Description

Technical Field

[0001] This invention relates to the field of automation control technology, and in particular to an intrinsic frequency online adjustment system, method, device, medium, program, intrinsic frequency online adjustment device, and intrinsic frequency online adjustment system parameter adjustment method. Background Technology

[0002] The intrinsic frequency is a core parameter of the equipment. With a fixed light source wavelength, its value is uniquely determined by the length of the core sensitive component. Many equipment modulation parameters, such as modulation signal frequency, modulation depth, and number of sampling points, are directly related to the intrinsic frequency. Therefore, the accuracy of the intrinsic frequency has a crucial impact on equipment performance.

[0003] During equipment commissioning, the standard procedure involves measuring the intrinsic frequency of the core sensitive components at room temperature, using this value to set the circuit commissioning parameters, and then fixing these parameters after commissioning. However, this approach does not consider the ambient temperature fluctuations in actual applications. The temperature range of the equipment's operating environment can typically reach 100°C. During this process, the equivalent length of the core sensitive components will change with temperature, causing the intrinsic frequency to deviate from the initial set value. When the intrinsic frequency changes too much, it can lead to a series of negative impacts, such as distortion of the equipment's output signal, decreased modulation efficiency and increased residual modulation error, as well as deterioration of closed-loop stability leading to poor dynamic response.

[0049] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0050] It should be noted that the terms "first," "second," and "target," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0051] Example 1

[0052] Figure 1 This is a schematic diagram of an intrinsic frequency online adjustment system provided in Embodiment 1 of the present invention. The structure of the intrinsic frequency online adjustment system 100 includes: at least one electromagnetic coil 110, an electromagnetic coil driving circuit 120, an optical fiber loop 130, and a beam processing module 140; wherein:

[0053] The electromagnetic coil driving circuit 120 is electrically connected to the electromagnetic coil 110 and is used to provide a target driving current to the electromagnetic coil 110 so as to change the magnetic field of the electromagnetic coil 110 through the target driving current.

[0054] The target driving current can be generated by the electromagnetic coil driving circuit 120 and is used to ensure that the intrinsic frequency of the optical fiber loop is maintained at the target intrinsic frequency.

[0055] In this embodiment of the invention, the electromagnetic coil driving circuit 120 is electrically connected to at least one electromagnetic coil 110. The electromagnetic coil driving circuit 120 can provide a target driving current to the at least one electromagnetic coil 110, thereby enabling the magnetic field generated by the electromagnetic coil 110 to change with the magnitude of the target driving current. It is understood that when the intrinsic frequency online adjustment system 100 includes multiple electromagnetic coils 110, the multiple electromagnetic coils 110 are electrically connected to the electromagnetic coil driving circuit 120 in series.

[0056] The electromagnetic coil 110 is used to adjust the refractive index of the optical fiber loop 130 by generating a magnetic field.

[0057] Changes in ambient temperature can alter the intrinsic frequency of an optical fiber loop. This is fundamentally because temperature fluctuations cause variations in the transit time of light within the loop. Therefore, compensating for the intrinsic frequency essentially involves adjusting the transit time of light within the loop. Given a fixed fiber length, this can be achieved by controlling the effective refractive index of the light within the fiber, ultimately enabling online dynamic adjustment of the intrinsic frequency.

[0058] Specifically, when the electromagnetic coil driving circuit 120 changes the magnetic field of the electromagnetic coil 110 through the target driving current, the electromagnetic coil 110 can also adjust the refractive index of the optical fiber loop 130 through the generated magnetic field.

[0059] It should be noted that, in order to prevent the magnetic field generated by the electromagnetic coil 110 from affecting the rest of the intrinsic frequency online adjustment system 100, a magnetic shielding structure needs to be placed on the outside of the electromagnetic coil 110 to prevent magnetic field leakage.

[0060] Figure 2 This is a schematic diagram of a solid polarization-maintaining photonic crystal fiber provided in Embodiment 1 of the present invention. The polarization-maintaining photonic crystal fiber has a porous structure, in which functional materials can be filled to adjust its light guiding properties.

