Detailed implementation mode

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1:

[0029] This embodiment provides an image transmission device for discrete array optical signal detection, specifically as Figure 1 shown, including an input connector 1 of the image transmission optical cable, an output connector 2 of the image transmission optical cable, and an image transmission optical cable 3. The input connector 1 of the image transmission optical cable is connected to one end of the image transmission optical cable 3, and the output connector 2 of the image transmission optical cable is connected to the other end of the image transmission optical cable 3. The optical signal is input from the input connector 1 of the image transmission optical cable and is transmitted to the image transmission optical cable 3 through the output connector 2 of the image transmission optical cable for output; the input connector 1 of the image transmission optical cable is used to reduce the received image, and the output connector 2 of the image transmission optical cable is used to re-amplify the received image.

[0030] As Figure 2 shown, the input connector 1 of the image transmission optical cable includes an input housing and an input image transmission unit installed in the input housing. The input housing includes a tail fiber bundle outlet lead 101, an input ferrule nut 111, an input external thread hollow nut 105, and an input tapered ferrule 109. The input image transmission unit includes an optical fiber retainer 102 and an input image transmission light cone 104.

[0031] The pigtail bundle outlet lead wire device 101 is detachably connected to the input end ferrule nut 111, and the pigtail bundle outlet lead wire device 101 is detachably connected to the input end external thread hollow nut 105; the optical fiber retainer 102 and the input end image transmission optical cone 104 are both installed on the pigtail bundle outlet lead wire device 101; the input end ferrule nut 111 is provided with an input end tapered ferrule 109, and one end of the image transmission optical cable 3 is sleeved into the input end tapered ferrule 109; the input end external thread hollow nut 105 limits the optical fiber retainer 102, the input end image transmission optical cone 104, and the input end tapered ferrule 109 respectively.

[0032] The image transmission optical cable 3 is composed of an optical fiber bundle and an optical fiber bundle sheath; the optical fiber bundle includes multiple optical fibers, and the optical fibers in the optical fiber bundle are arranged end to end. The image transmission resolution is related to the number and diameter of the optical fibers in the optical fiber bundle. The more the number of optical fibers in the optical fiber bundle and the smaller the diameter of the optical fibers, the higher the image transmission resolution; the image transmission size is related to the combined diameter of the optical fiber bundle. The larger the combined diameter of the optical fiber bundle, the larger the size of the image supported for transmission.

[0033] When assembling the image transmission optical cable input end connector 1 and the image transmission optical cable 3, insert the optical fiber pigtail bundle of the photoconductive sensor passing through the pigtail bundle outlet lead wire device 101 into the optical fiber retainer 102; after grinding the optical fiber retainer 102 flat with a grinding machine, place it on the annular support boss inside the pigtail bundle outlet lead wire device 101, and then place the input end image transmission optical cone 104 in the pigtail bundle outlet lead wire device 101 so that the input end image transmission optical cone 104 is completely attached to the ground end face of the optical fiber retainer 102; at this time, buckle the input end external thread hollow nut 105 with the pigtail bundle outlet lead wire device 101 so that the input end external thread hollow nut 105 presses the optical fiber retainer 102 and the input end image transmission optical cone 104 respectively; then insert the input end ferrule nut 111 and the input end tapered ferrule 109 into the end of the image transmission optical cable 3 in sequence, and fix the input end tapered ferrule 109 to the end of the image transmission optical cable 3. Place the input end tapered ferrule 109 in the input end external thread hollow nut 105. The outer diameter of the input end tapered ferrule 109 matches the inner diameter of the input end external thread hollow nut 105 so that the input end image transmission optical cone 104 and the image transmission optical cable 3 on the input end tapered ferrule 109 are coaxial; then buckle the pigtail bundle outlet lead wire device 101 with the input end ferrule nut 111 so that the annular support boss in the input end ferrule nut 111 firmly presses the input end tapered ferrule 109 in the input end external thread hollow nut 105, completing the assembly of the image transmission optical cable input end connector 1 and the image transmission optical cable 3.

