to obtain a fourth phase-adjusted light; the second polarization beam splitting device is used to combine the first phase-adjusted light and the second phase-adjusted light into a first synthetic light beam and transmit it to the photoelectric conversion device, and to combine the third phase-adjusted light and the fourth phase-adjusted light into a second synthetic light beam and transmit it to the photoelectric conversion device; the control device is used to collect the first electric energy signal and the second electric energy signal generated by the photoelectric conversion device; wherein the first electric energy signal is generated based on the photoelectric conversion of the first synthetic light beam, and the second electric energy signal is generated based on the photoelectric conversion of the second synthetic light beam; the control device is also used to adjust the phase adjustment parameters according to the first electric energy signal and the second electric energy signal until the electric energy signal generated by the photoelectric conversion device meets the target electric energy condition.

[0017] The photoelectric conversion adjustment system designed above first splits the target light beam into two polarized light beams with mutually perpendicular propagation directions through a first polarization beam splitter. The first and second light field modulators respectively perform phase adjustment on the first and second polarized light beams. The phase-adjusted light beams are synthesized and transmitted to the photoelectric conversion device through a second polarization fractionator. The control device adjusts the phase adjustment parameters by collecting the electric energy signal generated by the photoelectric conversion device based on the synthesized light field until the electric energy signal generated by the photoelectric conversion device meets the target electric energy condition. Therefore, the photoelectric conversion adjustment system designed in this scheme not only corrects the phase by generating the synthesized light field through polarization beam splitting and phase adjustment, but also corrects the polarization, thereby compensating for the influence of turbulence. The polarization correction also increases the laser transmission efficiency in foggy conditions. At the same time, the electric energy signal generated by the photoelectric conversion device based on the synthesized light field is used as a feedback indicator for phase adjustment. In this way, the electric energy signal of the photoelectric conversion device can reflect the degree of phase matching between the light beam and the photoelectric conversion device. Then, through phase adjustment, the electric energy signal generated by the photoelectric conversion device can be optimized, thereby improving the absorption and conversion efficiency of the photoelectric conversion device for laser light.

[0018] In an optional embodiment of the second aspect, the first light field modulator includes a first deformable mirror, and the second light field modulator includes a second deformable mirror.

[0019] In the above embodiment, the driving unit of the deformable mirror (such as piezoelectric driving) has an extremely fast response speed and high real-time performance, thereby improving the response rate of the photoelectric conversion regulation system.

[0020] In a third aspect, the present application provides a photoelectric conversion system, which includes a light beam emitting device, a photoelectric conversion device, and a photoelectric conversion regulation system as described in any one of the second aspects, wherein the light beam emitting device and the photoelectric conversion device are electrically connected to a control device in the photoelectric conversion regulation system; the light beam emitting device is used to emit a target light beam to a first polarization beam splitting device; and the photoelectric conversion device is used to convert the received synthetic light beam into a corresponding electrical energy signal.

[0021] The photoelectric conversion system designed above includes the photoelectric conversion regulation system described above. Therefore, the designed photoelectric conversion system, on the one hand, corrects the polarization on the basis of phase correction by using the synthetic light field generated by polarization splitting and phase adjustment, thereby compensating for the influence of turbulence, and the laser transmission efficiency in foggy conditions is also increased based on polarization correction; at the same time, the electric energy signal generated by the photoelectric conversion device based on the synthetic light field is used as a feedback indicator of phase adjustment, so that the electric energy signal of the photoelectric conversion device can reflect the degree of matching between the phase of the light beam and the photoelectric conversion device, and then the electric energy signal generated by the photoelectric conversion device can be achieved in the optimal state through phase adjustment, thereby improving the absorption and conversion efficiency of the photoelectric conversion system for laser.

[0037] Laser Wireless Power Transmission (LWPT) technology is a key development in wireless energy transmission. Its system consists of a laser transmitter, a transmission medium, and a laser receiver. LWPT utilizes lasers as energy carriers to wirelessly transmit energy from a source to a receiver. Its fundamental principle is photoelectric conversion. At the transmitter, a high-power laser converts electrical energy into a high-energy-density laser beam, which is then transmitted through the atmosphere or other media. At the receiver, a photoelectric conversion device (such as a photovoltaic cell) converts the received laser energy back into electrical energy, thus enabling wireless energy transmission.