[0061] Optionally, the fiber optic loop 130 can be adopted as follows: Figure 2 The image shows a solid-core polarization-maintaining photonic crystal fiber. The outer layer (201) is the fiber cladding, the inner layer (203) is the fiber core, and the circular structure (202) is an air hole that can be filled with functional materials. It should be noted that... Figure 2 This is merely an illustrative example of the fiber structure in a fiber loop, and the embodiments of the present invention do not limit the specific structure and dimensions of the photonic crystal fiber. The filling functional material must be a material whose refractive index is sensitive to the physical field, i.e., a physical field-sensitive optical material, such as a magnetohydrodynamic material, etc. The embodiments of the present invention do not limit the specific type of physical field-sensitive optical material. Therefore, the air holes inside the fiber loop 130 can be filled with a physical field-sensitive optical material of a predetermined length.

[0062] Magnetofluids are stable colloids formed by dispersing nanoscale magnetic particles in a carrier, and their refractive index can be modulated by changes in an applied magnetic field. Based on this property, magnetofluid material can be filled at both ends of a photonic crystal fiber loop, and electromagnetic coils can be configured to apply a magnetic field. When temperature changes cause a shift in the intrinsic frequency of the fiber loop, the magnetic field strength can be altered by adjusting the driving current of the electromagnetic coils, thereby controlling the refractive index of the magnetofluid material and ultimately changing the effective refractive index of the fiber core. The transit time of light in the fiber will adjust with the change in effective refractive index, thus achieving precise compensation and dynamic control of the intrinsic frequency of the fiber loop.

[0063] The fiber loop 130 passes through at least one of the electromagnetic coils 110, and the ends of the two extended branches of the fiber loop 130 are connected to the beam processing module 140 for maintaining the target intrinsic frequency of the target device based on the current refractive index.

[0064] The target device can be a device whose intrinsic frequency is to be adjusted online. For example, the target device may include, but is not limited to, a fiber optic gyroscope or a fiber optic loop temperature sensor; this embodiment of the invention does not limit the specific type of the target device. The target intrinsic frequency can be the intrinsic frequency that the target device needs to maintain unchanged. The current refractive index can be the refractive index of the fiber loop 130 under the current target driving current.

[0065] Specifically, the fiber optic loop 130 can pass through at least one electromagnetic coil 110, and the ends of the branching ends of the fiber optic loop 130 are connected to the beam processing module 140. The fiber optic loop 130 can adjust its refractive index through the magnetic field generated by the electromagnetic coil 110 to maintain the target intrinsic frequency of the target device based on the current refractive index.

[0066] The beam processing module 140 is used to perform beam splitting processing on the target optical signal and adjust the phase of the two split beams; the beam processing module 140 is also used to perform beam combining processing on the two split beams that propagate back from the optical fiber loop 130.

[0067] The target optical signal can be an optical signal transmitted externally to the beam processing module 140.

[0068] Specifically, the beam processing module 140 can split the received target optical signal into two beams of equal power to avoid subsequent signal distortion or phase adjustment deviation caused by power differences, thus providing a stable signal source for closed-loop control. After obtaining two beams of equal power, the beam processing module 140 can adjust the phase of the two beams to achieve closed-loop feedback and dynamic adjustment of signal transmission. The beam processing module 140 can also combine the two split beams returning from the back propagation of the fiber loop 130 to obtain an interference optical signal.

[0069] In an optional embodiment of the present invention, the beam processing module 140 may include an optical fiber beam splitter 141 and a waveguide modulator 142; wherein: the optical fiber beam splitter 141 is connected to the waveguide modulator 142 and is used to perform power attenuation processing on the target optical signal to obtain a first target optical signal, and to output the first target optical signal to the waveguide modulator 142; the waveguide modulator 142 is connected to the ends of the two extended branches of the optical fiber loop 130 and is used to perform beam splitting processing on the first target optical signal, adjust the phase of the beam splitting to obtain clockwise beam splitting light and counterclockwise beam splitting light, and transmit the clockwise beam splitting light and the counterclockwise beam splitting light to the optical fiber loop 130; the waveguide modulator 142 is also used to perform beam combining processing on the clockwise beam splitting light and the counterclockwise beam splitting light that propagate back from the optical fiber loop 130, and to transmit the combined interference optical signal to the optical fiber beam splitter 141.

