[0042] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.
[0043] It should be understood that when used in this specification and the appended claims, the term "comprising" indicates the presence of described features, integers, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.
[0044] It should also be understood that the terms used in this application specification are only for the purpose of describing specific embodiments and are not intended to limit the application. As used in this application specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.
[0045] In addition, in the description of the present application, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0046] Endoscopic systems generally include light source equipment and endoscopes. Figure 1 As shown, the endoscope includes an insertion portion 12, an operating portion 13 and a connecting portion 14, wherein the insertion portion includes a head end portion 11. The optical fiber assembly includes a plurality of optical fibers, and the optical fiber assembly runs through the entire endoscope, that is, the optical fiber assembly starts from the connecting portion 14, passes through the operating portion 13 and the insertion portion 12 in sequence, and ends at the head end portion 11 of the insertion portion 12. The connecting portion 14 is connected to a light source device, and the light emitted by the light source device is transmitted through the optical fiber and emitted from the head end portion. The head end portion 11 is placed in the observation area to observe the observation area.
[0047] The operating part 13 is provided with a direction adjustment button (for example, a knob) for controlling the insertion part 12 to bend in four different directions, namely, up, down, left, and right, so that different positions of the observation area can be observed. The optical fiber is generally a vulnerable part and is easily broken during the bending process of the insertion part 12, which in turn causes the light intensity of the light emitted by the light source to be weakened after being transmitted through the optical fiber, affecting the use.
[0048] To this end, the present application provides a fiber optic detection method, which obtains the light output information of the light output area at the end of the endoscope head, divides the light output area into multiple sub-areas, and the deformation morphology of the optical fiber corresponding to each sub-area is consistent. The light intensity of each sub-area is determined according to the light output information, and the light intensity difference information between each sub-area is compared. Since the loss of optical fibers with consistent deformation is relatively close, the sub-area where the optical fiber is concentratedly damaged in the endoscope can be determined according to the light intensity difference information between each sub-area, so that the technician can replace or optimize the optical fiber of the endoscope in response to the concentrated damage of the optical fiber, thereby increasing the service life of the endoscope and reducing maintenance costs.
[0049] The optical fiber detection method provided in the present application is exemplarily described below.
[0050] The optical fiber detection method provided in the present application is applied to an optical fiber detection system. For example, it can be applied to Figure 2 The fiber optic detection system shown in the reference Figure 2, the fiber optic detection system provided in one embodiment of the present application includes a light source 21, a lens group 22, an endoscope 23, a detector 24 and a data processor 25. Among them, the light emitted by the light source 21 enters the incident end (such as the connecting part) of the endoscope 23 after being focused by the lens group 22, and is emitted from the output end (such as the head end) after being transmitted by the optical fiber component in the endoscope 23. The detector 24 detects the output end, obtains the light output information, and sends the light output information to the data processor 25. The data processor 25 determines the damage of the optical fiber component by analyzing the light output information. It should be understood that, Figure 2 This is only an exemplary optical fiber detection system. In actual applications, it can be constructed according to the needs. Figure 2 The same or different optical fiber detection systems. For example, in some optional embodiments, the optical fiber detection system may not include the lens 22, or the lens 22 may be a collimating lens or other types of lenses. Figure 2 The description will continue with the example of the optical fiber detection system shown.
[0051] The optical fiber detection method provided in the present application is executed in an electronic device, and the electronic device may be a data processor 25, or may include more contents other than the data processor 25, and the present application does not limit this. For example, in some optional embodiments, the electronic device may be a device including a detector 24 and a data processor 25, or a device including a light source 21, a lens group 22, a detector 24, and a data processor 25.
[0052] The optical fiber detection method provided in the embodiment of the present application is introduced below in combination with the above-mentioned optical fiber detection system.
