[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0033] The interferometric fiber optic gyroscope is the first generation of fiber optic gyroscopes, which was developed the earliest and has the most mature technology. It uses a multi-turn fiber coil in the cavity to draw out two beams of light that propagate in opposite directions, and uses interferometric measurement technology to convert the light phase measurement into the measurement of light intensity. The interferometric fiber optic gyroscope can be used as an angular velocity sensor, that is, according to theoretical derivation, the relationship between the output light intensity of the photodetector and the rotational angular velocity Ω can be obtained, and then the rotational angular velocity Ω can be inversely calculated by testing the output light intensity of the photodetector. It can be seen that the interferometric fiber optic gyroscope can be used to measure the rotational angular velocity.
[0034] In an interferometric fiber gyroscope, the light beam generated by the light source propagates in free space to the beam splitter, and then converges into the optical fiber through a collimating lens. However, the alignment and operation of converging light from free space to the optical fiber are difficult, resulting in low accuracy in measuring the rotational angular velocity.
[0035] In view of this, an embodiment of the present invention provides a rotating fiber ring interferometer, comprising: a light source, a fiber coupler, a fiber ring, a photodetector, a turntable and a rotation sensor, wherein the light beam emitted by the light source is transmitted to the fiber coupler, the fiber coupler divides the light beam into two coherent light beams and transmits them to the two ports of the fiber ring respectively, the two coherent light beams are transmitted in the fiber ring in a clockwise direction and a counterclockwise direction respectively, and then output from the two ports of the fiber ring to the fiber coupler for merging respectively, and the merged light is then transmitted to the photodetector, the photodetector is used to output light intensity information; at least one of the light source, the fiber coupler, the fiber ring and the photodetector is arranged on the turntable and rotates with the rotation of the turntable; the rotation sensor is arranged on the turntable and is used to output angle information or angle acceleration information when the turntable rotates. The rotating fiber ring interferometer can return the light beam generated by the light source to the fiber coupler after passing through the fiber coupler and the fiber ring respectively, and measure the output light intensity of the photodetector and the rotation angle information of the fiber ring respectively, which not only improves the accuracy of the measurement but also expands the use scenario of the instrument.
[0036] The technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0037] Figure 1 Schematic diagram of the structure of the rotating fiber ring interferometer provided by the present invention. Figure 1 As shown, the light beam emitted by the light source is transmitted to the fiber coupler, and the fiber coupler divides the light beam into two coherent light beams and transmits them to the two ports of the fiber ring respectively. The two coherent light beams are transmitted in the fiber ring in a clockwise direction and a counterclockwise direction respectively, and then output from the two ports of the fiber ring to the fiber coupler for merging respectively. The merged light is then transmitted to the photodetector, and the photodetector is used to output light intensity information; at least one of the light source, the fiber coupler, the fiber ring and the photodetector is arranged on the turntable and rotates with the rotation of the turntable; the rotation sensor is arranged on the turntable, and is used to output angle information or angle acceleration information when the turntable rotates.
[0038] It should be noted that the rotating fiber ring interferometer may include: a light source, a fiber coupler, a fiber ring, a photodetector, a rotation sensor and a turntable.
[0039] The light source has a fiber connector, which is connected to the fiber connector of port 1 of the fiber coupler. After the light emitted by the light source enters from port 1 of the fiber coupler, it is divided into two coherent lights in a ratio of 50%:50%, and output from port 2 and port 3 of the fiber coupler. The fiber connectors of port 2 and port 3 of the fiber coupler are respectively connected to the fiber connectors at both ends of the fiber ring. After the two beams of light entering the fiber ring propagate in the fiber ring in clockwise and counterclockwise directions respectively, they enter the fiber coupler from port 3 and port 2 to meet, and are output to the photodetector from port 4. The fiber connector of port 4 of the fiber coupler is connected to the fiber connector of the photodetector. The photodetector is used to test the output light intensity.
[0040] In some embodiments, the fiber ring is a multi-turn fiber coil formed by winding an optical fiber of a specific length in a preset manner, and the two ports of the fiber ring are connected with fiber connectors, which are used to connect to the two output ends of the fiber coupler. Figure 1 As shown, the optical fiber ring can be a multi-turn optical fiber ring formed by winding a long optical fiber.
[0041] Alternatively, the light source and photodetector can be powered by a DC power supply or a battery.
