[0051] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0052] The following is combined with Figures 1-9 The smooth ring system of the present invention is described.

[0053] like Figure 1As shown, the present invention proposes a first smooth ring system, which may include: an optical signal transmitter 101, a side optical fiber 102, and an optical signal receiver 103;

[0054] The optical signal transmitter 101 is used to obtain target data generated by the target data source, generate an optical signal corresponding to the target data, and output the generated optical signal to the side optical fiber 102 so that the side optical fiber 102 outputs the optical signal outward.

[0055] The optical signal receiver 103 is used to receive the optical signal output by the optical fiber 102.

[0056] It should be noted that the side-lighting fiber 102 is a fully luminous fiber, possessing the characteristic of luminescence throughout. This invention allows the side-lighting fiber 102 to be applied to a smooth ring, utilizing its fully luminous characteristic to avoid the problems of high optical path alignment requirements and poor optical signal transmission reliability in existing technologies, thus effectively enhancing the reliability of optical signal transmission.

[0057] Specifically, the optical signal transmitter 101 can receive data (target data) generated and transmitted by the target data source, generate an optical signal corresponding to the target data, and output the optical signal to the side optical fiber 102, so that the side optical fiber 102 can output the optical signal outward. It is understood that the optical signal in the side optical fiber 102 can propagate radially and also be output from the side. It should be noted that the present invention can add a light-absorbing material to the end face of the side optical fiber 102 to avoid the potential impact of the optical signal emanating from the end face on the optical signal receiver 103, further enhancing the reliability of optical signal transmission.

[0058] Specifically, the optical signal receiver 103 can receive the optical signal output from the side optical fiber 102, perform photoelectric conversion on the optical signal, and obtain the corresponding electrical signal, i.e., the target data.

[0059] In practical applications, the smooth ring system of the present invention may include a rotor component and a stator component. The data transmission direction in the smooth ring system may be data transmission from the rotor component to the stator component or data transmission from the stator component to the rotor component.

[0060] Optionally, in this invention, the optical signal transmitting end 101 and the side optical fiber 102 can be used as rotor components, and the optical signal receiving end 103 can be used as stator components; in this case, the data transmission direction in the smooth ring system can be data transmission from the rotor components to the stator components, and the data transmission rate is relatively high.

[0061] Optionally, the optical signal transmitter 101 and the side optical fiber 102 can be used as stator components, and the optical signal receiver 103 can be used as rotor components; in this case, the data transmission direction in the smooth ring system can be data transmission from the stator components to the rotor components.

[0062] Optionally, in the second smooth ring system proposed in this embodiment of the invention, both the optical signal transmitter 101 and the side optical fiber 102 are rotor components. The optical signal transmitter 101 includes an optical signal generator and a rotating ring body, and the side optical fiber 102 is arranged in a ring on the rotating ring body. When the rotating ring body rotates, both the optical signal generator and the side optical fiber 102 rotate with the rotating ring body. The optical signal receiver 103 is a stator component.

[0063] An optical signal generator is used to obtain target data during the rotation of the rotating ring, generate corresponding optical signals based on the target data, and output the generated optical signals to the side optical fiber 102 that follows the rotation of the rotating ring, so that the side optical fiber 102 that follows the rotation of the rotating ring can output optical signals outward.

[0064] The optical signal receiver 103 is used to receive the optical signal output outward by the side optical fiber 102 that follows the rotation of the rotating ring.

[0065] Optionally, the present invention can place the optical signal receiver 103 in the adjacent area of ​​the side optical fiber 102 in the direction of outputting the optical signal, so as to ensure the receiving efficiency of the optical signal receiver 103 for the optical signal output by the side optical fiber 102.

[0066] Specifically, when the optical signal transmitter 101 and the side-beam optical fiber 102 act as rotor components, and the optical signal receiver 103 acts as a stator component, during the rotation of the device that needs to transmit data through the smooth ring system, the rotating ring in the optical signal transmitter 101 can rotate accordingly. At this time, the optical signal generator and the side-beam optical fiber 102 can rotate together with the rotating ring, while the optical signal receiver 103 can remain in a fixed state. The optical signal generator, while rotating with the ring, receives data generated and transmitted by the target data source, generates a corresponding optical signal, and sends it to the side-beam optical fiber 102. The side-beam optical fiber 102 can then output an optical signal based on its all-over light emission characteristic. Meanwhile, the optical signal receiver 103, in a fixed state, receives the optical signal output from the side-beam optical fiber 102 and, through photoelectric conversion, converts the optical signal into the corresponding target data.