[0053] like Figure 3 As shown, the optical fiber detection provided by an embodiment of the present application includes:
[0054] S301: Acquire first light output information of a light output area corresponding to an endoscope, wherein the light output area is an area illuminated by light after being transmitted through an optical fiber component in the endoscope, wherein the optical fiber component includes a plurality of optical fibers.
[0055] Specifically, Figure 4 As shown, the optical fiber assembly includes a plurality of optical fibers 41 arranged in parallel, and the end face of the optical fiber assembly can be circular, or can be other regular or irregular shapes.
[0056] In one embodiment, the light emitted by the light source enters from the connection part of the endoscope, is transmitted through the optical fiber assembly, and then is emitted from the head end of the endoscope. The area illuminated by the emitted light is the light-emitting area, and the light-emitting area corresponds to the end surface of the optical fiber assembly. For example, when the light is emitted from the head end and illuminates an illuminated surface, the light-emitting area can be the spot area formed by the light emitted from the head end on the illuminated surface.
[0057] In another embodiment, the light emitted by the light source may also enter from the head end of the endoscope, be transmitted through the optical fiber assembly, and then be emitted from the connecting portion of the endoscope, and the area illuminated by the emitted light is the light emitting area.
[0058] The first light output information may include any one or more of the information such as luminous flux, light intensity, pixel information of the light spot corresponding to the light output area, etc., which can be determined according to actual needs.
[0059] S102: Determine the light intensity of each sub-area of the light exit area according to the first light exit information, wherein the deformation morphology of the optical fiber in the optical fiber assembly corresponding to each sub-area is consistent.
[0060] Specifically, the light exiting area is divided into a plurality of sub-areas so that the deformation forms of the optical fibers in the optical fiber assemblies corresponding to the sub-areas are consistent, that is, each sub-area is an area illuminated by the optical fibers having consistent deformation forms.
[0061] Among them, optical fiber deformation is caused by optical fiber bending. During the bending process, part of the optical fiber is squeezed and part of the optical fiber is stretched, resulting in inconsistent deformation forms of the optical fibers in the optical fiber assembly. For example, when using an endoscope, the user can bend the optical fiber assembly to the upper, lower, left, right, etc., resulting in multiple deformation forms of the optical fibers in the optical fiber assembly. In the embodiment of the present application, the deformation forms at least include stretching and squeezing.
[0062] It can be understood that in practical applications, for each sub-region, there is a certain tolerance for the deformation morphology of each optical fiber corresponding to it, and the deformation morphology of the optical fiber corresponding to each sub-region can be roughly consistent. For example, when the proportion of optical fibers with consistent deformation morphology in a region reaches a preset ratio threshold, it can be determined that the deformation morphology of the optical fibers in this region is consistent. Among them, the ratio threshold can be set according to actual needs, such as in some embodiments, it can be 90%.
[0063] In one embodiment, the division of each sub-area of the light output area is determined according to the rotation direction of the optical fiber assembly during the use of the endoscope. For example, according to the squeezing or stretching of each optical fiber when the optical fiber assembly rotates in different directions during the use of the endoscope, the area corresponding to the optical fiber with the same squeezing tendency and the same stretching tendency is regarded as the same sub-area. By determining the division of the sub-area according to the rotation direction of the optical fiber assembly during the use of the endoscope, the optical fiber with the same deformation state in the optical fiber deformation form corresponding to each rotation direction can be located in one sub-area, and the optical fiber damage in each sub-area corresponds to the user operation, so that the optical fiber damage caused by each bending direction can be analyzed.
[0064] In one embodiment, the rotation direction of the endoscope includes four directions: up, down, left, and right. Correspondingly, the light emitting area includes four areas.
