Description

Technical Field

[0001] The utility model relates to the technical field of polarization controllers, in particular to an angle fine-tuning multi-ring polarization controller. Background Art

[0002] In the fields of optical communications, fiber optic sensing, laser technology, etc., polarization controllers are mainly used to regulate and control the polarization state of optical signals, and to adjust the polarization direction of light to meet the needs of specific applications.

[0003] Among the existing patent documents, there is a patent with publication number CN 104423076 A, entitled "A Polarization Controller". Although the optical fiber winding axis of this patent can be flipped, the deflection angle of the optical fiber winding axis after flipping cannot be determined. During flipping, only a rough estimate of the flipping angle can be made, resulting in large errors. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide an angle-fine-tuning multi-ring polarization controller. When adjusting the angle of an embedded polarizer element, the polarization controller can display the deflection angle in real time through a display screen. The deflection angle is accurately measured by an angle sensor. When the user flips the embedded polarizer element, the user can observe the angle value displayed on the display screen, which can make the adjustment of the flipping angle of the embedded polarizer element more accurate.

[0005] In order to solve the above technical problems, the technical solution of the utility model is achieved as follows:

[0006] An angle-adjustable multi-ring polarization controller includes a base and an embedded polarizer element. The bottom of the embedded polarizer element is rotatably mounted on the base via an axis, and an optical fiber is embedded in the embedded polarizer element.

[0007] A high-precision angle adjustment indicator component that indicates the flip angle of the embedded polarizer element is fixedly installed at the bottom of the base; the high-precision angle adjustment indicator component includes a main shell, and a driven gear is installed inside the main shell through the rotation of the second shaft. A driving gear arranged concentrically with the shaft is fixedly installed at the bottom of the embedded polarizer element, and the driving gear and the driven gear are engaged with each other for transmission; a hollow cavity is opened inside the driven gear, and an angle sensor is concentrically positioned inside the hollow cavity; a vector sensor, a battery and a display screen are also installed inside the main shell, which are distributed on the front and rear sides of the driven gear. The display screen is located alone in front of the driven gear, and the vector sensor and the battery are both located on the rear side of the driven gear; the angle sensor, the vector sensor, the battery and the display screen are electrically connected.

[0008] Using the above solution, the polarization controller can display the deflection angle in real time on the display screen when adjusting the angle of the embedded polarizer element. The deflection angle is accurately measured by the angle sensor. The user can observe the angle value displayed on the display screen when flipping the embedded polarizer element. It will be more accurate when adjusting the flipping angle of the embedded polarizer element, and its angle error is less than 0.5°.

[0009] As a preferred implementation of the angle fine-tuning multi-ring polarization controller, the diameters of the driving gear and the driven gear are equal.

[0010] With the above solution, in order to achieve proportional transmission, the diameters of the driving gear and the driven gear are designed to be equal. When the embedded polarizer element is rotated a few degrees, the driven gear will also be rotated a few degrees synchronously.

[0011] As a preferred embodiment of the angle fine-tuning multi-ring polarization controller, a cover plate is detachably installed on the inner hollow cavity of the driven gear.

[0012] With the above solution, in order to protect the angle sensor in the hollow cavity, the hollow cavity is sealed by installing a cover plate, thereby achieving protection for the angle sensor.

[0013] As a preferred embodiment of an angle-fine-tuning multi-ring polarization controller, a lead hole 1 is provided through the interior of the second shaft body, through which the line connecting the angle sensor and the vector sensor is guided; a horizontally arranged lead hole 2 is provided within the main housing between the vector sensor and the display screen, through which the line connecting the vector sensor and the display screen is guided; and a partition is provided within the main housing to separate the vector sensor and the battery, and a vertically arranged lead hole 3 is provided through the partition, through which the line connecting the vector sensor and the battery is guided.

[0014] By adopting the above solution, in order to facilitate the layout of the circuits, lead holes 1, 2 and 3 are respectively opened to constrain the circuits connecting the various electronic components, thereby making the overall appearance more beautiful.

[0015] As a preferred embodiment of an angle-fine-tuning multi-ring polarization controller, when the embedded polarizer element is in a vertical state, the deflection angle of the embedded polarizer element is 0°; the deflection angle range of the embedded polarizer element is -90° to 90°.

[0016] The above solution is adopted to distinguish the direction of the deflection angle by adding a vector sensor to distinguish the direction. When the embedded polarizer element is flipped toward the front, the deflection angle transmitted by the angle sensor to the vector sensor is positive; when the embedded polarizer element is flipped toward the rear, the deflection angle transmitted by the angle sensor to the vector sensor is negative.

[0017] As a preferred embodiment of the angle-fine-tuning multi-ring polarization controller, damping is provided on the axial surfaces of the first and second shafts.

[0018] In order to ensure that the embedded polarizer element can be positioned after flipping, damping is set on the axial surface of the first and second shafts to increase the rotational friction between the two, thereby ensuring that the embedded polarizer element can be positioned after flipping.

[0019] After adopting the above technical solution, the beneficial effects of the utility model are:

[0020] 1. When adjusting the angle of the embedded polarizer element, the polarization controller can display the deflection angle in real time on the display screen. The deflection angle is accurately measured by the angle sensor. The user can observe the angle value displayed on the display screen when flipping the embedded polarizer element. It will be more accurate when adjusting the flip angle of the embedded polarizer element, and its angle error is less than 0.5°.

[0021] 2. To achieve proportional transmission, the diameters of the driving gear and the driven gear are designed to be equal. When the embedded polarizer element is rotated a few degrees, the driven gear will also rotate a few degrees synchronously.

