Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of camera full-automatic image quality testing equipment, in particular to optical fiber light emission angle testing equipment. Background Art
[0002] Optical fiber cables for medical endoscope lighting have an important impact on the use of endoscopes, mainly including the following aspects:
[0003] Lighting effect: The optical cable is responsible for transmitting light from an external light source to the front end of the endoscope, providing sufficient lighting for inspection and surgery. A good optical cable can ensure that the light illuminates the target area evenly and brightly, allowing doctors to clearly observe internal tissues and structures.
[0004] Image quality: The quality of lighting directly affects the quality of images obtained by the endoscope. Sufficient brightness and uniform lighting can improve the contrast and clarity of the image, helping doctors to accurately diagnose diseases and perform surgical operations.
[0005] Field of view: The characteristics of the light output angle determine the field of view that the optical cable can illuminate. A suitable light output angle can ensure that the doctor can fully observe the required area, reduce blind spots, and improve the accuracy of inspection and surgery.
[0006] Operational flexibility: The mechanical properties of the optical cable, such as torsion and bending, affect the operational flexibility of the endoscope during use. If the optical cable can maintain good light transmission performance under various operating conditions, doctors can operate the endoscope more freely and perform delicate examinations and treatments.
[0007] Durability and reliability: The optical cable needs to withstand frequent disinfection, bending, stretching and other operations, so its durability and reliability are crucial. High-quality optical cables can maintain stable performance after multiple uses, reduce the frequency of failures and repairs, and ensure the normal use of endoscopes.
[0008] Safety: The dielectric strength and other properties of the optical cable ensure electrical safety during the use of the endoscope, avoiding dangers such as electric shock to patients and doctors.
[0009] In summary, the performance of optical cables for medical endoscope lighting is directly related to the use effect, safety and reliability of the endoscope, and the performance of the light output angle has a direct impact on the lighting effect, image quality and field of view. Therefore, a device for testing the light output angle of optical fiber is needed. Summary of the invention

[0028] like Figure 2 As shown, a fiber optic light output angle testing device includes a box body 2, a fiber optic interface 1 arranged on one side of the box body 2, an electric rotating mechanism 7 arranged in the box body 2, an electric guide rail 14 arranged on the electric rotating mechanism 7, and an illuminance meter 12 arranged on the electric guide rail 14. The light output angle of the optical fiber 100 to be tested in the fiber optic interface 1 is collected by the illuminance meter 12, the distance of the illuminance meter 12 relative to the fiber optic interface 1 is controlled by the electric guide rail 14, and the inclination angle of the illuminance meter 12 relative to the fiber optic interface 1 is controlled in real time by the electric rotating mechanism 7.
[0029] When testing the light-emitting angle of the optical cable for medical endoscope illumination (i.e., the optical fiber 100 to be tested), the front end of the optical fiber 100 to be tested is plugged into the optical fiber interface 1, so that the light-emitting end of the optical fiber 100 to be tested can be irradiated into the box 2, and then the position of the illuminance meter 12 on the electric guide rail 14 is controlled by the system to keep a certain distance from the optical fiber 100 to be tested, and the illuminance meter 12 is turned on to collect the light-emitting angle of the optical fiber 100 to be tested, and during the collection process, the illuminance meter 12 is rotated relative to the optical fiber 100 to be tested by the electric rotating mechanism 7. 0 is adjusted to different positions, so as to realize the light illumination data collection under different light output angles, so that the medical optical fiber can effectively measure the light output angle data, and the measurement method is simple and convenient, with high repeatability. Since the illuminance meter 12 is located in the closed box 2, it is not affected by external light factors. Different light sources can be tested by replacing the illuminance meter 12. It has high compatibility with different optical fibers 100 to be tested. During the entire operation, precise control is achieved through the electric rotating mechanism 7 and the electric guide rail 14, with a high degree of automation and accurate detection data.
[0030] Further improved, the electric rotating mechanism 7 includes a first rotating table 8 arranged in the box body 2, a rotating arm 10 arranged on the first rotating table 8, and a second rotating table 13 arranged at the front end of the rotating arm 10, the electric guide rail 14 is arranged on the second rotating table 13, and the illuminance meter 12 realizes rotation in the height direction and the horizontal direction through the first rotating table 8 and the second rotating table 13.
