Example 1

As shown in fig. 1 to 5, the scope provided by the present invention will now be described, which comprises a first objective lens group 1 and an eyepiece lens group 3 arranged in this order along a main optical axis 30, and a switching assembly 2, a reticle 4, a CMOS image sensor 71 and a display 8 arranged between the first objective lens group 1 and the eyepiece lens group 3; the switching assembly 2 is rotatable about a rotation centerline 70, wherein the rotation centerline 70 is perpendicular to the primary optical axis 30.

The reticle 4 and the display 8 are both arranged on the switching assembly 2, and the surface of the display 8 close to the rotation center line 70 is equal to the distance between the surface of the reticle 4 close to the rotation center line 70 and the rotation center line 70; the switching assembly 2 is used to bring the reticle 4 and the display 8 to switch between a first state and a second state. The reticle 4 may be made of glass or plastic, or may be made of other transparent materials, and may be selectively set according to actual needs.

A CMOS (Complementary Metal-Oxide-Semiconductor) image sensor 71 is provided to the display 8, and is electrically connected to the display 8. In this way, the CMOS image sensor 71 can be provided on the switching element 2 through the display 8. The CMOS image sensor 71 may convert the received light signal into a digital signal to be output and transmitted to the display 8, and then convert the digital signal into visual image information in the display 8, so that the user can aim in the near infrared night vision mode.

As shown in fig. 1, 4 and 5, in the first state, the white light path of the reticle 4 coincides with the main optical axis 30, the display 8 is deviated from the main optical axis 30, and the differentiation pattern of the reticle 4 is located on the combined focal plane 40 of the eyepiece 3 and the first objective lens 1, and at this time, the collimator is in the white light mode, and can perform the collimation in a scene where the ambient brightness is high in the daytime or at night.

As shown in fig. 2, 3, 6 and 7, in the second state, the reticle 4 is deviated from the main optical axis 30, the display 8 is located at the eyepiece focal plane 50 of the eyepiece group 3, the CMOS image sensor 71 is located at the first objective focal plane 60 of the first objective group 1, and at this time, the collimator is in the near infrared night vision mode, and the CMOS image sensor 71 can convert the received optical signal into a digital signal to output to the display 8, and then convert the digital signal into visual image information in the display 8, so that the user can aim at night in a scene with low ambient brightness.

The sighting telescope satisfies the following relationship:

d ₂ ＝d ₁ /n；

d ₁ represents the thickness of the reticle 4 on the white light path, d ₂ Representing the overall thickness of the CMOS image sensor 71 and the display 8 in the night vision path, n represents the refractive index of the reticle 4, e.g. when the material of the reticle 4 is glassWhen n represents the refractive index of the glass material. After the above relation is satisfied, since the wavelength range of the visible light of the human eye is 380 nm to 1550 nm, the wavelength range of the visible light of the human eye is 380 nm to 780 nm, and the near infrared wavelength range is 780 nm to 2526 nm, the CMOS image sensor 71 can recognize the visible light of the human eye and a part of the near infrared light, and thus the CMOS image sensor 71 and the reticle 4 can share the first objective lens group 1. By rotating the switching assembly 2 around the rotation center line 70, the reticle 4 and the CMOS image sensor 71 are driven to switch between the first state and the second state, and switching between the white light mode and the near infrared night vision mode can be achieved without changing the positions and structures of the first objective lens group 1 and the eyepiece group 3, that is, the white light mode and the near infrared night vision mode can share the structures and positions of the first objective lens group 1 and the eyepiece group 3, so that the white light mode and the near infrared night vision mode can be achieved without excessively increasing the volume of the sighting telescope.

Here, the "thickness of the reticle 4 on the white light path" referred to in the present application refers to the thickness of the reticle 4 along the main optical axis 30 in the first state, as shown in fig. 1; the "thickness of the CMOS image sensor 71 and the display 8 on the night vision optical path" referred to in the present application refers to the overall thickness of the CMOS image sensor 71 and the display 8 in the direction of the main optical axis 30 in the second state, as shown in fig. 2.