[0070] The first target optical signal can be an optical signal obtained after power attenuation processing of the target optical signal by the fiber beam splitter 141. The clockwise beam splitting light can be a beam of light propagating clockwise along the fiber loop 130 after beam splitting processing by the waveguide modulator 142. The counterclockwise beam splitting light can be a beam of light propagating counterclockwise along the fiber loop 130 after beam splitting processing by the waveguide modulator 142. The interference optical signal can be an optical signal obtained by combining the clockwise and counterclockwise beam splitting lights that propagate back from the fiber loop 130.

[0071] Figure 3 This is a schematic diagram of the structure of a beam processing module provided in Embodiment 1 of the present invention. Figure 3 As shown, in this embodiment of the invention, the beam processing module 140 may include, but is not limited to, an optical fiber beam splitter 141 and a waveguide modulator 142. This embodiment of the invention does not limit the specific devices included in the beam processing module. For example, the optical fiber beam splitter 141 may include, but is not limited to, a polarization-maintaining optical fiber beam splitter, and the waveguide modulator 142 may include, but is not limited to, a Y-waveguide modulator.

[0072] The fiber optic beam splitter 141 and the waveguide modulator 142 are connected by an optical fiber. The fiber optic beam splitter 141 can perform power attenuation processing on the received target optical signal to obtain the first target optical signal, and then send the first target optical signal to the waveguide modulator 142.

[0073] Waveguide modulator 142 is connected to the ends of the two extended branches of fiber loop 130, respectively, and can perform beam splitting processing on the first target optical signal, while precisely adjusting the phase of the split beam to obtain clockwise and counterclockwise split beams. After phase adjustment, waveguide modulator 142 can transmit the clockwise split beam along the clockwise direction of fiber loop 130, and transmit the counterclockwise split beam along the counterclockwise direction of fiber loop 130.

[0074] After being transmitted through the fiber optic loop 130, the clockwise and counterclockwise split beams can propagate in the opposite direction along the original path and return to the waveguide modulator 142. Furthermore, the waveguide modulator 142 can utilize the phase difference between the returning clockwise and counterclockwise split beams to perform beam combining, and then transmit the resulting interference signal to the fiber optic beam splitter 141.

[0075] This invention, through an online intrinsic frequency adjustment system, incorporates at least one electromagnetic coil, an electromagnetic coil driving circuit, an optical fiber loop, and a beam processing module to achieve online adjustment of the intrinsic frequency of an optical fiber loop. The electromagnetic coil driving circuit is electrically connected to the electromagnetic coil and provides a target driving current to change the magnetic field of the electromagnetic coil. The electromagnetic coil adjusts the refractive index of the optical fiber loop using the generated magnetic field. Simultaneously, the optical fiber loop passes through at least one electromagnetic coil, and the ends of the extended branches at both ends of the optical fiber loop are connected to the beam processing module to maintain the target intrinsic frequency of the target device based on the current refractive index. The beam processing module is used to split the target optical signal and adjust the phase of the two split beams, and to combine the two split beams propagating back from the optical fiber loop. This solution overcomes the shortcomings of existing technologies where the intrinsic frequency of the optical fiber loop is easily affected by ambient temperature, enabling online adjustment of the intrinsic frequency of the optical fiber loop across the entire temperature range, thereby improving the environmental adaptability of the equipment.

[0076] Example 2

[0077] Figure 4 This is a schematic diagram of an intrinsic frequency online adjustment device provided in Embodiment 2 of the present invention. The structure of the intrinsic frequency online adjustment device 200 includes: an intrinsic frequency online adjustment system 100, a light source module 210, a photodetector 220, and a modulation and demodulation circuit 230; wherein:

[0078] The light source module 210 is connected to the beam processing module 140 in the intrinsic frequency online adjustment system 100, and is used to generate the target light signal and transmit the target light signal to the beam processing module 140.

[0079] In this embodiment of the invention, the intrinsic frequency online adjustment device 200 may include, but is not limited to, the intrinsic frequency online adjustment system 100, the light source module 210, the photodetector 220, and the modulation and demodulation circuit 230, etc. This embodiment of the invention does not limit the specific devices included in the intrinsic frequency online adjustment device 200. For example, the intrinsic frequency online adjustment device 200 may include, but is not limited to, a fiber optic gyroscope or a fiber optic cavity temperature sensor, etc., as long as the device requires intrinsic frequency online adjustment. This embodiment of the invention does not limit the specific type of the intrinsic frequency online adjustment device 200.