[0065] For example, Figure 5 As shown in (A) in the figure, the light-emitting area is evenly divided into 4 sub-areas. After the up-down rotation direction and the left-right rotation direction of the endoscope are obtained, the position of the dividing line can be determined according to the angle between the dividing line of the 4 sub-areas and the up-down rotation direction and the left-right rotation direction, and the light-emitting area is divided into 4 sub-areas. The angle between the dividing line of the 4 sub-areas and the up-down rotation direction and the left-right rotation direction can be preset. For example, as an optional embodiment of the present application, refer to Figure 5 (B) is a schematic diagram of the four rotation directions of up, down, left, and right and the division of quadrants. In the embodiment of the present application, in order to divide the optical fibers with the same deformation state corresponding to the four directions into the same quadrant as much as possible, the four quadrant dividing lines are determined by rotating 45 degrees (i.e., the angle is 45 degrees) with the four rotation directions, thereby obtaining four quadrants (each quadrant is a sub-area).
[0066] It can be understood that in other embodiments, the number of sub-regions obtained by dividing the light region may be greater than 4. In this case, optical fibers with the same deformation state corresponding to the same rotation direction may be divided into a plurality of corresponding sub-regions.
[0067] The first light emitting information includes the light intensity at each position of the light emitting area. The electronic device can obtain the light intensity of each sub-area by statistics according to the position of each sub-area.
[0068] In one embodiment, after obtaining the first light output information, the electronic device first determines the light transmission efficiency of the optical fiber assembly according to the first light output information and the second light output information of the light source emitting the light. The second light output information may include information such as luminous flux and brightness. The light transmission efficiency may be the ratio of the luminous flux of the first light output information to the luminous flux in the second light output information, or the ratio of the brightness in the first light output information to the brightness in the second light output information.
[0069] After determining the light transmission efficiency of the optical fiber assembly, the electronic device preliminarily determines whether the optical fiber assembly is excessively damaged. An excessively damaged optical fiber assembly refers to an optical fiber assembly in which the number of broken optical fibers reaches a certain proportion. Specifically, when the light transmission efficiency is greater than a first preset value (for example, 50%), it is preliminarily determined that the optical fiber assembly is not excessively damaged, and then the light intensity of each sub-area of the light output area is further determined based on the first light output information. It can be understood that when the light transmission efficiency is less than or equal to the first preset value, it is determined that the optical fiber assembly is excessively damaged, and the electronic device may not calculate the light intensity of each sub-area. Among them, the specific size of the first preset value can be determined according to the actual product situation, and is not overly limited here. For example, in some optional embodiments, if the endoscope is tested during the assembly process, different first preset values can be set according to the actual situation of different assembly links, so as to achieve an effective evaluation of whether the actual loss degree of each assembly link is reasonable.
[0070] In one embodiment, the electronic device collects the light transmission efficiency of the optical fiber assembly when the brightness of the light source is different. Afterwards, when it is determined that each light transmission efficiency is greater than a first preset value, or the average value of the light transmission efficiency is greater than the first preset value, the electronic device preliminarily determines that the optical fiber assembly is not damaged or has not reached the damage threshold, and further determines the light intensity of each sub-area of the light output area according to the first light output information.
[0071] S303: Determine the damage condition of the optical fiber in the optical fiber assembly according to the light intensity difference information between the sub-regions, where the damage condition of the optical fiber includes the sub-region where the optical fiber is concentratedly damaged.
[0072] Specifically, the light intensity difference information between each sub-region may include the light intensity difference between two adjacent sub-regions, or may include the light intensity difference between two sub-regions relative to the center point of the light exit region. The damage condition of the optical fiber may include the sub-region where the optical fiber is concentratedly damaged, or may include information on whether there is concentrated damaged optical fiber in each sub-region, or may include the degree of damage to the optical fiber in each sub-region, etc.
