[0038] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the following description, identical modules are denoted by identical reference numerals. In the case of identical reference numerals, their names and functions are also identical. Therefore, their detailed description will not be repeated.

[0039] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not constitute a limitation of the present invention.

[0040] Example 1

[0041] The present invention provides a slip ring device 100 integrating laser communication and laser countermeasure, see Figure 1 and Figure 2 , which includes: a hollow upper shell 20 and a hollow lower shell 10, wherein the inner cavity of the hollow lower shell 10 is sequentially installed with a first convex conical lens 11, a first concave conical lens 12, and a first triangular prism group 13, and the inner cavity of the hollow upper shell 20 is sequentially installed with a second triangular prism group 23, a second concave conical lens 22, and a second convex conical lens 21; the bottom end of the hollow upper shell 20 is connected to the top end of the hollow lower shell 10 through a bearing 30;

[0042] An external laser emitting device emits a laser countermeasure beam 50. The laser countermeasure beam 50 is used as an incident beam, which is split into a divergent beam by the first convex conical lens 11 and then enters the first concave conical lens 12. The divergent beam is split into a ring-shaped parallel beam by the first concave conical lens 12. The ring-shaped parallel beam passes through the first prism group and the second prism group in sequence, and is then split into a convergent beam by the second concave conical lens 22. The convergent beam enters the second convex conical lens 21 and is split into a parallel beam consistent with the incident beam.

[0043] The hollow lower shell 10 is provided with a first optical fiber interface 14 for connecting to the first triangular prism group 13 , and the hollow upper shell 20 is provided with a second optical fiber interface 24 for connecting to the second triangular prism group 23 .

[0044] As mentioned above, the external laser emitting device emits the laser countermeasure beam 50 . It is understandable that the laser countermeasure beam 50 can also be shaped and collimated by a reflector and then input into the first convex conical lens 11 as an incident beam.

[0045] Based on the characteristics of convex and concave conical lenses, it can be seen that after entering the first convex conical lens 11, the laser countermeasure beam 50 is split into a divergent beam. The divergent beam then enters the first concave conical lens 12 and is split into a ring-shaped parallel beam by the first concave conical lens 12. After passing through the first prism group and the second prism group, the ring-shaped parallel beam is split into a converging beam by the second concave conical lens 22. The converging beam then enters the second convex conical lens 21 and is restored to a parallel beam consistent with the incident laser countermeasure beam 50.

[0046] It can be understood that the annular parallel light beam remains in the state of an annular parallel light beam when passing through the first prism group and the second prism group. Therefore, there is a hollow channel of the light beam on the central axis of the annular parallel light beam.

[0047] Therefore, a first optical fiber interface 14 connected to the first triangular prism assembly 13 is provided on the hollow lower housing 10. The laser communication beam 40 transmitted by the external device enters the slip ring device 100 integrating laser communication and laser countermeasures through the first optical fiber interface 14. After being refracted within the first triangular prism assembly 13, it enters the center ring of the annular parallel beam and is transmitted to the second prism assembly. After being refracted within the second prism assembly, the laser communication beam 40 is output from the second optical fiber interface 24. Therefore, the laser countermeasure beam 50 and the laser communication beam 40 are coaxially transmitted within the slip ring device, and they are not affected or interfered with each other during transmission, thereby improving the efficiency of the laser countermeasure equipment.

[0048] In this embodiment, the top of the hollow upper housing 20 can be connected to the turntable of the laser countermeasure equipment, and the bottom of the lower housing can be connected to the base of the laser countermeasure equipment. Furthermore, the incident positions of the laser communication beam 40 and the laser countermeasure beam 50 are interchangeable. That is, the laser countermeasure beam 50 can be incident through the first fiber optic interface 14 and output through the second fiber optic interface 24; the laser communication beam 40 can be incident through the first convex conical lens 11 and output through the second convex conical lens 21.