[0038] However, due to factors such as laser beam divergence, atmospheric turbulence, atmospheric transmission loss, and precise beam pointing control, the current laser energy transmission system still suffers from low energy transmission efficiency and short transmission distance.

[0039] Based on the above problems, the present application designs a photoelectric conversion adjustment method, an adjustment system, and a photoelectric conversion system. This scheme first uses polarization splitting to split the target light beam into two polarized lights with mutually perpendicular propagation directions, and phase-adjusts the first polarized light and the second polarized light respectively, and then synthesizes and transmits them to the photoelectric conversion device. The phase adjustment parameter is adjusted by collecting the electric energy signal generated by the photoelectric conversion device based on the synthetic light field until the electric energy signal generated by the photoelectric conversion device meets the target electric energy condition. Therefore, the photoelectric conversion adjustment method designed in this scheme, on the one hand, uses the synthetic light field generated by polarization splitting and phase adjustment to correct the polarization on the basis of achieving phase correction, thereby compensating for the influence of turbulence, and based on polarization correction, it also increases the laser transmission efficiency in foggy conditions; at the same time, the electric energy signal generated by the photoelectric conversion device based on the synthetic light field is used as a feedback indicator for phase adjustment, so that the electric energy signal of the photoelectric conversion device can reflect the degree of matching between the light beam and the photoelectric conversion device, and then the electric energy signal generated by the photoelectric conversion device can be achieved to the optimal state through phase adjustment, thereby improving the absorption efficiency of the photoelectric conversion device for laser.

[0040] Based on the above ideas, this application first provides a photoelectric conversion adjustment method, which is applied to computing devices, including but not limited to computers, servers, control devices, control chips, etc., which can be selected according to actual application scenarios, such as Figure 1 As shown, the photoelectric conversion adjustment method can be implemented by the following methods, including: Step S100: performing phase adjustment on the first polarized light and the second polarized light respectively according to a first preset phase adjustment parameter to obtain a first composite light beam.

[0041] Step S110: collecting a first electric energy signal generated by the photoelectric conversion device.

[0042] Step S120: According to the second preset phase adjustment parameter, the phases of the first polarized light and the second polarized light are controlled to be adjusted respectively to obtain a second composite light beam.

[0043] Step S130: collecting a second electric energy signal generated by the photoelectric conversion device.

[0044] Step S140: adjusting the phase adjustment parameter according to the first power signal and the second power signal until the power signal generated by the photoelectric conversion device meets the target power condition.

[0045] In the above embodiment, the first synthetic light beam is generated based on the first polarized light and the second polarized light after phase adjustment. Specifically, this scheme can use a first preset phase adjustment parameter to phase adjust the first polarized light and the second polarized light respectively, and then polarization combine the first polarized light after phase adjustment and the second polarized light after phase adjustment to obtain the first synthetic light beam.

[0046] The first polarized light and the second polarized light are obtained by polarization splitting a target light beam, with the propagation directions of the first polarized light and the second polarized light being perpendicular. As a specific example, the first polarized light and the second polarized light obtained by polarization splitting may be s-polarized light and p-polarized light obtained by polarization splitting, with propagation directions perpendicular to each other. The phase adjustment parameter may be an adjustment parameter of an optical element that performs phase adjustment on the first polarized light and the second polarized light. For example, as a possible example, this solution may use a first preset phase adjustment parameter to phase adjust the first polarized light through a first optical modulator, and use a second preset phase adjustment parameter to phase adjust the second polarized light through the optical modulator. In this case, the phase adjustment parameter designed in this solution may implement a drive signal or control input for the first and second optical modulators. Specifically, as a specific example, assuming that the first and second optical modulators are both deformable mirrors, since deformable mirrors convert electrical signals into mechanical deformations to ultimately achieve optical phase modulation, the phase adjustment parameter set in this solution may be the drive electrical signal for the deformable mirrors.