[0073] For example, Figure 5As shown in (C), the light intensity of each sub-region is different, and the light intensity of sub-region 2, sub-region 3, sub-region 1, and sub-region 4 decreases in sequence. If the light intensity difference between sub-region 4 and sub-region 2, sub-region 3, and sub-region 1 is greater than the second preset value, sub-region 4 is determined to be the region where the optical fiber is concentratedly damaged. Alternatively, if the light intensity difference between sub-region 4 and sub-region 2, sub-region 3, and sub-region 1 is greater than the second preset value, sub-region 1 and sub-region 4 whose light intensity is less than the first threshold are regarded as sub-regions where the optical fiber is concentratedly damaged. Among them, the second preset value can be the difference obtained by subtracting two light intensities, or it can be the ratio of the difference obtained by subtracting two light intensities to one of the light intensities (for example, 25%). The specific size of the second preset value can be determined according to factors such as the brightness of the light source and the current assembly link. In the above embodiment, according to the deformation form of the optical fiber in the optical fiber assembly, the light output area corresponding to the optical fiber assembly is divided into multiple sub-regions, so that the deformation form of the optical fiber corresponding to each sub-region is consistent. By determining the light intensity difference information between each sub-area to determine the damage condition of the optical fiber in the optical fiber assembly, the concentrated damage condition of the optical fiber can be determined, so that the optical fiber assembly can be optimized according to the concentrated damage condition.
[0074] For example, when the optical fiber in one area of the optical fiber assembly is broken, it will affect the use of the endoscope, and the optical fiber needs to be replaced, resulting in a high replacement cost. The optical fiber assembly is made into an assembleable structure according to the deformation form of the optical fiber assembly. For example, the optical fiber assembly includes 4 groups of optical fiber assemblies, and the deformation form of the optical fiber in each optical fiber assembly is consistent. After the optical fibers in the optical fiber assembly are inspected, the optical fiber assembly where the optical fiber is damaged can be determined, so that only one of the optical fiber assemblies (i.e., a part of the optical fiber) can be replaced to continue using the endoscope, thereby increasing the service life of the endoscope and reducing the replacement cost.
[0075] For another example, by testing the optical fiber and determining the damage status of the optical fiber in each sub-area, the operation direction (or operation habit) of the user corresponding to the sub-area where concentrated optical fiber damage occurs can be obtained, so that the optical fiber in this sub-area can be optimized in the subsequent production process. For example, the optical fiber corresponding to the sub-area can be reinforced through further processing.
[0076] In one embodiment, after determining the light intensity of each sub-region, the electronic device determines the local light intensity difference within each sub-region. The local light intensity difference within each sub-region includes the light intensity difference between each local region within each sub-region. According to the local light intensity difference within the sub-region, it can be determined whether there is local concentrated damage to the optical fiber within the sub-region. For each sub-region, the sub-region can be evenly divided into at least two local regions, and the light intensity difference between each local region is determined. For example, Figure 6As shown in (A) in FIG. 1 , the sub-region 1 is evenly divided into two local regions A and B. For each sub-region, the positions in the sub-region where the brightness is lower than a preset brightness can be first determined, and the connected region composed of the positions where the brightness is lower than the preset value is taken as the dark spot region, and the light intensity difference between the dark spot region and the non-dark spot region is determined. For example, Figure 6 As shown in (B) in FIG. 1 , the sub-region 1 is divided into a dark spot region C and a non-dark spot region D.
[0077] After determining the difference in local light intensity within each sub-region, the electronic device determines the damage of the optical fiber in the optical fiber assembly based on the light intensity difference information between the sub-regions and the local light intensity difference within each sub-region. Based on the local light intensity difference within each sub-region, it can be determined whether the optical fiber corresponding to the sub-region has inconsistent local brightness, and then determine whether there is concentrated damage to the optical fiber within the sub-region. Therefore, combined with the difference information between and within the sub-regions, the concentrated damage and dispersed damage of the optical fiber assembly can be determined more accurately, so that technicians can optimize the optical fiber assembly more specifically according to the damage situation.
[0078] In one embodiment, after determining the light intensity difference between the sub-areas, the electronic device determines whether the light intensity difference is less than a second preset value.