[0080] Figure 5 This is a schematic diagram of a fiber optic gyroscope provided in Embodiment 2 of the present invention. In a specific example, such as... Figure 5 As shown, the fiber optic gyroscope includes a light source module 210, a photodetector 220, a modulation and demodulation circuit 230, a fiber optic beam splitter 141, a waveguide modulator 142, two electromagnetic coils 110, an electromagnetic coil drive circuit 120, and a fiber optic loop 130.

[0081] In the intrinsic frequency online adjustment device 200, the light source module 210 and the beam processing module 140 in the intrinsic frequency online adjustment system 100 are connected via optical fiber. The light source module 210 can generate a target optical signal and transmit the target optical signal to the beam processing module 140. For example, the light source module 210 may include, but is not limited to, an ASE (Amplified Spontaneous Emission) light source, etc. The embodiments of the present invention do not limit the specific devices included in the light source module 210.

[0082] The photodetector 220 is connected to the beam processing module 140 and is used to receive the interference light signal output by the beam processing module 140, convert the interference light signal into a target electrical signal, and transmit the target electrical signal to the modulation and demodulation line 230. The modulation and demodulation line 230 is electrically connected to the photodetector 220 and is used to demodulate the target electrical signal.

[0083] The target electrical signal can be an electrical signal obtained by converting an interference optical signal.

[0084] Specifically, the photodetector 220 is connected to the beam processing module 140 via optical fiber, and is also electrically connected to the modulation / demodulation line 230. The photodetector 220 can receive the interference light signal output from the beam processing module 140 and convert it into a target electrical signal. Further, the photodetector 220 can transmit the target electrical signal to the modulation / demodulation line 230. The modulation / demodulation line 230 can demodulate the received target electrical signal. For example, assuming the intrinsic frequency online adjustment device is a fiber optic gyroscope, the target electrical signal is the electrical signal converted from the rotational speed information carried by the interference light signal.

[0085] This invention, through the inclusion of an online intrinsic frequency adjustment system, a light source module, a photodetector, and a modulation / demodulation circuit in an online intrinsic frequency adjustment device, achieves online adjustment of the device's intrinsic frequency. The light source module is connected to the beam processing module within the online intrinsic frequency adjustment system, generating a target optical signal and transmitting it to the beam processing module. The photodetector, connected to the beam processing module, receives the interference optical signal output by the beam processing module, converts it into a target electrical signal, and transmits the target electrical signal to the modulation / demodulation circuit. The modulation / demodulation circuit is electrically connected to the photodetector for demodulating the target electrical signal. This solution overcomes the limitation of existing technologies where the intrinsic frequency of the fiber optic loop is easily affected by ambient temperature, enabling online adjustment of the fiber optic loop's intrinsic frequency across the entire temperature range, thereby improving the device's environmental adaptability.

[0086] Example 3

[0087] Figure 6 This is a flowchart of an online intrinsic frequency adjustment method provided in Embodiment 3 of the present invention. This embodiment is applicable to situations where the intrinsic frequency of an online intrinsic frequency adjustment system is adjusted online according to changes in ambient temperature. This method can be executed by an online intrinsic frequency adjustment system, which can be implemented in software and / or hardware and is generally integrated into an electronic device, which can be the online intrinsic frequency adjustment system. Correspondingly, as... Figure 6 As shown, the method includes the following operations:

[0088] S310: Obtain the current ambient temperature and temperature-driven current mapping relationship.

[0089] Here, the current ambient temperature can be the temperature of the operating environment of the intrinsic frequency online adjustment system. The temperature-driven current mapping relationship can be the correspondence between the ambient temperature and the driving current in the electromagnetic coil driving circuit.

[0090] In this embodiment of the invention, in order to achieve online adjustment of the intrinsic frequency according to changes in ambient temperature, the temperature-driven current mapping relationship and the current ambient temperature can be obtained first.

[0091] S320. Query the target driving current that matches the current ambient temperature according to the temperature driving current mapping relationship.

[0092] The target drive current can be a drive current that matches the current ambient temperature, determined according to the temperature drive current mapping relationship.

[0093] Accordingly, after obtaining the mapping relationship between the current ambient temperature and the temperature-driven current, the target driving current that matches the current ambient temperature can be determined based on the mapping relationship.