[0067] Optionally, in the second type of smooth ring system described above, a U-shaped channel for arranging the side-light optical fiber 102 in a ring is provided on the outer curved surface of the rotating ring body, and the cross-section of the U-shaped channel is a parabola; wherein, the axis of the side-light optical fiber 102 is arranged at the focus of the parabola.

[0068] Specifically, when a U-shaped channel for arranging the side-light optical fiber 102 in a ring is provided on the outer curved surface of the rotating ring, the present invention can enhance the gain of light in a specific direction by specifically designing and surface-treating the shape of the U-shaped channel. Specifically, the present invention can provide a U-shaped channel with a parabolic interface on the outer curved surface of the rotating ring, improve the reflectivity of the surface through surface treatment, orient the opening of the U-shaped channel towards the stator component, and arrange the side-light optical fiber 102 in a ring on the U-shaped channel, with the axis of the side-light optical fiber 102 arranged at the focal point of the parabola. At this time, the enhancement direction of the light output from the side-light optical fiber 102 is the opening direction of the parabola, i.e., towards the stator component, so that the light signal leaking from the side-light optical fiber 102 is strengthened in the axial direction. This allows the optical signal receiving end 103 to receive more light signals output from the side-light optical fiber 102 on the U-shaped channel. In this case, the U-shaped channel acts as an optical antenna at the transmitting end, enhancing the light-gathering effect.

[0069] Optionally, in the third smooth ring system proposed in this embodiment of the invention, both the optical signal transmitter 101 and the side optical fiber 102 are stator components. The optical signal transmitter 101 includes an optical signal generator and a fixed ring body, and the side optical fiber 102 is arranged in a ring on the fixed ring body. The optical signal receiver 103 is a rotor component. The optical signal receiver 103 includes a rotating ring body and an optical signal receiver. The rotating ring body is arranged inside the fixed ring body, and the optical signal receiver rotates with the rotating ring body.

[0070] An optical signal generator is used to obtain target data, generate corresponding optical signals based on the target data, and output the generated optical signals to the side optical fiber 102 so that the side optical fiber 102 outputs optical signals outward.

[0071] An optical signal receiver is used to receive the optical signal output outward from the side optical fiber 102 during the rotation of the rotating ring.

[0072] Specifically, when the optical signal transmitter 101 and the side-light fiber 102 serve as stator components, and the optical signal receiver 103 serves as rotor components, during the rotation of the device that needs to transmit data through the smooth ring system, the rotating ring in the optical signal receiver 103 can rotate accordingly. At this time, the optical signal receiver can rotate along with the rotating ring. The optical signal transmitter 101, in a fixed state, receives target data sent from the target data source, generates a corresponding optical signal, and sends it to the side-light fiber 102. The side-light fiber 102 can then output an optical signal based on its all-around light emission characteristic. The optical signal receiver, while rotating with the rotating ring, receives the optical signal output from the side-light fiber 102 and converts it into the corresponding target data through photoelectric conversion.

[0073] Optionally, in the fourth smooth ring system proposed in this embodiment of the invention, the optical signal transmitting end 101 includes a target light source driver and a target light generator, and the optical signal receiving end 103 includes a converging lens, a filter and a target light receiver.

[0074] The target light source driver is used to receive target data sent by the target data source, generate a drive signal corresponding to the target data, and send the drive signal to the target light generator.

[0075] The target light generator is used to generate an optical signal with a preset wavelength corresponding to the driving signal, and outputs the generated optical signal to the side optical fiber 102 so that the side optical fiber 102 outputs the optical signal outward.

[0076] A converging lens is used to converge the optical signal output from the side optical fiber 102, and output the converged optical signal.

[0077] A filter is used to receive a converged light signal, allowing light signals of a preset wavelength to pass through while blocking light signals of a different preset wavelength.

[0078] A target optical receiver is used to receive optical signals of a preset wavelength that have passed through a filter and convert the received optical signals into target data.

[0079] like Figure 2 As shown, this invention combines the second and fourth smooth ring systems to propose an example smooth ring system, further illustrating the structure and operation of the smooth ring system of this invention.

