Description
Technical Field
[0001] This application relates to the field of fiber optic scanning technology, and particularly to a fiber optic scanner. Background Art
[0002] As a high-precision measurement and imaging device, fiber optic scanners are widely used in fields such as industrial inspection, medical imaging, and scientific research experiments. By transmitting light beams through optical fibers and precisely controlling them, fiber optic scanners can achieve high-resolution scanning of target areas and obtain detailed images and data. In these applications, the accuracy, speed, and stability of the scanner are key indicators for evaluating its performance.
[0003] With the development of technology, the performance requirements for fiber optic scanners are getting higher and higher. Users not only expect the scanner to have higher scanning accuracy but also hope it can cover a larger scanning range. However, related fiber optic scanners usually rely on a single type of actuator, showing obvious limitations in applications. Although some actuators have the advantages of high precision and fast response, their displacement range is limited, making it difficult to achieve large-scale scanning. On the contrary, some actuators can provide a larger displacement range but lack in accuracy and response speed. In addition, in complex environments, the seismic resistance and temperature stability of fiber optic scanners are often insufficient, resulting in unstable performance in actual use and affecting the quality of measurement and imaging.
[0004] Related fiber optic scanners have obvious deficiencies in balancing high precision and large-scale scanning as well as environmental adaptability. Summary of the Invention
[0005] In order to alleviate the obvious deficiencies of related fiber optic scanners in balancing high precision and large-scale scanning as well as environmental adaptability, this application provides a fiber optic scanner.
[0006] The fiber optic scanner provided by this application adopts the following technical solutions: A fiber optic scanner, comprising: A housing; A light source, which is arranged at one end inside the housing; An optical fiber, which connects the light source to an actuator; An actuator, which includes a piezoelectric actuator and a linear motor. One end of the linear motor is connected to the optical fiber, and the other end is connected to the piezoelectric actuator. One end of the piezoelectric actuator is connected to the linear motor, and the other end is connected to a fiber optic cantilever; An optical system, which is arranged inside the housing and is oppositely arranged with the fiber optic cantilever, and includes a lens for precise focusing of light beams.
[0007] By adopting the above technical solutions, the combination of the piezoelectric actuator and the linear motor achieves the coordination and unity of high precision and large-range scanning. The piezoelectric actuator is responsible for the precise control of small displacements, providing high resolution and fast response, while the linear motor is responsible for the fast scanning of a large range, ensuring the coverage of a wide scanning area. The structure of the dual actuators compensates for the limitations of a single actuator and significantly improves the overall performance of the system. In addition, the optical fiber connects the light source to the actuator, ensuring that the light beam of the light source can be effectively transmitted to the actuator, improving the stability and reliability of the system. The optical system is arranged inside the housing and is oppositely arranged with the optical fiber cantilever, ensuring the precise positioning of the light beam during the scanning process, thereby improving the resolution and quality of the scanning results.
[0008] Optionally, a connection fixture is provided at the connection between the piezoelectric actuator and the optical fiber cantilever.
[0009] By adopting the above technical solutions, the connection fixture ensures the stable connection between the piezoelectric actuator and the optical fiber cantilever, preventing loosening and displacement caused by mechanical vibration or external interference during the scanning process, thereby improving the overall stability of the system. Secondly, the connection fixture can effectively transmit the small displacements generated by the piezoelectric actuator, ensuring that the advantages of its precise control are fully exerted, and further improving the scanning accuracy and resolution. In addition, the application of the connection fixture simplifies the assembly process of the components, facilitates the maintenance and replacement of the system, and improves the reliability and service life of the optical fiber scanner.
[0010] Optionally, the piezoelectric actuator is provided with an adjustment groove for adjusting the length of the optical fiber cantilever.
[0011] By adopting the above technical solutions, the adjustment groove enables the length of the optical fiber cantilever to be flexibly adjusted according to specific scanning requirements, so as to adapt to different scanning ranges and accuracy requirements. For example, in applications that require a larger scanning range, the length of the optical fiber cantilever can be extended to cover a wider area, while in cases that require high-precision scanning, the optical fiber cantilever can be shortened to ensure more precise beam control. Secondly, by adjusting the length of the optical fiber cantilever, the path of the light beam can be optimized, improving the accuracy of beam focusing. This can not only reduce the attenuation and scattering of the light beam during transmission, improve the resolution and quality of the scanning, but also ensure that the optical fiber scanner can provide consistent high-quality results under different working conditions. In addition, the adjustment groove also provides an effective means to compensate for the deviation of the length of the optical fiber cantilever caused by environmental changes or mechanical wear, ensuring the stability and accuracy of the long-term operation of the system.