[0042] In some embodiments, the turntable can rotate back and forth around its axis within a preset angle range, and the rotation sensor is an angle sensor and / or an angular acceleration sensor. The angle sensor is used to output the angle information of the turntable rotation, and the angular acceleration sensor is used to output the angular acceleration information of the turntable rotation.
[0043] For example, the turntable can reciprocate around its axis within a certain angle range. An angle sensor and / or an angular acceleration sensor is placed or fixed on the turntable to test the angle or angular acceleration of the turntable rotation to obtain the rotation angular velocity by differentiation or integration.
[0044] In some embodiments, the optical fiber ring is hollow. When the optical fiber ring is disposed on the turntable, there is a certain distance between the optical fiber ring and the rotation sensor so that the optical fiber ring will not block or hinder the operation of the rotation sensor.
[0045] Exemplarily, the optical fiber ring is hollow, and when the optical fiber ring is placed on a turntable, it will not block or obstruct the angle sensor or the angular acceleration sensor.
[0046] In addition, the light source, the fiber coupler, the fiber ring, and the photodetector can be placed or fixed on the turntable alone or in any combination, and rotate with the turntable, or remain stationary without rotating. For example, when the fiber ring is placed on the turntable, the light source, the fiber coupler, and the photodetector can also be placed or fixed on the fiber ring alone or in any combination, and rotate with the fiber ring and thus rotate with the turntable.
[0047] In some embodiments, the fiber coupler is respectively connected to the light source, the photodetector, and the fiber ring via optical fibers of a target length, and the target length is less than or equal to a preset length threshold.
[0048] It should be noted that the optical fiber between the light source, the optical fiber coupler, the optical fiber ring, and the photodetector, that is, the optical fiber from the optical fiber coupler to the four ports 1-4 can be connected by a short optical fiber, so that each component can be placed or fixed on the turntable individually or in any combination, and rotate with the turntable, or remain stationary.
[0049] It is understandable that the rotating fiber ring interferometer proposed in the present invention can measure the output light intensity of the photodetector and the rotation angular velocity Ω of the fiber ring respectively after the light beam generated by the light source passes through the fiber coupler and the fiber ring and then returns to the fiber coupler, which not only improves the accuracy of the measurement but also expands the use scenarios of the instrument. For example, the output light intensity and the rotation angular velocity of the fiber ring can be used to verify whether the experimental results are consistent with the theoretical results derived from the Lorentz transformation of the special theory of relativity.
[0050] In some embodiments, at least one of the light source, the fiber coupler, the fiber ring, and the photodetector may be disposed on the turntable in a variety of ways and may be disposed according to measurement requirements or experimental needs.
[0051] In example one, the light source, the optical fiber coupler, the optical fiber ring, and the photodetector are all disposed on the turntable and rotate along with the rotation of the turntable.
[0052] It can be understood that when the first method is adopted, the relationship between the output light intensity of the photodetector and the angular velocity Ω of the optical fiber ring rotation can be tested, which can be used to verify the velocity superposition formula of the special theory of relativity, namely, the Lorentz transformation.
[0053] Example 2: The rotating fiber ring interferometer also includes a platform, which is arranged above the rotating axis of the turntable, and the platform is in a stationary state. At least one of the light source, the fiber coupler, the fiber ring, and the photodetector is arranged on the turntable. It may include: the light source is arranged on the platform, and the fiber ring, the fiber coupler, and the photodetector are all arranged on the turntable; or, the photodetector is arranged on the platform, and the light source, the fiber ring, and the fiber coupler are all arranged on the turntable.
[0054] It is understandable that, for the above two cases, due to the relative motion between the light source and the photodetector, the rotating fiber ring interferometer can also be used to test the influence of the Doppler effect on the experimental phenomenon. Among them, placing or fixing the stationary components on a stationary platform above the rotating axis of the turntable can make the rotating fiber ring interferometer work more stably and improve the accuracy of the measurement.
[0055] In some embodiments, the rotating fiber ring interferometer also includes a data acquisition device, which is respectively connected to the output end of the photodetector and the output end of the rotation sensor, and is used to collect light intensity information output by the photodetector, and angle information or angular acceleration information output by the rotation sensor; or, it also includes a data measuring device, which is respectively connected to the output end of the photodetector and the output end of the rotation sensor, and is used to measure the light intensity information output by the photodetector, and angle information or angular acceleration information output by the rotation sensor.
[0056] Exemplarily, the data acquisition device may be a data acquisition card, and the data measuring device may be an oscilloscope, wherein the oscilloscope or the data acquisition card is used to test or acquire the output signals of the angle sensor or the angular velocity sensor and the photodetector. The output signal of the photodetector may be transmitted to the oscilloscope or the data acquisition card by wire or wirelessly.