[0094] S330. Adjust the current drive current of the electromagnetic coil drive circuit in the intrinsic frequency online adjustment system to the target drive current so that the intrinsic frequency of the intrinsic frequency online adjustment system remains unchanged.

[0095] The current driving current can be the driving current in the electromagnetic coil driving circuit at the current moment.

[0096] Accordingly, after querying the target drive current matching the current ambient temperature based on the temperature-driven current mapping relationship, the current drive current of the electromagnetic coil drive circuit in the intrinsic frequency online adjustment system can be dynamically adjusted to accurately calibrate it to the target drive current. Through this closed-loop adjustment operation, the drift effect caused by changes in ambient temperature on the intrinsic frequency of the intrinsic frequency online adjustment system can be compensated in real time, thereby ensuring that the intrinsic frequency of the intrinsic frequency online adjustment system remains stable within the preset standard value range.

[0097] Therefore, the online intrinsic frequency adjustment method provided in this invention adjusts the magnetic field generated by the electromagnetic coil by changing the driving current of the electromagnetic coil, thereby adjusting the intrinsic frequency of the optical fiber loop according to the change of the magnetic field. This method not only enables online dynamic adjustment of the intrinsic frequency, greatly improving the flexibility of equipment use, but also accurately matches the frequency requirements under different operating conditions, effectively ensuring the working stability of the optical fiber loop, while significantly reducing the maintenance cost and operational complexity of the equipment.

[0098] The intrinsic frequency online adjustment system of this invention obtains the mapping relationship between the current ambient temperature and the temperature-driven current, and queries the target driving current matching the current ambient temperature based on the mapping relationship. After determining the target driving current, the current driving current of the electromagnetic coil driving circuit in the intrinsic frequency online adjustment system is adjusted to the target driving current, so that the intrinsic frequency of the intrinsic frequency online adjustment system remains unchanged. The above solution solves the problem that the intrinsic frequency of the optical fiber loop is easily affected by the ambient temperature and drifts in the prior art, and can realize the online adjustment of the intrinsic frequency of the optical fiber loop across the entire temperature range, thereby improving the environmental adaptability of the equipment.

[0100] Figure 7 This is a flowchart of a parameter tuning method for an online intrinsic frequency adjustment system provided in Embodiment 4 of the present invention. This embodiment is applicable to situations where the parameters of an online intrinsic frequency adjustment system are determined to adjust the intrinsic frequency of the system online. This method can be executed by a parameter tuning device for the online intrinsic frequency adjustment system. This device can be implemented in software and / or hardware and is generally integrated into an electronic device. This electronic device can be a terminal device or a server device, as long as it can execute the parameter tuning method for the online intrinsic frequency adjustment system. The embodiments of the present invention do not limit the specific type of electronic device. Accordingly, as... Figure 7 As shown, the method includes the following operations:

[0101] S410. Obtain the target frequency value of the intrinsic frequency of the test equipment and the temperature-current correlation transformation test data of the non-circuit structure in the intrinsic frequency online adjustment system.

[0102] The test equipment can be an online frequency adjustment device whose parameters are to be adjusted. The target frequency value can be the preset intrinsic frequency value that the test equipment is expected to achieve. The temperature-current correlation transformation test data can be the test data showing the correspondence between the ambient temperature and the drive current in the test equipment when the test equipment is maintained at a certain intrinsic frequency value.

[0103] In this embodiment of the invention, to achieve parameter adjustment of the online intrinsic frequency adjustment system, the non-circuit structure part of the online intrinsic frequency adjustment system can be placed in a temperature chamber. By adjusting the temperature chamber temperature, the target frequency value of the intrinsic frequency of the test equipment and the temperature-current correlation transformation test data of the non-circuit structure in the online intrinsic frequency adjustment system when the test equipment is maintained at a certain intrinsic frequency value can be obtained.

[0104] In a specific example, the components of an online intrinsic frequency adjustment device, excluding the electromagnetic coil drive circuit and the modulation / demodulation circuit, can be placed in a temperature chamber.

[0105] In an optional embodiment of the present invention, obtaining the target frequency value of the intrinsic frequency of the test device may include: changing the test drive current of the electromagnetic coil drive circuit in the intrinsic frequency online adjustment system to obtain the intrinsic frequency variation range of the test device; and determining the target frequency value of the intrinsic frequency of the test device based on the intrinsic frequency variation range of the test device.