[0080] Figure 2 The components located on the rotating side include a laser driver, a laser, a rotating ring, and a side-emitting optical fiber, with the side-emitting optical fiber arranged in a ring within the rotating ring. The components located on the fixed side include a converging lens, a filter, and a light receiver including a photodiode. Figure 2 The data source in the above is the target data source, the laser driver is the target laser driver, the laser is the target light generator, the laser driver and the laser constitute the light signal generator, and the side-emitting optical fiber is the side-emitting optical fiber 102. Figure 2 The optical receiver including a photodiode is the aforementioned target optical receiver. It can be understood that the laser driver, laser, and rotating ring constitute the optical signal transmitter 101, and both the optical signal transmitter 101 and the side-emitting optical fiber serve as rotor components in the smooth ring system; the optical signal receiver 103, consisting of a converging lens, filter, and photodiode, constitutes the optical signal receiver 103, which serves as the stator component in the smooth ring system. The optical signal transmitter 101 is located in the adjacent region in the direction of outward optical signal output from the side-emitting optical fiber 102, such as... Figure 2 The area shown is closer to the rotating ring.

[0081] exist Figure 2 In this process, during the rotation of a device that needs to transmit data through a smooth ring system, the laser driver can receive data (i.e., the target data) output by the device, which serves as the data source (i.e., the target data source mentioned above). Then, based on the received data, the laser driver can drive the laser to output a light signal of a specified wavelength to the side-emitting optical fiber. The side-emitting optical fiber outputs the light signal of the specified wavelength based on its bulk emission characteristic. At this time, a converging lens can be used to converge the light signal output by the side-emitting optical fiber and output the converged light signal to the filter. The filter can pass the light signal of the specified wavelength, block the passage of light of non-specified wavelengths, eliminate the interference of light of non-specified wavelengths and ambient light, and output the light signal of the specified wavelength that passes through to the optical receiver, thereby improving the optical signal-to-noise ratio.

[0082] Optionally, converging lenses can include convex lenses, aspherical lenses, Powell prisms, and Fresnel lenses.

[0083] Optionally, the positions of the filter and the converging lens can be interchanged. That is, the optical signal output from the side-emitting optical fiber can be filtered first using the filter, and then the converging lens can be used to converge the optical signal that has passed through the filter. In this case, the converging lens can directly couple the light in the channel to the photosensitive surface of the photodiode, or indirectly couple the light to the end face of the optical fiber first, and then couple it to the photodiode, so that the optical signal is converged and received.

[0084] Optionally, the present invention may use PIN diodes, avalanche photodiodes, silicon photomultiplier tubes, or photomultiplier tubes to replace photodiodes as photodetectors to receive optical signals.

[0085] like Figure 3 As shown, this invention combines the third and fourth smooth ring systems described above to propose an example smooth ring system, further illustrating the structure and operation of the smooth ring system of this invention.

[0086] Figure 3 The components located on the rotating side include a rotating ring, a converging lens, a filter, and a light receiver including a photodiode. The components located on the fixed side include a fixed ring, a side-emitting optical fiber, a laser, and a laser driver. The rotating ring is located inside the fixed ring, and the fixed ring surrounds the rotating ring. It can be understood that the rotating ring, the converging lens, the filter, and the light receiver including the photodiode constitute the optical signal receiving end 103, which serves as the rotor component in the smooth ring system. The fixed ring, the laser, and the laser driver constitute the optical signal transmitting end 101, and both the optical signal transmitting end 101 and the side-emitting optical fiber serve as the stator components in the smooth ring system.

[0087] The bottom of the fixed ring body can be provided with a channel for the ring arrangement of the side optical fiber 102, and the side optical fiber 102 can be arranged in an inverted ring on the bottom channel of the fixed ring body.

[0088] exist Figure 3 In the process of the device that needs to transmit data through the smooth ring system rotating, the rotating ring can rotate along with it, and the optical signal receiver 103 can rotate with the rotating ring. At this time, the optical signal transmitter 101 can remain in a fixed state, receive the data sent by the device as the data source, generate the corresponding optical signal and send it to the side optical fiber 102. The side optical fiber 102 can output the optical signal outward based on the characteristic of all-body light emission. At this time, the optical signal receiver 103 can receive the optical signal output by the side optical fiber 102 while rotating with the rotating ring, convert the optical signal into an electrical signal, and obtain the data output by the device that needs to transmit data through the smooth ring system.

[0089] Optionally, in the third type of smooth ring system described above, a channel for arranging the side-light optical fiber 102 in a ring is provided on the outer curved surface of the fixed ring body. The bottom of the channel is transparent, and the side-light optical fiber 102 is arranged in a ring in the channel.