[0057] The rotating fiber ring interferometer provided by the present invention can be used to verify measurement data, formulas, etc. The use of the rotating fiber ring interferometer can facilitate measurement and verification. Detailed description will be given below.
[0058] Figure 2It is a flow chart of the data verification method based on the rotating fiber ring interferometer provided by the present invention. The rotating fiber ring interferometer adopts the above-mentioned rotating fiber ring interferometer, and the data verification method can be applied to electronic devices, which can be various types of devices with information processing capabilities during implementation. For example, the electronic device can include a personal computer, a laptop computer, a PDA or a server, etc.; the electronic device can also be a mobile terminal, for example, the mobile terminal can include a mobile phone, a car computer, a tablet computer or a projector, etc. Figure 2 As shown, the data verification method may include: Step 101: Acquire initial rotation information and initial light intensity information, wherein the initial rotation information is determined by the output value of the rotation sensor, and the initial light intensity information is the relationship between the output voltage and time determined by the output value of the photodetector.
[0059] It should be noted that the method for obtaining the initial rotation information and the initial light intensity information can be obtained by connecting the rotation sensor and the photodetector, or by obtaining them through a data acquisition device, or by obtaining them through a data measurement device. The present invention does not limit the method for obtaining the initial rotation information and the initial light intensity information.
[0060] Step 102: Obtain the relationship between the rotation angular frequency of the turntable and time according to the initial rotation information.
[0061] It should be noted that the relationship between the rotation angular frequency of the turntable and time can be obtained by fitting the initial rotation information to obtain a fitting value, and then differentiating or integrating the fitting value. Exemplarily, the angle information can be differentiated, or the angular acceleration can be integrated to obtain the value.
[0062] Step 103: Perform data verification based on the relationship between the rotation angular frequency and time, and the initial light intensity information, wherein the data verification is used to indicate whether the actual calculation result obtained by verifying the relationship between the rotation angular frequency of the turntable and time, and the initial light intensity information matches the preset theoretical result.
[0063] Exemplarily, data verification based on the relationship between the rotation angular frequency and the time variation and the initial light intensity information may be used to verify the velocity superposition formula of the special theory of relativity, i.e., the Lorentz transformation, or to test the influence of the Doppler effect on the experimental phenomenon, etc. The present invention does not limit the method for data verification based on the relationship between the rotation angular frequency and the time variation and the initial light intensity information.
[0064] It can be understood that the data verification method based on the rotating fiber ring interferometer of the present invention can improve the accuracy of data verification.
[0065] In some embodiments, the relationship between the rotation angular frequency and time is obtained by fitting the initial rotation information to obtain a fitting value, and then differentiating or integrating the fitting value. The acquisition of the relationship between the turntable rotation angular frequency and time based on the initial rotation information may include: selecting data of a target rotation period in the initial rotation information, the target rotation period including the time period in which the output of the angle sensor reciprocates from one maximum value to the next maximum value; performing multivariate linear fitting on the relationship between the output voltage and time within the target rotation period to obtain the fitting value.
[0066] For example, for the angle value measured by the angle sensor, it is necessary to differentiate the time to obtain the angular velocity. Due to experimental errors and the noise of the angle sensor, the original test data of the angle sensor has errors. If the original data is directly used to differentiate the time to calculate the angular velocity, the angular velocity will also have a large error. In this embodiment, the test value of the angle sensor is first fitted, and then the fitted value is differentiated to solve this problem. The specific steps are to select data from a rotation cycle of the angle sensor for processing. During this cycle, the output of the angle sensor reciprocates from a maximum value to the next maximum value. A multivariate linear fitting is performed on the relationship between the output voltage of the angle sensor and time t during this cycle (the output voltage of the angle sensor and , Perform linear fitting) to obtain the fitting value of the angle sensor.
[0067] It can be understood that the method of obtaining the relationship between the turntable rotation angular frequency and time according to the initial rotation information can improve the accuracy of the obtained relationship between the turntable rotation angular frequency and time, thereby improving the data verification effect.
[0068] In some embodiments, the light source, the fiber coupler, the fiber ring, and the photodetector are all disposed on the turntable and rotate with the turntable. Data verification is performed based on the relationship between the rotation angular frequency and time and the initial light intensity information. The verification may include: calculating an experimental value based on the relationship between the rotation angular frequency and time and the initial light intensity information; and verifying the velocity superposition formula of the special theory of relativity based on whether the experimental value matches the theoretical value, the theoretical value being a value derived from the velocity superposition formula of the special theory of relativity.