[0047] When the first combined light beam is obtained in the above manner, the first combined light beam can be transmitted to the photoelectric conversion device, so that the photoelectric conversion device performs photoelectric conversion based on the first combined light beam to generate a first electrical energy signal. This solution collects and temporarily stores the first electrical energy signal generated by the photoelectric conversion device.

[0048] This solution continues to control the phase adjustment of the first polarized light and the second polarized light respectively according to the second preset phase adjustment parameter to obtain a second synthetic light beam, wherein the first polarized light and the second polarized light are obtained by polarization splitting of the target light beam described above.

[0049] The method for generating the second composite light beam is similar to the method for generating the first composite light beam described above and will not be repeated here. The difference is that the phase adjustment of the first polarized light and the second polarized light is performed based on a second preset phase adjustment parameter, and the adjustment polarity of the second preset phase adjustment parameter is opposite to that of the first preset phase adjustment parameter. The adjustment polarity indicates the direction of the signal phase change (advance or lag) changed by phase adjustment to achieve a specific signal processing goal. Specifically, as a possible example, the first preset phase adjustment parameter set in this solution is an advance adjustment, which is a positive value, and the second preset phase adjustment parameter set in this solution is a lag adjustment, which is a negative value.

[0050] After the phase adjustment of the second preset phase adjustment parameter is achieved in the above manner, this solution also performs polarization combination of the first polarized light and the second polarized light whose phase adjustment of the second preset phase adjustment parameter is completed to obtain a second synthetic light beam. The second synthetic light beam can be transmitted to the photoelectric conversion device, so that the photoelectric conversion device performs photoelectric conversion based on the second synthetic light beam to generate a second electrical energy signal. This solution collects the second electrical energy signal generated by the photoelectric conversion device.

[0051] Based on the above process, this solution can collect and obtain the first electric energy signal and the second electric energy signal. This solution can adjust the phase adjustment parameters according to the first electric energy signal and the second electric energy signal until the electric energy signal generated by the photoelectric conversion device meets the target electric energy conditions.

[0052] Specifically, as a possible implementation method, this solution can adjust the phase adjustment parameters in the following way: Figure 2 Shown, including: Step S200: determining a target polarity adjustment direction of a phase adjustment parameter according to the first power signal and the second power signal.

[0053] Step S210: adjusting the phase adjustment parameter according to the target polarity adjustment direction until the power signal generated by the photoelectric conversion device meets the target power condition.

[0054] In the above embodiment, it is described above that the phase adjustment polarity of the first preset phase adjustment parameter and the second preset phase adjustment parameter are different, which makes the phase of the composite light beam transmitted to the photoelectric conversion device after phase adjustment different, thereby making the electric energy signal generated by the photoelectric conversion device based on the composite light beam different. In this regard, the present solution can determine the target polarity adjustment direction of the phase adjustment parameter based on the first electric energy signal and the second electric energy signal. Specifically, as a possible embodiment, the electric energy signal can be the electric energy value generated by the photoelectric conversion device, wherein the electric energy value can be a voltage value, a current value, or an electric power value, etc. In the photoelectric conversion process, the more electric energy converted by the light beam, the better. Based on this, the present solution can compare the first electric energy signal with the second electric energy signal, and use the phase adjustment parameter corresponding to the electric energy signal with the larger electric energy value between the first electric energy signal and the second electric energy signal as the target polarity adjustment direction. For example, the first preset phase adjustment parameter described above is lead adjustment, which is a positive value. The second preset phase adjustment parameter set in this scheme is lag adjustment, which is a negative value. The electric energy value of the first electric energy signal generated by the photoelectric conversion device based on the first synthetic light beam is greater than the electric energy value of the second electric energy signal generated by the second synthetic light beam. Then, this scheme determines the lead adjustment direction (the direction in which the phase adjustment parameter is a positive value) as the target polarity adjustment direction.