[0049] Furthermore, the integrated laser communication and laser countermeasure slip ring device 100 of this embodiment can be used between two reflectors in the Kude optical path of laser countermeasure equipment. In another specific embodiment, a collimated laser can be directly connected to the hollow lower housing 10, and a receiving laser device can be connected to the hollow upper housing 20 to achieve laser beam transmission. Optical fibers can be connected to the first and second optical fiber interfaces 14 and 24.

[0050] Preferably, the housing further comprises a first pressing piece 15 and a second pressing piece 25 , wherein the first pressing piece 15 is mounted on the top surface of the hollow lower shell 10 , and the second pressing piece 25 is mounted on the bottom surface of the hollow upper shell 20 .

[0051] The above-mentioned structure may further include a first pressing ring 17 and a second pressing ring 27 . The first pressing ring 17 is mounted on the bottom surface of the hollow lower shell 10 , and the second pressing ring 27 is mounted on the top surface of the hollow upper shell 20 .

[0052] Preferably, it also includes a first spacer 16 and a second spacer 26, wherein the first spacer 16 is installed between the first convex conical lens 11 and the first concave conical lens 12, and the second spacer 26 is installed between the second convex conical lens 21 and the second concave conical lens 22.

[0053] Preferably, the outer ring of the bearing 30 is connected to the hollow lower shell 10 , and the inner ring of the bearing 30 is connected to the hollow upper shell 20 .

[0054] Preferably, the first triangular prism group 13 includes a first triangular prism 131 and a second triangular prism 132, the inclined surface of the first triangular prism 131 and the inclined surface of the second triangular prism 132 are in close contact with each other, one bottom surface of the first triangular prism 131 is in close contact with the first optical fiber interface 14, and the other bottom surface is in close contact with the first pressing plate 15;

[0055] The second triangular prism assembly 23 includes a third triangular prism 231 and a fourth triangular prism 232. The inclined surface of the third triangular prism 231 and the inclined surface of the fourth triangular prism 232 are in close contact with each other. One bottom surface of the fourth triangular prism 232 is in close contact with the second optical fiber interface 24, and the other bottom edge is in close contact with the second pressing plate 25.

[0056] The inclined surface of the first triangular prism 131 and the inclined surface of the fourth triangular prism 232 are arranged parallel to each other.

[0057] As described above, the laser communication beam 40 input by the first optical fiber interface 14 is transmitted to the first prism 131, refracted in a direction perpendicular to the first pressing plate 15 at the inclined surfaces of the first prism 131 and the second prism 132, and transmitted in the direction of the bottom surface of the first prism 131 close to the first pressing plate 15. It can be understood that in order for the laser communication beam 40 to be transmitted on the central axis of the circular ring of the annular parallel beam, in other words, in order for the laser communication beam 40 to be transmitted on the central axis of the slip ring device, the specific position of the first optical fiber interface 14 can correspond to the center position of the inclined surface of the first prism 131.

[0058] The refracted laser communication beam 40 is input from the first triangular prism 131 into the fourth triangular prism 232, where it is refracted at the inclined surface between the fourth triangular prism 232 and the third triangular prism 231, and then output horizontally toward the direction of the second optical fiber outlet of the fourth triangular prism 232, close to the second optical fiber outlet. Similarly, to ensure that the laser communication beam 40 can be transmitted along the central axis of the annular parallel beam, in other words, to ensure that the laser communication beam 40 can be transmitted along the central axis of the slip ring assembly, the specific position of the second optical fiber interface 24 can correspond to the center position of the inclined surface of the fourth triangular prism 232.

[0059] Therefore, the laser communication beam 40 is transmitted in the slip ring device, and the 360-degree rotation of the slip ring device does not affect the transmission of the laser communication beam 40, that is, the transmission of the laser communication beam 40 and the laser counter-beam 50 is realized while the 360-degree unrestricted rotation movement of the hollow upper shell 20 and the hollow lower shell 10 is realized.

[0060] Preferably, the cross-sections of the first triangular prism 131 , the second triangular prism 132 , the third triangular prism 231 , and the fourth triangular prism 232 are all right-angled isosceles triangles.