[0022] 3. In order to protect the angle sensor in the hollow cavity, the hollow cavity is sealed by installing a cover plate, thereby protecting the angle sensor;

[0023] 4. In order to facilitate the layout of the circuit, lead hole 1, lead hole 2 and lead hole 3 are opened respectively to constrain the circuits connecting various electronic components, thus making the overall appearance more beautiful;

[0024] 5. In order to distinguish the direction of the deflection angle, a vector sensor is added to distinguish the direction. When the embedded polarizer element is flipped toward the front side, the deflection angle transmitted by the angle sensor to the vector sensor is positive; when the embedded polarizer element is flipped toward the rear side, the deflection angle transmitted by the angle sensor to the vector sensor is negative.

[0025] 6. In order to ensure that the embedded polarizer element can be positioned after flipping, damping is set on the axial surface of shaft body 1 and shaft body 2 to increase the rotational friction between the two, so that the embedded polarizer element can be positioned after flipping.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0038] like Figures 1 to 9 As shown, an angle-adjustable multi-ring polarization controller is composed of three groups of polarization controllers. Each group of polarization controllers includes a base 1 and an embedded polarizer element 2. The bottom of the embedded polarizer element 2 is rotatably mounted on the base 1 via an axis 3. An optical fiber 4 is embedded in the embedded polarizer element 2. A high-precision angle adjustment indicator component that indicates the flip angle of the embedded polarizer element 2 is fixedly mounted on the bottom of the base 1. The high-precision angle adjustment indicator component includes a main housing 5. A driven gear 7 is rotatably mounted inside the main housing 5 via an axis 6. The bottom of the embedded polarizer element 2 A driving gear 8 is fixedly mounted concentrically with shaft 1 3 and meshes with a driven gear 7 for transmission. A hollow cavity is defined within the driven gear 7, and an angle sensor 9 is concentrically positioned within the cavity. Also mounted within the main housing 5 are a vector sensor 10, a battery 11, and a display screen 12, located on both the front and rear sides of the driven gear 7. The display screen 12 is located solely on the front side of the driven gear 7, while the vector sensor 10 and battery 11 are both located on the rear side of the driven gear 7. The angle sensor 9, vector sensor 10, battery 11, and display screen 12 are electrically connected. When adjusting the angle of the embedded polarizer element 2, the polarization controller displays the deflection angle in real time on the display screen 12. This deflection angle is accurately measured by the angle sensor 9. When the user flips the embedded polarizer element 2, they can observe the angle value displayed on the display screen 12. This allows for more precise adjustment of the flip angle of the embedded polarizer element 2, with an angle error of less than 0.5°.

[0039] like Figures 4 and 5 As shown, the diameters of the driving gear 8 and the driven gear 7 are equal. In order to achieve proportional transmission, the diameters of the driving gear 8 and the driven gear 7 are designed to be equal. When the embedded polarizer element 2 is turned a few degrees, its driven gear 7 will also turn a few degrees synchronously.

[0040] like Figure 4 、 Figures 6 and 7 As shown, a cover plate 13 is detachably installed on the inner hollow cavity of the driven gear 7. In order to protect the angle sensor 9 in the hollow cavity, the hollow cavity is blocked by installing the cover plate 13, thereby achieving protection for the angle sensor 9.

[0041] like Figures 5 and 6As shown, a lead hole 14 is provided through the interior of the second shaft body 6, through which the wiring connecting the angle sensor 9 and the vector sensor 10 is routed. A horizontal lead hole 2 15 is provided within the main housing 5 between the vector sensor 10 and the display screen 12, through which the wiring connecting the vector sensor 10 and the display screen 12 is routed. A partition is provided within the main housing 5 to separate the vector sensor 10 from the battery 11, and a vertical lead hole 3 16 is provided through this partition to connect the vector sensor 10 and the battery 11. To facilitate wiring, lead hole 14, lead hole 2 15, and lead hole 3 16 are provided separately to constrain the wiring connecting the various electronic components, thereby enhancing the overall aesthetics.

[0042] like Figure 5 、 Figures 8 and 9 As shown, when the embedded polarizer element 2 is in a vertical position, the deflection angle of the embedded polarizer element 2 is 0°; the deflection angle range of the embedded polarizer element 2 is -90° to 90°. To distinguish the direction of the deflection angle, a vector sensor 10 is added to distinguish the direction. When the embedded polarizer element 2 is flipped toward the front, the deflection angle transmitted by the angle sensor 9 to the vector sensor 10 is positive; when the embedded polarizer element 2 is flipped toward the back, the deflection angle transmitted by the angle sensor 9 to the vector sensor 10 is negative.

[0043] Damping is provided on the surfaces of both shaft 1 3 and shaft 2 6. To ensure that the embedded polarizer element 2 can be positioned after flipping, damping is provided on the surfaces of shaft 1 3 and shaft 2 6 to increase the rotational friction between the two, thereby ensuring that the embedded polarizer element 2 can be positioned after flipping.

[0044] The working principle of this utility model:

[0045] In application, when the embedded polarizer element 2 is in a vertical state, the deflection angle of the embedded polarizer element 2 is 0°, that is, the deflection angle displayed on the display screen 12 is 0°. Figure 5 When the embedded polarizer element 2 is flipped toward the front side, the deflection angle transmitted by the angle sensor 9 to the vector sensor 10 is positive, such as 30°, 45°, etc., as shown Figure 8 When the embedded polarizer element 2 is flipped toward the rear side, the deflection angle transmitted by the angle sensor 9 to the vector sensor 10 is negative, such as -30°, -45°, etc., as shown. Figure 9As shown, the user can observe the angle value displayed on the display screen 12 while flipping the embedded polarizer element 2. This allows for more precise adjustment of the flip angle of the embedded polarizer element 2, with an angle error of less than 0.5°. Because damping is provided on the surfaces of the first and second shafts 3 and 6, the embedded polarizer element 2 can be positioned after flipping.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