[0012] Optionally, the linear motor is connected to the piezoelectric actuator through a guide rail and is used to drive the piezoelectric actuator to move in the scanning plane.
[0013] By adopting the above technical solution, the guide rail ensures smooth and precise relative movement between the linear motor and the piezoelectric actuator. Through this connection method, the linear motor can achieve smooth linear motion over a larger range while maintaining high-precision positioning, thereby ensuring precise control of the fiber cantilever during scanning. Secondly, while the linear motor provides a large range of motion, the piezoelectric actuator is responsible for subtle and precise positioning. The synergy of the two can effectively improve the overall accuracy and response speed of the scanning system. This dual motion mechanism overcomes the limitations of a single drive method, enabling the system to have the ability to scan a large range quickly and make high-precision and detailed adjustments when needed. In addition, the use of guide rails reduces the impact of mechanical friction and vibration on scanning accuracy, ensuring the stability and repeatability of the motion process.
[0014] Optionally, the actuator further includes a coordinated control module for coordinating the movement of the piezoelectric actuator and the linear motor by adjusting a control signal.
[0015] By adopting the above technical solution, the collaborative control module can monitor and adjust the motion state of the piezoelectric actuator and the linear motor in real time, and coordinate the related motion of the two. The application of the collaborative control module enables the system to perform complex motion control and reduces the errors caused by the uncoordinated motion between the actuators. This not only improves the accuracy and consistency of the scanning results, but also enhances the reliability and stability of the system. In addition, the collaborative control module can effectively reduce the vibration and noise generated during the movement by optimizing the adjustment of the control signal, further improving the system performance and user experience.
[0016] Optionally, the collaborative control module includes a signal processing unit and a feedback control unit, which are used to adjust the working parameters of the actuator in real time.
[0017] By adopting the above technical solutions, the signal processing unit can quickly and accurately process the data from the sensor and generate precise control signals to ensure the coordinated movement of the piezoelectric actuator and the linear motor. The feedback control unit provides a closed-loop control mechanism that continuously monitors the working status of the actuator and adjusts the control signal in time to cope with any deviations that may occur during operation. This real-time adjustment mechanism ensures that the system can maintain optimal performance under various working conditions, reduces errors caused by environmental changes or mechanical wear, and significantly improves the stability and reliability of scanning. In addition, the collaborative control module can achieve efficient motion control in complex scanning tasks through the cooperation of the signal processing unit and the feedback control unit. Real-time adjustment of the operating parameters of the actuator enables the system to flexibly respond to different scanning requirements, thereby improving the adaptability and versatility of the system.
[0018] Optionally, a position sensor is provided in the housing, and the position sensor is a laser interferometer, which monitors the position and angle of the optical fiber cantilever in real time and sends the information to the feedback control unit.
[0019] By adopting the above technical solutions, the laser interferometer, as a high-resolution position sensor, can provide extremely high-precision position and angle measurement to ensure the precise positioning of the fiber cantilever during the scanning process. Through this high-precision monitoring method, the resolution and quality of the scan can be effectively improved to meet the needs of high-precision measurement and imaging. Secondly, the real-time monitoring and data transmission functions enable the system to instantly obtain the position information of the fiber cantilever and quickly feed it back to the feedback control unit. Based on these real-time data, the feedback control unit can instantly adjust the operating parameters of the actuator to compensate for any possible displacement error or angle deviation. This closed-loop control mechanism ensures that the system always maintains high precision and high stability during the scanning process, reducing the degradation of scanning quality caused by environmental changes or mechanical errors. In addition, the high sensitivity and high-precision measurement capability of the laser interferometer enhances the system's ability to detect small displacements and subtle angle changes, further improving the overall performance of the fiber scanner.
[0020] Optionally, the optical system includes an adjustable fixing frame, and the fixing frame is fixedly connected to the lens.