[0055] As another possible implementation, this solution may also compare the first and second electrical energy signals with the target electrical energy values ​​of the photoelectric conversion device, and use the phase adjustment parameter corresponding to the electrical energy signal closest to the target electrical energy value between the first and second electrical energy signals as the target polarity adjustment direction. The target electrical energy value may represent the electrical energy value required to be generated by the photoelectric conversion device through photoelectric conversion, and the target electrical energy value may be less than or equal to the maximum conversion electrical energy value of the photoelectric conversion device, which represents the maximum electrical energy value that the photoelectric conversion device can generate based on the light beam.

[0056] Specifically, as a specific implementation method, this scheme can calculate the first electric energy difference between the electric energy value corresponding to the first electric energy signal and the target electric energy value; calculate the second electric energy difference between the electric energy value corresponding to the second electric energy signal and the target electric energy value; and determine the polarity adjustment direction of the phase adjustment parameter corresponding to the electric energy signal with the smaller difference between the first electric energy difference and the second electric energy difference as the target polarity adjustment direction of the phase adjustment parameter.

[0057] After determining the target polarity adjustment direction of the phase adjustment parameter in the above manner, this solution can adjust the phase adjustment parameter according to the target polarity adjustment direction until the power signal generated by the photoelectric conversion device meets the target power condition.

[0058] As a possible implementation manner, the gradient value of the parameter adjustment set in this solution can be preset, and the gradient value of each parameter adjustment is a fixed value.

[0059] In the aforementioned fixed gradient value scenario, this solution can first obtain a fixed gradient value for parameter adjustment, then adjust the initial phase adjustment parameter based on the fixed gradient value and the target polarity adjustment direction to obtain a first updated phase adjustment parameter. The initial phase adjustment parameter is the phase adjustment parameter corresponding to the smaller difference between the first and second electric energy differences. For example, according to the above example, if the leading adjustment direction (the direction in which the phase adjustment parameter is a positive value) is determined as the target polarity adjustment direction, then the initial phase adjustment parameter is the first preset phase adjustment parameter.

[0060] Based on the first updated phase adjustment parameter obtained above, this solution continues to phase-adjust the first polarized light and the second polarized light according to the first updated phase adjustment parameter to obtain a first updated composite light beam. The process of obtaining the first updated composite light beam is similar to the process of obtaining the first composite light beam described above and will not be repeated here.

[0061] Then, this scheme collects the first updated electric energy signal generated by the photoelectric conversion device based on the photoelectric conversion of the first updated synthetic light beam, and determines whether the difference between the electric energy value corresponding to the first updated electric energy signal and the target electric energy value is less than the preset threshold; if it is determined that the difference between the electric energy value corresponding to the first updated electric energy signal and the target electric energy value is less than the preset threshold, it is determined that the electric energy signal generated by the photoelectric conversion device meets the target electric energy condition.

[0062] If it is determined that the difference between the electric energy value corresponding to the first updated electric energy signal and the target electric energy value is not less than the preset threshold value, this scheme will adjust the first updated phase adjustment parameter again according to the target polarity adjustment direction based on the gradient fixed value to obtain the second updated phase adjustment parameter, and according to the second updated phase adjustment parameter, the first polarized light and the second polarized light are phase-adjusted respectively to obtain a second updated synthetic light beam, and the second updated electric energy signal generated by the photoelectric conversion device based on the photoelectric conversion of the second updated synthetic light beam is collected to determine whether the difference between the electric energy value corresponding to the second updated electric energy signal and the target electric energy value is less than the preset threshold value; if it is determined that the difference between the electric energy value corresponding to the second updated electric energy signal and the target electric energy value is less than the preset threshold value, it is determined that the electric energy signal generated by the photoelectric conversion device meets the target electric energy condition.

[0063] It should be noted here that if the second updated electric energy signal still cannot meet the target electric energy conditions, that is, the difference between the electric energy value corresponding to the second updated electric energy signal and the target electric energy value is still not less than the preset threshold, this scheme will continue to update and adjust the phase adjustment parameters based on the gradient fixed value until the updated electric energy signal generated by the photoelectric conversion device based on the synthetic light beam conversion meets the target electric energy conditions.

[0064] As another possible implementation, the gradient value of the parameter adjustment set in this solution can also be determined based on two power signals of two adjacent adjustments.