[0069] It should be noted that, when the fiber coupler, the fiber ring and the photodetector are all arranged on the turntable and rotate with the turntable, the experimental value is obtained according to the relationship between the rotation angular frequency and time, and the initial light intensity information, and then the theoretical value is calculated by the velocity superposition formula of the special theory of relativity. By comparing the experimental value and the theoretical value, it can be verified whether the experimental result is consistent with the theoretical result derived from the Lorentz transformation of the special theory of relativity.
[0070] It is understandable that in the above case, verifying whether the experimental results are consistent with the theoretical results derived from the Lorentz transformation of special relativity can improve the accuracy of the verification.
[0071] The following describes an exemplary application of an embodiment of the present invention in a practical application scenario.
[0072] Figure 3 FIG. 1 is a schematic diagram of the overall structure of the rotating fiber ring interferometer provided by the present invention. Figure 3 As shown, the rotating fiber ring interferometer includes: a light source, a fiber coupler, a fiber ring, a photodetector, an angle sensor or an angular acceleration sensor, a turntable, an oscilloscope or a data acquisition card.
[0073] The light source can be a laser diode with a wavelength of 1310 nm, an output power of 0.5 mW, and an FC connector. The fiber coupler can be a 2-to-2 tapered fiber coupler with an FC connector, a power ratio of 50%:50%, and the optical fibers from the fiber coupler to its four ports are single-mode optical fibers. The fiber ring is formed by a 1000 m long single-mode single-core invisible optical fiber, and the connector type is an FC connector. The outer radius R1 of the fiber ring is 10.0 cm, the inner radius R2 is 5.0 cm, and the average radius is 7.5 cm. The photodetector can be an InGaSa Pin photoelectric conversion diode with a sensitive wavelength range of 1100 – 1650 nm, a conversion efficiency of 0.80 A / W, and an FC connector. The angle sensor is an analog output magnetic induction angle sensor. The turntable can be driven by a DC motor to reciprocate, with a rotation range of 90° and a rotation period of 3.5 s. A dual-channel digital oscilloscope can be used to test the output signals of the angle sensor and the photodetector.
[0074] In this embodiment, the light source, the optical fiber coupler, the optical fiber ring, and the photoelectric detector are all rotated along with the turntable, and the output signals of the angle sensor and the photoelectric detector are tested with a dual-channel digital oscilloscope.
[0075] Figure 4It is a flow chart of the data verification method based on the rotating fiber ring interferometer provided by the present invention. The rotating fiber ring interferometer can be used as an experimental device to verify the velocity superposition formula of the special theory of relativity, that is, the Lorentz transformation. After the light emitted by the light source enters from port 1 of the fiber coupler, it is divided into two coherent light beams in a ratio of 50%:50%, and output from port 2 and port 3. Port 2 and port 3 are respectively connected to the two ends of a multi-turn fiber ring formed by a long optical fiber. After the two beams of light entering the fiber ring propagate in the clockwise direction and counterclockwise direction respectively in the fiber ring, they enter the fiber coupler from port 3 and port 2 to meet, and are output from port 4 to the photodetector, and the output light intensity is tested by the photodetector.

Suppose the wavelength of the light emitted by the light source is Assume that the refractive index of the optical fiber is , then the propagation speed of light in a stationary optical fiber is ,in is the speed of light in vacuum. Let the outer radius of the fiber ring be The inner radius is , then its average radius is . Assume that the total length of the optical fiber in the optical fiber ring is When the fiber ring moves at an angular velocity When rotating, the average linear velocity of the optical fiber is According to the Lorentz transformation formula of special relativity, the average speed of light propagating in the optical fiber in the same direction as the rotation direction of the optical fiber ring is The average speed of light propagating in the optical fiber in the direction opposite to the direction of rotation of the optical fiber ring is At the same time, because the interference ring is rotating, the optical path of the light propagating in the same direction as the rotation is longer than the total length of the optical fiber. Longer, the optical path of light propagating in the opposite direction of rotation is longer than the total length of the optical fiber It can be proved that the two beams of light have a total length of The phase difference after the fiber ring is , that is, the phase difference Angular velocity of the fiber ring rotation When the two beams of light are output to the photodetector through the fiber coupler, the output light intensity measured by the photodetector is also related to the angular velocity of the fiber ring rotation. related.