[0021] By adopting the above technical solution, the adjustable bracket makes the installation and alignment of the lens more flexible and precise. By adjusting the position and angle of the bracket, the lens can be precisely positioned in the optimal position to ensure accurate focusing and transmission of the light beam. It not only improves the overall performance of the optical system, but also effectively reduces optical distortion and scattering, and improves the quality and resolution of the scanned image. Secondly, the adjustability of the bracket makes the maintenance and calibration process of the optical system easier. When the system needs to be maintained, replaced or recalibrated, by adjusting the bracket, the system can be quickly restored to its optimal state, reducing downtime and improving work efficiency. In addition, the design of the bracket also enhances the adaptability of the system under different working conditions, and can be adjusted according to different application requirements, thereby achieving versatility and flexibility.
[0022] Optionally, a temperature sensor and a radiator are provided in the housing, and when the temperature sensor detects that the temperature exceeds a predetermined value, the radiator is started.
[0023] By adopting the above technical solutions, the temperature sensor monitors the temperature inside the housing in real time to ensure that the system always operates within the optimal temperature range. When the detected temperature exceeds the predetermined safety value, the temperature sensor immediately triggers the radiator to start. By rapidly reducing the internal temperature, it prevents the system from overheating and protects the normal operation and service life of key components. At the same time, it also simplifies the maintenance work of the system. When the system has an automatic temperature control function, there is no need for frequent manual intervention and inspection, reducing the operation complexity and maintenance cost. The combination of the temperature sensor and the radiator not only provides a safety guarantee mechanism but also enables the fiber optic scanner to operate stably in various environments, enhancing the adaptability of the system.
[0024] Optionally, the housing is provided with a shockproof structure, including an internal shock pad and an external shockproof shell.
[0025] By adopting the above technical solutions, the internal shock pad effectively absorbs and alleviates the mechanical vibrations and impacts generated by the external environment, ensuring that the internal precision components work in a stable environment, thereby improving the scanning accuracy and reliability of the system. The external shockproof shell further provides an additional protective layer to resist larger external impacts and vibrations, preventing these external interferences from having an adverse effect on the accuracy and operation stability of the system. The dual shockproof design enables the fiber optic scanner to still operate stably in various complex and harsh environments. Whether it is the high-vibration environment in an industrial site or harsh conditions such as field surveys, the shockproof structure can effectively ensure the normal operation of the equipment and the accuracy of data. This not only expands the application range of the fiber optic scanner but also enhances its adaptability and reliability in high-demand environments.
[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1.

[0031] The following further elaborates on the present application in conjunction with all the attached drawings.
[0032] An embodiment of the present application discloses an optical fiber scanner.
[0033] Referring to Figure 1 , an optical fiber scanner includes a housing 1, a light source 2, an optical fiber 3, an actuator 4, an optical system 6, and multiple sensors.
[0034] First, the housing 1 is the carrier and installation foundation of the optical fiber 3 scanner. The housing 1 is provided with an anti-vibration structure 14, including an internal shock-absorbing pad 141 and an external anti-vibration shell 142. The internal shock-absorbing pad 141 effectively isolates low-frequency and high-frequency vibrations generated by the external environment through the vibration absorption and buffering effects of elastic materials, ensuring that the internal optical and mechanical components can work in a non-interfered state. The external anti-vibration shell 142 provides resistance to external impacts and vibrations through a strong rigid material. When subjected to a large mechanical impact, it can effectively disperse and weaken the impact force, preventing damage to the internal components. The dual anti-vibration not only expands the application range of the optical fiber 3 scanner but also improves its adaptability and reliability in high-demand environments.
[0035] The light source 2 is arranged at one end inside the housing 1 and is connected to the actuator 4 through the optical fiber 3. The optical fiber 3 is made of high-quality optical fiber 3 material, and its two ends are respectively connected to the light source 2 and the actuator 4 to ensure the efficiency and stability of light transmission. The light source 2 transmits light to the actuator 4 through the optical fiber 3, and the actuator 4 is responsible for the motion control of the optical fiber cantilever 5, thereby realizing a high-precision scanning function.
[0036] Refer to Figure 1 and Figure 2, the actuator 4 includes a piezoelectric actuator 41 and a linear motor 42. One end of the linear motor 42 is connected to the optical fiber 3 through a connector, and the other end is connected to the piezoelectric actuator 41 through a precision mechanical connector. One end of the piezoelectric actuator 41 is connected to the linear motor 42 through a fixed connector, and the other end is connected to the optical fiber cantilever 5 through a connection fixture 411. The combination of the piezoelectric actuator 41 and the linear motor 42 achieves the coordination and unity of high precision and large-range scanning.