[0065] In the case where the above-mentioned gradient value is determined based on two electric energy signals adjusted twice adjacently, this scheme can first calculate the electric energy difference between the first electric energy signal and the second electric energy signal to obtain the gradient value of the parameter adjustment, and then adjust the initial phase adjustment parameter according to the target polarity adjustment direction based on the gradient value (electric energy difference) to obtain the first updated phase adjustment parameter, and according to the first updated phase adjustment parameter, respectively adjust the phase of the first polarized light and the second polarized light to obtain the first updated synthetic light beam, collect the first updated electric energy signal generated by the photoelectric conversion device based on the first updated synthetic light beam for photoelectric conversion, and judge whether the difference between the electric energy value corresponding to the first updated electric energy signal and the target electric energy value is less than the preset threshold; if it is determined that the difference between the electric energy value corresponding to the first updated electric energy signal and the target electric energy value is less than the preset threshold, it is determined that the electric energy signal generated by the photoelectric conversion device meets the target electric energy condition.

[0066] If it is determined that the difference between the electric energy value corresponding to the first updated electric energy signal and the target electric energy value is not less than the preset threshold value, this scheme obtains an updated gradient value based on the first updated electric energy signal and the electric energy difference between the first electric energy difference and the second electric energy difference, whichever has the smaller difference; according to the updated gradient value, the first updated phase adjustment parameter is adjusted according to the target polarity adjustment direction to obtain the second updated phase adjustment parameter; according to the second updated phase adjustment parameter, the first polarized light and the second polarized light are phase-adjusted respectively to obtain a second updated synthetic light beam, and the second updated electric energy signal generated by the photoelectric conversion device based on the second updated synthetic light beam is collected to determine whether the difference between the electric energy value corresponding to the second updated electric energy signal and the target electric energy value is less than the preset threshold value; if it is determined that the difference between the electric energy value corresponding to the second updated electric energy signal and the target electric energy value is less than the preset threshold value, it is determined that the electric energy signal generated by the photoelectric conversion device meets the target electric energy condition.

[0067] It should be noted here that if the second updated electric energy signal still cannot meet the target electric energy conditions, that is, the difference between the electric energy value corresponding to the second updated electric energy signal and the target electric energy value is still not less than the preset threshold, this scheme will continue to use the electric energy difference between the updated electric energy signal obtained this time and the updated electric energy signal obtained by the last adjustment as the updated gradient value, and continuously update and adjust the phase adjustment parameters until the updated electric energy signal generated by the photoelectric conversion device based on the synthetic light beam conversion meets the target electric energy conditions.

[0068] The photoelectric conversion adjustment method designed above uses polarization splitting to split the target light beam into two polarized lights with mutually perpendicular propagation directions, and phase-adjusts the first polarized light and the second polarized light respectively, and then synthesizes and transmits them to the photoelectric conversion device. The phase adjustment parameters are adjusted by collecting the electric energy signal generated by the photoelectric conversion device based on the synthetic light field until the electric energy signal generated by the photoelectric conversion device meets the target electric energy conditions. Therefore, the photoelectric conversion adjustment method designed in this scheme not only corrects the polarization on the basis of phase correction through the synthetic light field generated by polarization splitting and phase adjustment, thereby compensating for the influence of turbulence, and based on polarization correction, it also increases the laser transmission efficiency in foggy conditions; at the same time, the electric energy signal generated by the photoelectric conversion device based on the synthetic light field is used as a feedback indicator for phase adjustment, so that the electric energy signal of the photoelectric conversion device can reflect the degree of matching between the phase of the light beam and the photoelectric conversion device, and then the electric energy signal generated by the photoelectric conversion device can be achieved to the optimal state through phase adjustment, thereby improving the absorption efficiency of the photoelectric conversion device for laser.