[0077] According to the Galileo velocity transformation formula of Newtonian mechanics, the average speed of light propagating in the optical fiber in the same direction as the rotation direction of the optical fiber ring is , the average speed of light propagating in the optical fiber in the direction opposite to the rotation direction is It can be proved that the two beams of light travel a total length of The phase difference after the fiber ring is zero, that is, the phase difference and the output light intensity tested by the photodetector are related to the angular velocity of the fiber ring rotation. Not relevant.
[0078] Therefore, a rotating fiber ring interferometer is used to test the output light intensity of the photodetector and the angular velocity of the fiber ring rotation. The relationship between them can be used to verify the velocity superposition formula of the special theory of relativity, namely the Lorentz transformation.
[0079] like Figure 4 As shown, the steps of the data verification method include: (1) an oscilloscope or a data acquisition card outputs a turntable angle / angular acceleration, differentiates the turntable angle / integrates the angular acceleration to obtain the turntable angular velocity, the oscilloscope or the data acquisition card outputs a light intensity signal, and the relationship between the light intensity output of the photodetector and the turntable angular velocity is obtained based on the turntable angular velocity and the light intensity signal, and then the turntable angular velocity change range corresponding to one cycle of the light intensity change of the photodetector output is generated.
[0080] The following is an example of using a rotation sensor as an angle sensor and using a dual-channel digital oscilloscope to test the output signals of the angle sensor and the photodetector.
[0081] Figure 5 The figure is a schematic diagram of using a dual-channel digital oscilloscope to test the output signals of an angle sensor and a photodetector provided by the present invention, wherein the solid line represents the output signal of the angle sensor, and the dotted line represents the output signal of the photodetector.
[0082] For the angle value measured by the angle sensor, it is necessary to differentiate the time to obtain the angular velocity. Due to experimental errors and the noise of the angle sensor, the original test data of the angle sensor has errors. If the original data is directly used to differentiate the time to calculate the angular velocity, the angular velocity will also have a large error. In this embodiment, the test value of the angle sensor is first fitted, and then the fitted value is differentiated to solve this problem. The specific steps are as follows: Figure 5 The data of a rotation period of the angle sensor (i.e., from -2.85s to 0.75s) is selected for processing. In this target period, the output of the angle sensor reciprocates from one maximum value to the next maximum value.
[0083] Figure 6 The figure is a schematic diagram comparing the experimental value and the fitting value of the angle sensor output voltage changing with time provided by the present invention. The relationship between the output voltage of the angle sensor and the time t in the target period is subjected to multivariate linear fitting, that is, the relationship between the output voltage of the angle sensor and , Perform linear fitting to obtain the fitting value of the angle sensor. If the fitting value is consistent with the experimental test value, then Figure 6shown.
[0084] Figure 7 Schematic diagram of the relationship between the rotation angular frequency of the turntable and the output voltage of the photodetector over time provided by the present invention. Wherein, ΔΩ=1.25-(-1.2)=2.45rad / s. Figure 7 As shown, the solid line is the relationship between the turntable rotation angular frequency and time obtained after differentiating the angle sensor fitting value, and the dotted line is the relationship between the photodetector output voltage and time.
[0085] Figure 8 Schematic diagram of the relationship between the output of the photoelectric detector provided by the present invention and the angular frequency of the turntable. Figure 8 As shown in the figure, the output voltage of the photodetector is related to the angular frequency of the turntable. When the angular frequency of the turntable changes by 2.45 rad / s, the detection output voltage changes by one cycle, which corresponds to a phase difference change of 2 between the two beams. . From the theoretical formula, we can know that for the parameters of the experimental instrument used, when the turntable angular frequency changes by 2.71 rad / s, the detection output voltage changes by one cycle. The error of the change in experimental angular frequency compared to the change in theoretical angular frequency is -9.6%. According to the Galileo velocity transformation of Newtonian mechanics, the output voltage of the photodetector is independent of the turntable angular frequency, and the rotation of the turntable will not produce a phase difference. Therefore, the Lorentz transformation of the special theory of relativity can be verified.
[0086] In addition, other verifications can be performed based on the rotating fiber ring interferometer. For example, the light source is stationary, and the fiber coupler, fiber ring, and photodetector are rotated with the turntable; or the photodetector is stationary, and the light source, fiber coupler, and fiber ring are rotated with the turntable. For these two cases, since there is relative motion between the light source and the photodetector, the experimental device based on the rotating fiber ring interferometer can also be used to test the influence of the Doppler effect on the experimental phenomenon.