[0106] The test drive current can be the drive current of the electromagnetic coil drive circuit in the online intrinsic frequency adjustment system during parameter adjustment. The intrinsic frequency variation range can be the range of numerical fluctuations in the intrinsic frequency of the test equipment as the temperature of the chamber changes.

[0107] In this embodiment of the invention, when obtaining the target frequency value of the intrinsic frequency of the test equipment, the test drive current of the electromagnetic coil drive circuit in the intrinsic frequency online adjustment system can be gradually increased until the intrinsic frequency no longer changes under normal temperature conditions, such as 25 degrees Celsius, to obtain the intrinsic frequency variation range of the test equipment. Furthermore, a value can be selected from the intrinsic frequency variation range of the test equipment as the target frequency value; for example, the median value of the intrinsic frequency variation range can be selected as the target frequency value.

[0108] S420. Establish a mapping relationship between the target frequency value of the intrinsic frequency and the temperature-current correlation transformation test data to obtain the temperature-driven current mapping relationship corresponding to the test equipment; wherein, the temperature-driven current mapping relationship is used for online adjustment of the intrinsic frequency of the target equipment.

[0109] The target device can be an online frequency adjustment device whose parameters have been adjusted.

[0110] Accordingly, after obtaining the target frequency value of the intrinsic frequency of the test equipment and the temperature-current correlation transformation test data of the non-circuit structure in the intrinsic frequency online adjustment system, the temperature-current correlation transformation test data corresponding to the target frequency value of the intrinsic frequency can be found and used as the temperature-driven current mapping relationship for the test equipment. Furthermore, the intrinsic frequency of the target equipment can be adjusted online based on the temperature-driven current mapping relationship.

[0111] Optionally, after obtaining the temperature-driven current mapping relationship corresponding to the test equipment, the modulation signal frequency, modulation depth, and number of sampling points of the test equipment can be determined based on the target frequency value of the intrinsic frequency.

[0112] In an optional embodiment of the present invention, before establishing the mapping relationship between the target frequency value of the intrinsic frequency and the temperature-current correlation transformation test data, the method may further include: if it is determined that the intrinsic frequency of the test equipment cannot be adjusted to the target frequency value, adjusting the filling length of the filling material in the fiber loop of the intrinsic frequency online adjustment system, and returning to perform the operation of obtaining the target frequency value of the intrinsic frequency of the test equipment and the temperature-current correlation transformation test data of the non-circuit structure in the intrinsic frequency online adjustment system, until it is determined that the intrinsic frequency of the test equipment is adjusted to the target frequency value.

[0113] Specifically, if the intrinsic frequency of the test equipment cannot be adjusted to the target frequency value, it is necessary to increase the filling length of the filling material in the fiber optic loop of the intrinsic frequency online adjustment system to expand the range of intrinsic frequency variation of the test equipment, and then return to perform the operation of obtaining the target frequency value of the intrinsic frequency of the test equipment and the temperature-current correlation transformation test data of the non-circuit structure in the intrinsic frequency online adjustment system, until it is determined that the intrinsic frequency of the test equipment can be adjusted to the target frequency value.

[0114] This invention, through obtaining the target frequency value of the intrinsic frequency of the test equipment and the temperature-current correlation transformation test data of the non-circuit structure in the intrinsic frequency online adjustment system, establishes a mapping relationship between the target frequency value and the temperature-current correlation transformation test data to obtain the temperature-driven current mapping relationship corresponding to the test equipment. This allows for online adjustment of the intrinsic frequency of the target equipment based on the temperature-driven current mapping relationship. This solution overcomes the shortcomings of existing technologies where the intrinsic frequency of the optical fiber loop is easily affected by ambient temperature and drifts. It enables online adjustment of the intrinsic frequency of the optical fiber loop across the entire temperature range, thereby improving the environmental adaptability of the equipment.

[0115] The collection, storage, use, processing, transmission, provision, and disclosure of user personal information in this technical solution comply with relevant laws and regulations and do not violate public order and good morals.

[0116] It should be noted that all information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for display, data used for analysis, etc.) involved in this disclosure are information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of the relevant data comply with the relevant laws, regulations and standards of the relevant regions.