[0037] Specifically, the piezoelectric actuator 41 is responsible for the precise control of small displacements and can provide high resolution and fast response. When high-precision scanning is required, the piezoelectric actuator 41 can achieve extremely small displacement adjustments to ensure the accuracy of scanning. On the other hand, the linear motor 42 is responsible for large-range and fast scanning to ensure coverage of a wide scanning area. One end of the linear motor 42 is connected to the optical fiber 3 through a connector, and the other end is connected to the piezoelectric actuator 41 to achieve smooth linear motion over a large range while maintaining high-precision positioning.
[0038] One end of the piezoelectric actuator 41 is connected to the linear motor 42 to ensure coordinated movement between the two. The other end is connected to the optical fiber cantilever 5 through a connection fixture 411 to ensure accurate transmission of small displacements. In this way, the light source 2 transmits light to the actuator 4 through the optical fiber 3, and the actuator 4 achieves precise motion control of the optical fiber cantilever 5 by coordinately controlling the piezoelectric actuator 41 and the linear motor 42.
[0039] The structural design of the dual actuator 4 compensates for the limitations of a single actuator 4 and significantly improves the overall performance of the system. The combination of the piezoelectric actuator 41 and the linear motor 42 not only achieves the coordination and unity of high precision and large-range scanning, but also improves the overall accuracy and response speed of the scanning system through their synergistic effect. The piezoelectric actuator 41 is responsible for the precise control of small displacements, providing high resolution and fast response, while the linear motor 42 is responsible for large-range and fast scanning to ensure coverage of a wide scanning area.
[0040] A connection fixture 411 is provided at the connection between the piezoelectric actuator 41 and the optical fiber cantilever 5. Through its high-strength material and locking effect, the connection fixture 411 enables every small displacement generated by the piezoelectric actuator 41 to be accurately transmitted to the optical fiber cantilever 5, ensuring consistent accuracy and stability during high-precision scanning, whether it is for fine adjustments or long-term use. In addition, due to the stable structure of the connection fixture 411, the optical fiber cantilever 5 can remain stable during scanning even when subjected to external vibrations or mechanical shocks, preventing errors from occurring.
[0041] In addition, the piezoelectric actuator 41 is provided with an adjustment groove 412, which enables the length of the optical fiber cantilever 5 to be flexibly adjusted according to specific scanning requirements. At the same time, the adjustment groove 412 can compensate for the length deviation of the optical fiber cantilever 5 caused by environmental changes or mechanical wear, maintain the best performance under various usage environments and requirements, and ensure the consistency and reliability of the scanning results.
[0042] The actuator 4 further includes a cooperative control module 43, which is composed of a signal processing unit 431 and a feedback control unit 432. The module can monitor and adjust the motion states of the piezoelectric actuator 41 and the linear motor 42 in real time to ensure the coordinated and precise control between the two. The signal processing unit 431 quickly and accurately processes the data from the sensors and generates precise control signals to ensure that the piezoelectric actuator 41 and the linear motor 42 always remain synchronized and coordinated during operation.
[0043] Specifically, through advanced data processing algorithms, the signal processing unit 431 can instantly analyze the information fed back by the sensors and generate corresponding control instructions. These instructions ensure that the motion states of the piezoelectric actuator 41 and the linear motor 42 are exactly consistent with the predetermined scanning path, thus avoiding errors and deviations caused by uncoordinated motion. The efficient operation of the signal processing unit 431 enables the system to maintain high-precision and high-stability scanning performance under various complex working conditions.
[0044] The feedback control unit 432 provides a closed-loop control mechanism. By continuously monitoring the working state of the actuator 4, it timely adjusts the control signals to cope with any possible deviations during operation. The feedback control unit 432 real-time monitors the motion data of the piezoelectric actuator 41 and the linear motor 42 and compares these data with the target state. Once a deviation is detected, the feedback control unit 432 immediately adjusts the control signal for real-time correction. This closed-loop control mechanism ensures that the system always maintains the best performance under different environmental conditions and working states.