[0090] An optical signal receiver is used to receive the optical signal that penetrates the bottom of the channel and is output outward by the side optical fiber 102 during the rotation of the rotating ring.

[0091] Optionally, the aforementioned channel can be a U-shaped channel. This invention can be used in a fixed ring (such as...) Figure 3 A U-shaped channel with a light-transmitting bottom material is provided on the outer curved surface of the fixed ring (as shown). A side-light fiber 102 is arranged in a ring within the U-shaped channel on the outer curved surface of the fixed ring. In this configuration, the optical signal output from the side-light fiber 102 can penetrate through the bottom of the U-shaped channel and be output to the optical signal receiver 103. This eliminates the need for the side-light fiber 102 to be arranged in an inverted manner on the fixed ring, avoiding the risk of equipment damage caused by the fiber 102 becoming entangled on the rotor if it falls off. This enhances equipment safety and reliability, further ensuring data transmission reliability and efficiency.

[0092] Optionally, a ring lens can be used at the bottom of the U-shaped channel of the light-transmitting material. In this case, the present invention can enhance the transmitter gain and reduce channel attenuation.

[0093] Optionally, in any of the above-mentioned smooth ring systems, the optical signal transmitter 101, the side optical fiber 102, and the optical signal receiver 103 can also use spatial division multiplexing technology for data transmission.

[0094] Specifically, when the target data source includes multiple data sources, the target data includes data output from different data sources, or when the target data source includes only one data source that sends different parts of the data in batches, this invention can use spatial division multiplexing technology in the side optical fiber 102 for data transmission, that is, using the same wavelength optical signal to transmit data from different data sources or batches of data from the same data source. For example... Figure 4 The schematic diagram and enlarged view of the stator-side spatial multiplexing shown illustrate that when the optical signal transmitter 101 and the side optical fiber 102 serve as stator components, this invention can be implemented on a fixed ring body (e.g., with a U-shaped channel having a bottom material that is transparent) that is provided with a light-transmitting material as the base material. Figure 3 As shown, the ring-arranged space-division multiplexing fiber, namely the side-light fiber 102 using space-division multiplexing technology, is used to improve data transmission capacity and efficiency and simplify the system.

[0095] Optionally, when the optical signal transmitter 101 and the side optical fiber 102 are used as rotor components, and the side optical fiber 102 is arranged on the rotating ring (e.g.) Figure 2 As shown), this invention allows for the circular arrangement of space-division multiplexing optical fibers on a U-shaped channel within a rotating ring, enabling data transmission using space-division multiplexing technology. Figure 5 The diagram shows the overall view and a partial enlarged view of the rotor-side air separation multiplexing system.

[0096] It should be noted that, in this invention, the optical signal transmitter 101 and the side optical fiber 102 can be disposed on the rotating side, that is, the optical signal transmitter 101 and the side optical fiber 102 can be used as rotor components, and the optical signal receiver 103 can be disposed on the fixed side, that is, the optical signal receiver 103 can be used as stator components, thereby realizing data transmission from rotor components to stator components; Alternatively, the optical signal transmitter 101 and the side optical fiber 102 can be disposed on the fixed side, that is, the optical signal transmitter 101 and the side optical fiber 102 can be used as stator components, and the optical signal receiver 103 can be disposed on the rotating side, that is, the optical signal receiver 103 can be used as rotor components, thereby realizing data transmission from stator components to rotor components, expanding the application scenarios of the smooth ring system, realizing bidirectional communication of the smooth ring system, and improving the practicality of the smooth ring system.

[0097] It should be noted that existing smooth ring systems have high requirements for optical path alignment, which may lead to lower data transmission efficiency. For example... Figure 6The prior art smooth ring system shown can include a rotor and a stator. The rotor includes a rotating ring body, an optical transmitter (TX), and optical fibers. The optical fibers are arranged in a ring on the rotating ring body and have multiple optical signal output ends. The rotor can rotate along with the rotating structure of the device that needs to transmit data through the smooth ring system. The stator can include an optical receiver (RX), which can include multiple optical detection components. Specifically, during the rotation of the device that needs to transmit data through the smooth ring system, the rotor can rotate accordingly. The optical transmitter can receive a 1.25Gb / s data stream from the data source, convert the data stream into corresponding optical signals, and transmit the optical signals to the optical fibers. The optical fibers can output optical signals along each optical signal output end. At this time, the optical receiver can receive the optical signals output from each optical signal output end through each optical detection component, generate electrical signals corresponding to each optical signal, and obtain the data stream transmitted from the data source.