[0031] When the position of the illuminometer 12 relative to the optical fiber interface 1 is adjusted by the electric rotating mechanism 7, the first rotating table 8 is fixedly arranged, and the second rotating table 13 is connected to the first rotating table 8 by the rotating arm 10. The rotating arm 10 can be controlled to rotate by the first rotating table 8, thereby realizing the position adjustment of the first rotating table 8, and the electric guide rail 14 can be adjusted by the second rotating table 13, so that the illuminometer 12 can realize the rotation in the height direction and the horizontal direction through the first rotating table 8 and the second rotating table 13, so that the data collection of the illuminometer 12 at different angles is more comprehensive.
[0032] A further improvement is that a bracket 6 is provided between the first rotating table 8 and the box body 2, the first rotating table 8 is arranged on the inner side of the box body 2 through the bracket 6, the second rotating table 13 is provided between the first rotating table 8 and the optical fiber interface 1 through the rotating arm 10, and the second rotating table 13 rotates in a height direction relative to the optical fiber interface 1 through the rotating arm 10; the rotating arm 10 is an L-shaped structure, and the illuminance meter 12 rotates in a horizontal direction relative to the axial direction of the optical fiber interface 1 through the rotating arm 10.
[0033] The first rotating table 8 is fixed to the inner side of the box body 2 away from the optical fiber interface 1 by the bracket 6. Generally, the central axis of the first rotating table 8 is coaxial with the central axis of the optical fiber interface 1, so that when the rotating arm 10 rotates, the illuminance meter 12 rotates with the optical fiber interface 1 as the rotation axis. When testing the light output angles at different angles, the data stability is better. At the same time, it can also make the operation space of the first rotating table 8 and the electric guide rail 14 larger, and the range of collecting the light output angle is wider, and the scope of use is wider. The rotating arm 10 is an L-shaped structure, which can make the axis direction of the second rotating table 13 perpendicular to the axis direction of the first rotating table 8, so that the illuminance meter 12 can rotate in the horizontal direction relative to the axial direction of the optical fiber interface 1 through the second rotating table 13 after rotating in the height direction relative to the optical fiber interface 1 through the first rotating table 8.
[0034] As a further improvement, an electric slide 11 is provided on the electric guide rail 14 , an L-shaped fixing seat 9 is provided on the electric slide 11 , and the illuminometer 12 is provided on the fixing seat 9 .
[0035] When adjusting the distance of the illuminometer 12 relative to the optical fiber interface 1, the electric slide 11 can slide back and forth along the electric guide rail 14, thereby realizing the position adjustment of the L-shaped fixing seat 9. The L-shaped fixing seat 9 can also enable the illuminometer 12 to accurately collect light, thereby making the position adjustment and fixation of the illuminometer 12 simpler and more convenient, and lowering the production cost.
[0036] like Figure 1As shown, a further improvement is that a detachable inspection door 3 is provided on the top of the box body 2, and the interior of the box body 2 is closed by the inspection door 3 to form a lightless cavity.
[0037] The interior of the box 2 is closed by the inspection door 3 to form a light-free cavity, which can make the data more accurate and stable when collecting the optical fiber light output angle, and will not be interfered by the external optical fiber. The inspection door 3 is located at the top of the box 2, which is more convenient for internal inspection and debugging, and has better sealing performance for the side walls, and is not easily directly affected by external factors due to not being tightly covered.
[0038] Among them, one side of the box body 2 is provided with an inwardly recessed depth cylinder 4, the optical fiber interface 1 is arranged on the depth cylinder 4, and the second rotating table 13 is arranged on the outside of the depth cylinder 4 through the rotating arm 10. The second rotating table 13 rotates along the depth cylinder 4 through the first rotating table 8. The depth cylinder 4 can prevent the optical fiber interface 1 from protruding outward, and can also make the adjustment range of the illuminance meter 12 wider, so that the internal space utilization rate is higher.
[0039] As a further improvement, four leveling feet 5 are provided at the bottom of the box body 2, and the leveling feet 5 can provide the box body 2 with better stability when placed.
[0040] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