[0069] The present application also provides a photoelectric conversion regulation system, which can implement the photoelectric conversion regulation method process described above, such as Figure 3 As shown, the photoelectric conversion regulation system includes a first polarization beam splitting device 10, a first light field modulator 20, a second light field modulator 30, a second polarization beam splitting device 40, and a control device 50. Specifically, the first polarization beam splitting device 10 and the second polarization beam splitting device 40 can be polarization beam splitters. Of course, other optical elements capable of polarization beam splitting, such as polarizing prisms, polarizing glass plates, etc., can also be used. The first light field modulator 20 and the second light field modulator 30 can be deformable mirrors. Of course, other optical elements capable of achieving light beam phase modulation based on voltage changes, such as liquid crystal phase modulators, acousto-optic modulators, or micromirror arrays, etc., can also be used.

[0070] In the above-designed photoelectric conversion regulation system, the first polarization beam splitting device 10 can receive a target light beam and perform polarization splitting on the received target light beam to obtain a first polarized light and a second polarized light, wherein the two polarized lights obtained by the polarization splitting of the first polarization beam splitting device 10 can be s-polarized light and p-polarized light whose propagation directions are perpendicular to each other.

[0071] The first light field modulator 20 can receive the first polarized light, and then perform phase adjustment on the first polarized light according to the first preset phase adjustment parameter to obtain the first phase-adjusted light. The second light field modulator 30 receives the second polarized light, and then perform phase adjustment on the second polarized light according to the first preset phase adjustment parameter to obtain the second phase-adjusted light.

[0072] The second polarization beam splitting device 40 can receive the first phase-adjusted light and the second phase-adjusted light, and combine the first phase-adjusted light and the second phase-adjusted light into a first synthetic light beam and transmit it to the photoelectric conversion device. The photoelectric conversion device performs photoelectric conversion based on the first synthetic light beam to generate a first electrical energy signal, and the control device 50 collects the first electrical energy signal generated by the photoelectric conversion device.

[0073] In the same way, the first light field modulator 20 also phase-adjusts the first polarized light according to the second preset phase adjustment parameter to obtain a third phase-adjusted light. The second light field modulator 30 receives the second polarized light, and then phase-adjusts the second polarized light according to the first preset phase adjustment parameter to obtain a fourth phase-adjusted light. The second polarization beam splitter 40 can receive the third phase-adjusted light and the fourth phase-adjusted light, and combine the third phase-adjusted light and the fourth phase-adjusted light into a second synthetic light beam and transmit it to the photoelectric conversion device. The photoelectric conversion device performs photoelectric conversion based on the second synthetic light beam to generate a second electrical energy signal, and the control device 50 collects the second electrical energy signal generated by the photoelectric conversion device.

[0074] The control device 50 also adjusts the phase adjustment parameters according to the first electric energy signal and the second electric energy signal until the electric energy signal generated by the photoelectric conversion device meets the target electric energy conditions. The process of adjusting the phase adjustment parameters by the control device is similar to the process of the photoelectric conversion adjustment method described above, and will not be repeated here.

[0075] The photoelectric conversion adjustment system designed above first splits the target light beam into two polarized light beams with mutually perpendicular propagation directions through a first polarization beam splitter. The first light field modulator and the second light field modulator respectively perform phase adjustment on the first polarized light and the second polarized light. The phase-adjusted light beams are synthesized and transmitted to the photoelectric conversion device through a second polarization fractionator. The control device adjusts the phase adjustment parameters by collecting the electric energy signal generated by the photoelectric conversion device based on the synthesized light field until the electric energy signal generated by the photoelectric conversion device meets the target electric energy condition. Therefore, the photoelectric conversion adjustment system designed in this scheme not only corrects the phase of the synthesized light field generated by polarization beam splitting and phase adjustment, but also corrects the polarization, thereby compensating for the influence of turbulence. The polarization correction also increases the laser transmission efficiency in foggy conditions. At the same time, the electric energy signal generated by the photoelectric conversion device based on the synthesized light field is used as a feedback indicator for phase adjustment. In this way, the electric energy signal of the photoelectric conversion device can reflect the degree of phase matching between the light beam and the photoelectric conversion device. Then, through phase adjustment, the electric energy signal generated by the photoelectric conversion device can be optimized, thereby improving the absorption efficiency of the photoelectric conversion device for laser light.