[0098] Among them, Figure 6 In the existing smooth ring system shown, optical signals can only be output from the optical signal output end of the optical fiber along the tangent direction of its circumference. To ensure that the photodetector can effectively receive the optical signal output from the optical signal output end, a large number of optical signal output ends and a large number of photodetectors are required. Furthermore, the alignment angle between the optical signal output end and the photodetector must be strictly set, resulting in high cost and stringent optical path alignment requirements. When the device rotates at a low speed, if the number of optical signal output ends is insufficient, the transmission efficiency of the optical signal to the photodetector will be low, and the photodetector may not be able to continuously obtain optical signals, leading to signal loss.

[0099] Specifically, the smooth ring system of the present invention is provided with an optical signal transmitter 101, a side-beam optical fiber 102, and an optical signal receiver 103. Based on the all-emission characteristic of the side-beam optical fiber 102, the optical signal receiver 103 can continuously receive the optical signal output by the optical signal transmitter 101 through the side-beam optical fiber 102, avoiding the problem of missing optical signal transmission, reducing the optical path alignment requirements, effectively ensuring the optical signal transmission efficiency, effectively reducing the setting of optical detection components, and reducing component costs.

[0100] The smooth ring system proposed in this invention may include an optical signal transmitter 101, a side-beam optical fiber 102, and an optical signal receiver 103. The optical signal transmitter 101 is used to obtain target data generated by a target data source, generate an optical signal corresponding to the target data, and output the generated optical signal to the side-beam optical fiber 102, so that the side-beam optical fiber 102 outputs an optical signal outward. The optical signal receiver 103 is used to receive the optical signal output outward from the side-beam optical fiber 102. The smooth ring system of this invention, with its optical signal transmitter 101, side-beam optical fiber 102, and optical signal receiver 103, leverages the all-emitting characteristic of the side-beam optical fiber 102 to continuously receive the optical signal output from the optical signal transmitter 101 through the side-beam optical fiber 102, avoiding the problem of missing optical signal transmission, reducing optical path alignment requirements, effectively ensuring optical signal transmission efficiency, effectively reducing the need for optical detection components, and lowering component costs.

[0101] Based on the fourth type of smooth ring system described above, this embodiment of the invention proposes a fifth type of smooth ring system. In the fifth type of smooth ring system, the target data source includes multiple data sources, the target light source driver includes multiple light source drivers, the target light generator includes multiple light generators, and the optical signal transmitter 101 also includes a multiplexer and a connecting optical fiber; the input end of each light generator is connected to each light source driver, the output end of each light generator is connected to the input end of the multiplexer, and the output end of the multiplexer is connected to the side light optical fiber 102 through the connecting optical fiber;

[0102] Each light source driver is used to receive data sent by a data source, generate a corresponding driving signal based on the received data, and send the generated driving signal to a connected light generator;

[0103] Each optical generator is used to generate an optical signal with a preset wavelength that corresponds to the received driving signal, and then sends the generated optical signal to the multiplexer.

[0104] The multiplexer is used to receive the optical signals output by each optical generator, couple the optical signals into a coupled optical signal through the connecting optical fiber, and output it to the side optical fiber 102, so that the side optical fiber 102 outputs the coupled optical signal outward.

[0105] It should be noted that when the target data source includes multiple independent data sources, the present invention can apply wavelength division multiplexing technology while setting the side optical fiber 102 to transmit the data output from each data source in the smooth ring system, thereby further improving the data transmission capacity and data transmission efficiency.

[0106] Specifically, this invention can configure multiple light source drivers for receiving data from various data sources, and configure light generators connected to each light source driver. Each light source driver can receive data from one data source and drive the connected light generator to output a light signal of a specified wavelength based on the received data. For example, when the target data source includes a first data source and a second data source, this invention can configure a first light source driver and a second light source driver in the target light source driver, and configure a first light generator connected to the first light source driver and a second light generator connected to the second light source driver in the target light generator. In this case, the first light source driver can be used to receive data from the first data source and drive the first light generator to output a light signal of a first wavelength, and the second light source driver can be used to receive data from the second data source and drive the second light generator to output a light signal of a second wavelength.