[0045] To further improve the stability and precision of the system, a high-resolution position sensor 11 is also provided inside the housing 1. The position sensor 11 is a laser interferometer, which can provide extremely high-precision position and angle measurements to ensure the precise positioning of the optical fiber cantilever 5 during scanning.
[0046] As the position sensor 11, the laser interferometer utilizes the principle of laser interference and can achieve precise measurements at the sub-micron level. This high-precision monitoring method significantly improves the scanning resolution and image quality of the optical fiber 3 scanner, meeting the requirements of high-precision measurement and imaging. During scanning, the laser interferometer real-time monitors the position information of the optical fiber cantilever 5 and instantaneously feeds back this information to the feedback control unit 432 of the system through the data transmission function.
[0047] Based on the real-time data provided by the laser interferometer, the feedback control unit 432 can quickly adjust the operating parameters of the actuator 4 to compensate for possible displacement errors or angular deviations. This closed-loop control mechanism ensures that the system always maintains high precision and high stability during the scanning process. Through real-time adjustment and correction, the degradation of the scanning quality caused by environmental changes or mechanical errors is reduced, ensuring the consistency and reliability of the scanning results.
[0048] To ensure that the system operates within the optimal temperature range, a temperature sensor 12 and a radiator 13 are also provided inside the housing 1. These components work together to form an efficient temperature control system, ensuring the stable operation of the fiber optic 3 scanner and the normal operation of key components. The temperature sensor 12 is responsible for monitoring the temperature changes inside the housing 1 in real time. When the temperature sensor 12 detects that the internal temperature exceeds the predetermined safe value, it will immediately send a signal to trigger the radiator 13 to start. The radiator 13 prevents the system from overheating by quickly reducing the internal temperature, thereby protecting the normal operation of key components and extending their service life.
[0049] Reference Figure 3 , the optical system 6 includes an adjustable mount 62 and a lens 61. The mount 62 allows the lens 61 to be precisely positioned at the optimal position by adjusting its position and angle. This adjustment ability ensures the precise focusing and transmission of the light beam, thereby minimizing optical distortion and scattering phenomena. This not only improves the overall performance of the optical system 6 but also significantly enhances the quality and resolution of the scanned image. In addition, the adjustability of the mount 62 greatly simplifies the maintenance and calibration process of the optical system 6. When the system needs to be maintained, replaced, or recalibrated, by adjusting the mount 62, the optimal state of the system can be quickly and accurately restored, thereby reducing downtime and improving work efficiency.
[0050] The implementation principle of a fiber optic scanner in an embodiment of this application is as follows: In an embodiment of this application, through the combined design, precise connection, and coordinated movement of the piezoelectric actuator 41 and the linear motor 42, the coordinated unity of high-precision micro-displacement control and large-range rapid scanning is achieved. The piezoelectric actuator 41 is responsible for the precise control of micro-displacements, providing high resolution and fast response, while the linear motor 42 is responsible for large-range rapid scanning to ensure coverage of a wide scanning area. The collaborative work of the two enables the system to perform excellently under different scanning requirements, thereby significantly improving the scanning accuracy and coverage.
[0051] In the process of achieving high-precision scanning, the fixed connector plays a crucial role. Through the fixed connector, a stable connection between the piezoelectric actuator 41 and the fiber optic cantilever 5 is ensured. The fixed connector made of high-strength material has good anti-vibration performance and stability, and can effectively prevent loosening and displacement caused by mechanical vibration or external interference during scanning. This stable connection not only ensures the accurate transmission of tiny displacements, but also improves the overall stability of the system, thereby further enhancing the scanning accuracy.
[0052] In addition, by connecting the linear motor 42 and the piezoelectric actuator 41 through the high-precision guide rail 421, smooth and precise motion control between the two is ensured. The guide rail 421 is made of wear-resistant material and has excellent durability and accuracy retention ability, enabling the linear motor 42 to achieve smooth linear motion within a larger range while maintaining high-precision positioning. While the linear motor 42 provides large-range motion, the piezoelectric actuator 41 is responsible for fine and precise positioning. The two work together to effectively improve the overall accuracy and response speed of the scanning system. This dual motion mechanism overcomes the limitations of a single driving method, enabling the system to have the ability to perform large-range rapid scanning and, when needed, to make high-precision fine adjustments.
[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