[0034] The optical fiber retainer 102 has via holes arranged in a regular hexagon, and the aperture size is adapted to receive the diameter of the optical fiber pigtail, so as to fix all the optical fiber pigtails and arrange the end faces of the pigtails at equal distances. The number of via holes is equal to the number of integrable optical waveguide signalers or sensors; multiple optical waveguide type signalers or sensors can be integrated simultaneously to collect and transmit images of the output end faces of the pigtails.

[0035] As Figure 3 shown, the output end connector 2 of the image transmission optical cable includes an output end housing and an output end image transmission unit installed in the output end housing. The output end housing includes a plug 201, an output end ferrule nut 210, an output end external thread hollow nut 206, and an output end tapered ferrule 208; the output end image transmission unit includes an output end image transmission light cone 205.

[0036] The plug 201 is detachably connected to the output end ferrule nut 210, and the plug 201 is detachably connected to the output end external thread hollow nut 206; the output end image transmission light cone 205 is installed on the plug 201; an output end tapered ferrule 208 is installed in the plug 201, and the other end of the image transmission optical cable 3 is sleeved into the output end tapered ferrule 208; the output end external thread hollow nut 206 limits the output end image transmission light cone 205 and the output end tapered ferrule 208 respectively.

[0037] When assembling the output end connector 2 of the image transmission optical cable and the image transmission optical cable 3, the output end image transmission light cone 205 is placed in the plug 201, and then the output end external thread hollow nut 206 is buckled with the plug 201, so that the output end external thread hollow nut 206 firmly presses the output end image transmission light cone 205 on the plug 201; the end of the image transmission optical cable 3 is sequentially inserted into the output end ferrule nut 210 and the output end tapered ferrule 208, and the end of the image transmission optical cable 3 is fixed to the output end tapered ferrule 208. Then, the output end tapered ferrule 208 is inserted into the output end external thread hollow nut 206. The inner diameter of the output end external thread hollow nut 206 matches the outer diameter of the output end tapered ferrule 208 to realize the coaxiality of the image transmission optical cable 3 on the output end image transmission light cone 205 and the output end tapered ferrule 208; then the output end ferrule nut 210 is buckled with the plug 201, so that the annular support boss in the output end ferrule nut 210 firmly presses the output end tapered ferrule 208 in the output end external thread hollow nut 206, completing the assembly of the output end connector 2 of the image transmission optical cable and the image transmission optical cable 3.

[0038] During operation, numerous receiving fiber optic pigtail bundles output image information to the input connector 1 of the image transmission optical cable. After the image information received at the input connector 1 of the image transmission optical cable is reduced, it is transmitted into the image transmission optical cable 3. The image transmission optical cable 3 transmits the reduced image information into the output connector 2 of the image transmission optical cable. The output connector 2 of the image transmission optical cable then enlarges the reduced image again and outputs it, thereby realizing the integrated processing of multiple signals.

[0039] Moreover, the input image transmission optical cone 104 and the output image transmission optical cone 205 have the same specifications. That is, after the input image transmission optical cone 104 reduces the image information by a certain ratio, the output image transmission optical cone 205 can enlarge the reduced image information back to the original size of the image information.

[0040] In summary, the technical solution of the present invention can integrate the output end faces of the tail fibers of multiple photoconductive signal devices or sensors, realize the centralized image acquisition and signal transmission of the signals output by the signal device or sensor array; there is no requirement for the functional performance consistency between the integrated photoconductive or sensors.

[0041] Through the image magnification and reduction functions of the input connector 1 of the image transmission optical cable and the output connector 2 of the image transmission optical cable, the size of the image transmission optical cable can be reduced, making its application scenario adaptability stronger.

[0042] Therefore, the technical solution of the present invention can effectively improve the integration degree of the distributed measurement system based on the discrete photoconductive signal device or sensor array, reduce the system complexity, and improve the measurement efficiency. And the entire device is composed of all-passive optical devices, with the characteristics of strong anti-interference and high reliability.

[0045] During assembly, first place the input anti-halo glass sheet 107 on the annular support boss inside the input external thread hollow nut 105, and then place the input tapered ferrule 109. The input ferrule nut 111 presses the input tapered ferrule 109 and the input anti-halo glass sheet 107 tightly. By setting the input anti-halo glass sheet 107, the stray light of the spot image can be filtered out and the halo can be eliminated, so as to improve the image clarity.