[0079] If the light intensity difference is less than the second preset value, it means that the light intensity difference between the sub-areas is small, and then further determine whether the local light intensity difference within each sub-area is less than the third preset value. If the local light intensity difference within each sub-area is less than the third preset value, it means that the local light intensity difference within each sub-area is small, and it is determined that there is no sub-area in the optical fiber assembly where the optical fiber is concentratedly damaged. Among them, the third preset value can be the difference obtained by subtracting two light intensities, or it can be the ratio of the difference obtained by subtracting two light intensities to one of the light intensities. The specific size of the third preset value can be determined based on factors such as the brightness of the light source, the light intensity of the current sub-area, and the current assembly link.
[0080] When the light intensity difference between each sub-region is less than the second preset value, for each sub-region, if there is a sub-region where the local light intensity difference is greater than or equal to the third preset value, it means that there is a sub-region with a large local light intensity difference, and the sub-region where the local light intensity difference is greater than or equal to the third preset value is taken as the sub-region where the optical fiber is concentratedly damaged. For the sub-region where the optical fiber is concentratedly damaged, a local region with a smaller light intensity can also be determined based on the light intensity of each local region within the sub-region. Since the reason for the smaller light intensity in the local region is the breakage of the optical fiber in the corresponding region, the local region with a smaller light intensity is the local region where the optical fiber is concentratedly damaged. After determining that there is a sub-region where the optical fiber is concentratedly damaged, the electronic device can also output the local region where the optical fiber is concentratedly damaged.
[0081] After the electronic device determines the light intensity difference between each sub-region, if it is determined that there is a sub-region whose light intensity difference with other sub-regions is greater than or equal to the second preset value, it means that the degree of optical fiber damage in each sub-region is inconsistent. The smaller the light intensity, the more serious the optical fiber damage, so the sub-region with light intensity less than the first threshold is regarded as the sub-region where the optical fiber is concentratedly damaged. Among them, the first threshold can be set according to actual needs. For example, when the light intensity is less than the first threshold, the clarity of the object observed through the endoscope does not meet the use requirements. After determining that there is a sub-region where the optical fiber is concentratedly damaged, the electronic device can also output the sub-region where the optical fiber is concentratedly damaged.
[0082] In another embodiment, after determining that there is a sub-region whose light intensity difference with other sub-regions is greater than or equal to the second preset value, the local light intensity difference inside the sub-region may be determined, so that the sub-region may be further analyzed to determine the optical fiber damage inside the sub-region. For example, when the light intensity difference between a sub-region and other sub-regions is greater than or equal to the second preset value, if it is determined that the local light intensity difference inside the sub-region is less than the third preset value, it indicates that there is a dispersed optical fiber damage in the sub-region, and if it is determined that the local light intensity difference inside the sub-region is greater than or equal to the third preset value, it indicates that there is a concentrated optical fiber damage in the sub-region.
[0083] In other embodiments, detecting the light transmission efficiency of the optical fiber assembly, determining the light intensity difference between the sub-regions, and determining the local light intensity difference within each sub-region can be performed simultaneously. After obtaining the above information, the electronic device can comprehensively determine the damage of the optical fiber in the optical fiber assembly based on the above information.
[0084] In the above embodiment, by dividing the light output area into multiple sub-areas and comparing the light intensity differences between the sub-areas and the light intensity differences within each sub-area, the optical fiber damage conditions in each sub-area and the optical fiber damage conditions within each sub-area can be determined, thereby more accurately locating the area where the optical fiber with concentrated damage occurs, thereby facilitating the technicians to subsequently optimize the design of the optical fiber assembly.
[0085] In one embodiment, during the assembly of the endoscope, after each assembly link is completed, the above-mentioned optical fiber detection method is used to detect the optical fiber in the optical fiber assembly. That is, after each assembly link is completed, the light flux of the optical fiber assembly is detected, the light intensity difference between the sub-areas is determined, and the local light intensity difference within the sub-areas is determined. For each assembly link, after the completion of the optical fiber detection, it is determined whether there is an area where the optical fiber is concentratedly damaged, and then the abnormal assembly link is determined according to the damage of the optical fiber.