[0107] Specifically, the multiplexer can receive the optical signals generated and output by each optical fiber, and couple these signals to the same optical fiber 102 via connecting optical fibers, so that the optical fiber 102 outputs optical signals of different wavelengths. For example... Figure 7 As shown, the target data source may include data source 1, data source 2... data source n, the target light source driver may include n laser drivers, and the target light generator may include n lasers. Each laser driver can receive data sent by each data source and drive the corresponding laser to generate optical signals with wavelengths of λ1, λ2... λn. Then, the multiplexer can couple the optical signals of each wavelength to the ring optical fiber, i.e., the ring-arranged side optical fiber 102, through the connecting optical fiber, and output the optical signal to the optical signal receiving end 103 from the side optical fiber 102.

[0108] Optionally, the data sources in the target data source can also originate from the same high-speed data source. In this case, the present invention can use a switching device to decompose the high-speed data source into low-speed data streams, so that different data streams are transmitted on different wavelengths, and then multiplexed into high-speed data streams at the optical signal receiving end 103 using the switching device.

[0109] Optionally, the target optical receiver includes multiple optical receivers, and the optical signal receiving end 103 further includes: a receiving optical fiber and a demultiplexer; the input end of the demultiplexer is connected to the receiving optical fiber, and the output end of the demultiplexer is connected to each optical receiver through optical fibers respectively.

[0110] The demultiplexer is used to obtain the coupled optical signal output from the side optical fiber 102 through the converging lens, filter and receiving optical fiber, decompose the coupled optical signal into corresponding optical signals, and send each optical signal to the respective optical receiver through the optical fiber.

[0111] Each optical receiver is used to convert the received optical signal into corresponding data.

[0112] Specifically, this invention can decompose and receive optical signals of multiple wavelengths output from the side-light fiber 102 by setting up a demultiplexer and multiple optical receivers. For example... Figure 8 As shown, the present invention adopts an indirect coupling method, which allows the demultiplexer to obtain the coupled optical signal sequentially through the filter, the converging lens and the receiving optical fiber (i.e. the aforementioned receiving optical fiber), decompose the optical signal into optical signals of different wavelengths, and send the optical signals of different wavelengths to each optical receiver through the optical fiber.

[0113] It is understood that, while setting up the side optical fiber 102 and applying wavelength division multiplexing technology, the present invention can also apply space division multiplexing technology in communication in each direction. That is, wavelength division multiplexing technology and / or space division multiplexing technology are used to transmit data at the optical signal transmitter 101, the side optical fiber 102 and the optical signal receiver 103, thereby further improving the data transmission capacity and data transmission efficiency.

[0114] The smooth ring control system proposed in this invention can further improve data transmission capacity and data transmission efficiency by applying wavelength division multiplexing technology while setting the side optical fiber 102.

[0115] Based on the above-described smooth ring system, this invention proposes a sixth smooth ring system, which can be applied to data transmission scenarios in medical testing devices during operation, such as data transmission scenarios in CT scanner systems during operation. Figure 9 As shown, the CT scanner system may include a CT scanner and a computer system control console. The CT scanner may include equipment such as a scanning bed and a scanning gantry. The smooth ring communication system, also known as a smooth ring system, may include an optical signal transmitter 101, a side-beam optical fiber 102, and an optical signal receiver 103. The optical signal transmitter 101 and the side-beam optical fiber 102 may be rotor components, and the optical signal receiver 103 may be a stator component. Specifically, the optical signal receiver 103 may include devices such as a beam expander lens, a converging lens, a filter, and an optical receiver, which includes a photodiode. In this smooth ring system, the data transmission direction is from the rotor component to the stator component.

[0116] Specifically, the CT scanner can serve as the target data source, scanning the target object during movement to obtain scan data. This scan data is then sent to the optical signal transmitter 101 in the smooth ring system. The optical signal transmitter 101 generates a corresponding optical signal based on the scan data and outputs it to the side optical fiber 102. The side optical fiber 102 outputs the optical signal based on its body-emitting characteristics. The optical signal receiver 103 receives this optical signal and performs photoelectric conversion to obtain the corresponding scan data. Specifically, the optical signal can be transmitted through an optical path in the smooth ring system. The photodiode in the optical signal receiver 103 receives the optical signal and converts it into an electrical signal, which is then sent to the computer system control panel. After data processing, the computer system can reconstruct an image corresponding to the scan data.

[0117] It should be noted that the smooth ring system of the present invention can be applied to data transmission scenarios of medical testing devices, ensuring the efficiency of medical testing data transmission.

[0118] The smooth ring system proposed in this invention can effectively ensure the efficiency of medical testing data transmission.