[0076] The present application also provides a photoelectric conversion system, such as Figure 4As shown, the photoelectric conversion system includes a light beam emitting device A, a photoelectric conversion device B, and a photoelectric conversion adjustment system C as described in any of the optional embodiments described above. The light beam emitting device A and the photoelectric conversion device B can be electrically connected to a control device 50. The control device 50 can control the light beam emitting device A to emit a target light beam toward the first polarization beam splitting device 10. The photoelectric conversion device B can convert the received composite light beam into a corresponding electrical energy signal. The control device 50 can collect the electrical energy signal generated by the photoelectric conversion device and adjust it based on the photoelectric conversion adjustment method described above, so that the electrical energy signal generated by the photoelectric conversion device reaches the optimal state. Specifically, the light beam emitting device A can be a laser emitter, and the photoelectric conversion device B can be a photovoltaic panel. Specifically, the photoelectric conversion device B can be a photovoltaic panel with a photovoltaic unit array, such as a 3×3 array of photovoltaic panels. Of course, the photoelectric conversion device B can also use other components that can convert light energy into electrical energy, such as photochemical cells.

[0077] The photoelectric conversion system designed above includes the photoelectric conversion regulation system described above. Therefore, the designed photoelectric conversion system, on the one hand, corrects the polarization on the basis of phase correction by using the synthetic light field generated by polarization splitting and phase adjustment, thereby compensating for the influence of turbulence, and the laser transmission efficiency in foggy conditions is also increased based on polarization correction; at the same time, the electric energy signal generated by the photoelectric conversion device based on the synthetic light field is used as a feedback indicator of phase adjustment, so that the electric energy signal of the photoelectric conversion device can reflect the degree of matching between the phase of the light beam and the photoelectric conversion device, and then the electric energy signal generated by the photoelectric conversion device can be achieved in the optimal state through phase adjustment, thereby improving the absorption and conversion efficiency of the photoelectric conversion system for laser.

[0078] This solution verifies the effectiveness of the above-mentioned photoelectric conversion system through the following experiments: Turbulence correction experiment: Figure 5 As shown, a turbulence sheet is introduced into the optical path of the photoelectric conversion system as a device to simulate atmospheric turbulence and correct the distortion caused by it, wherein, Figure 5 (a) is the spot pattern before correction, Figure 5 (b) is the spot diagram after correction. By comparison, it is found that the size of the far-field spot after correction is smaller than that before correction, and the brightness of the central area of ​​the far-field spot after correction is also brighter than before correction. This verifies the ability of the photoelectric conversion system designed in this scheme to correct turbulence.

[0079] Fog simulation experiment: This solution adds an atomizer to the optical path of the photoelectric conversion system as a device to simulate a foggy environment. The distortion produced is corrected, and the data in Table 1 below is obtained: Table 1 System voltage after optimization under different fog concentrations

[0080] As can be seen from Table 1 above, the vector is better than the scalar in foggy environments. As the fog concentration increases, the effect of increasing the quantity is better. This verifies that this scheme can adaptively generate the optimal vector beam that meets the current state.

[0081] Light spot uniformity experiment: This scheme uses the solar panel voltage as feedback to observe the light spot changes, and uses a CCD camera to record the light spot images before and after correction to obtain Figure 6 The spot diagram and Figure 7 The photoelectric conversion efficiency diagram, from Figure 6 and Figure 7 It can be seen that the light intensity of the entire beam coverage area before and after correction is close to the optimal operating range of the solar cell, avoiding local excessive or insufficient light intensity, and as the number of iterations increases, the voltage value of the solar panel increases.

[0082] Rotating solar panel experiment: This solution changes the receiving angle of the solar panel and uses the obtained voltage as an evaluation indicator to conduct experiments. The absorbed power of the solar panel at different incident angles is recorded. The rotation step of the solar panel is 5°, and it is rotated from 35° to 80°. A total of 10 experiments are performed to compare the normalized barrel power with and without polarization correction. The results are as follows: Figure 8 The results of the rotating solar panel experiment are shown in Figure 2.

[0083] from Figure 8 It can be seen that the correction effect of vector light is better than directly adding two scalar lights, which verifies the superiority of vector light.