[0086] The assembly process of the endoscope includes bonding the optical fiber barrel, assembling to the head end seat, inserting the bundle into the tube, etc. During the assembly process of the endoscope, each assembly process will stretch or squeeze the optical fiber to a certain extent, and the degree of squeezing and stretching of the optical fiber in each assembly process is different, and each assembly process may cause damage to the optical fiber. In one embodiment, the first preset value, the second preset value, and the third preset value corresponding to each assembly process are different, so that different assembly processes can be analyzed more accurately, avoiding invalid analysis caused by fixed first preset values, second preset values, and third preset values. For example, if the fixed first preset value, second preset value, and third preset value are set, the threshold is too high for some assembly processes, and the measurement results cannot meet the requirements, resulting in meaningless measurement results. For some assembly processes, the threshold is too low, resulting in unreliable and meaningless analysis results.
[0087] In one embodiment, during the assembly of the endoscope, the electronic device obtains the current assembly link, determines any one or more of the first preset value, the second preset value, and the third preset value according to the current assembly link, and then uses the above-mentioned optical fiber detection method to detect the optical fiber in the optical fiber assembly. For example, first determine whether the light transmission efficiency of the optical fiber assembly is greater than the first preset value. In the case where the light transmission efficiency is greater than the first preset value, determine whether the light intensity difference between each sub-area is less than the second preset value. In the case where the light intensity difference between each sub-area is less than the second preset value, determine whether the local light intensity difference within each sub-area is less than the third preset value, and then determine the damage of the optical fiber in the optical fiber assembly, and then determine whether the current assembly link is abnormal. Compared with detecting the optical fiber after the assembly is completed, the cause of the abnormality can be determined in time to avoid invalid assembly.
[0088] The first preset value, the second preset value and the third preset value corresponding to each assembly link can be determined according to the degree of compression and stretching of the optical fiber in each assembly link or according to the assembly order of each assembly link. For example, the first preset value corresponding to the bonding optical fiber lens barrel link is greater than the first preset value corresponding to the insertion tube bundle threading link.
[0089] In one embodiment, the electronic device can also obtain first light output information from the light output area of the endoscope at set time intervals during the use of the endoscope, analyze the light intensity differences between and within the sub-areas based on the first light output information and the sub-area division, determine the optical fiber damage, and then count the optical fiber damage trends of each sub-area, thereby facilitating technicians to optimize the optical fiber components based on the optical fiber damage trends.
[0090] In one embodiment, the specific process of the optical fiber detection method is as follows.
[0091] The electronic device obtains the first light output information and the current assembly link, and determines the first preset value, the second preset value and the third preset value according to the assembly link. Among them, the first light output information includes luminous flux and light intensity. Afterwards, the electronic device determines the light transmission efficiency of the optical fiber assembly according to the luminous flux in the first light output information and the luminous flux of the light source, and determines whether the light transmission efficiency is greater than the first preset value (for example, 50%). If the light transmission efficiency is less than the first preset value, it is determined that the optical fiber is excessively damaged. If the light transmission efficiency is greater than the first preset value, the electronic device determines the light intensity of each sub-region of the light output area according to the light intensity, and then determines whether the light intensity difference between each sub-region is less than the second preset value (for example, 25%). If there is a sub-region whose light intensity difference with other sub-regions is greater than the second preset value, it will be determined that the optical fiber of the sub-region is damaged. If the light intensity difference between each sub-region is less than the second preset value, the electronic device determines the local light intensity difference inside each sub-region. If the local light intensity difference inside each sub-region is less than the third preset value, it is determined that there is no area where the optical fiber is concentratedly damaged. If the local light intensity difference inside each sub-region is greater than the third preset value, it is determined that the local area with smaller light intensity is the area where the optical fiber is concentratedly damaged.
[0092] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