Compared with the prior art, the sighting telescope provided by the embodiment has the advantages that the CMOS image sensor 71 is arranged on the display 8 and is electrically connected with the display 8, so that the sighting telescope has a near infrared night vision mode, and a user can aim at a scene with lower ambient brightness at night. The switching assembly 2 rotates around the rotation center line 70 to drive the dividing plate 4 and the display 8 to be switched between the first state and the second state, so that the fast switching of the white light mode and the near infrared night vision mode is realized, the cost of the sighting telescope can be reduced, the sighting telescope is convenient and quick to use, and delay time and fighter delay can be avoided; meanwhile, the sighting telescope does not need to be replaced or corrected when the mode is switched, so that installation errors caused by replacing the sighting telescope or correcting the sighting telescope can be avoided. The overall thickness of the CMOS image sensor 71 and the display 8 on the night vision optical path is set to be equal to the ratio of the thickness of the reticle 4 on the white light optical path to the refractive index of the reticle 4, so that the white light mode and the near infrared night vision mode can share the structure and position of the first objective lens group 1 and the eyepiece group 3 without changing the positions and structures of the first objective lens group 1 and the eyepiece group 3, thereby realizing that the white light mode and the near infrared night vision mode are simultaneously possessed without excessively increasing the volume of the scope.

In one embodiment, as shown in FIG. 3, in the second state, the display 8 is located at the destination of the CMOS image sensor 71. In this way, after the sighting telescope is switched from the white light mode to the near infrared night vision mode, the display 8 can be prevented from shielding the main light path to cause the failure of the sighting function.

As shown in fig. 4 and 5, in the first state, the night vision optical path of the CMOS image sensor 71 is deviated from the main optical axis 30, so that the interference of the CMOS image sensor 71 with the reticle 4 can be avoided in the white light mode, and the interference of the reticle 4 with the CMOS image sensor 71 can be avoided in the night vision mode. Specifically, in the first state, the angle of deviation between the night vision optical path of the CMOS image sensor 71 and the main optical axis 30 may be selected and set according to actual needs, as long as the interference of the CMOS image sensor 71 on the reticle 4 in the white light mode can be avoided, and preferably, when the angle of deviation between the night vision optical path of the CMOS image sensor 71 and the main optical axis 30 is 90 °, that is, when the night vision optical path of the CMOS image sensor 71 is perpendicular to the main optical axis 30, the interference of the CMOS image sensor 71 on the reticle 4 can be reduced to the maximum extent. Similarly, in the second state, that is, in the second state, the white light path of the reticle 4 is perpendicular to the main optical axis 30, the interference of the reticle 4 to the CMOS image sensor 71 can be minimized.

In one embodiment, as shown in fig. 4 and 5, the switching assembly 2 includes a rotating base 21 and a switching handle 22, and the reticle 4 and the display 8 are disposed on the rotating base 21; the sighting telescope further comprises a lens body 9, and the first objective lens group 1, the ocular lens group 3, the reticle 4 and the CMOS image sensor 71 are all positioned in the lens body 9; the rotating seat 21 is rotatably connected to the mirror body 9, and extends out of the mirror body 9 to be fixedly connected with the conversion handle 22, and the conversion handle 22 drives the rotating seat 21 to rotate around a rotation center line 70 perpendicular to the main optical axis 30, so as to drive the reticle 4 and the display 8 to switch between a first state and a second state.

The reticle 4 and the display 8 are arranged on the rotating seat 21 at intervals, in practical application, the specific shape of the rotating seat 21 can be selected and arranged according to practical needs, for example, the rotating seat 21 can be cylindrical, and at this time, the reticle 4 and the display 8 are arranged on the side wall of the rotating seat 21 at intervals along the circumferential direction; for another example, the rotating base 21 may be hexahedral, and the reticle 4 and the display 8 are respectively located on two end surfaces of the rotating base 21 parallel to and adjacent to the rotation center line 70, so long as the rotating base 21 can rotate around the rotation center line 70, and a person skilled in the art can select and set the rotating base according to actual needs.

In practical applications, as shown in fig. 5, an adjusting ring 100 may be disposed between the display 8 and the rotating base 21, so that the distance between the rotation center line 70 and the reticle 4 is equal to the distance between the rotation center line 70 and the display 8.

The second objective lens group 72 and the thermal imaging core 73 are disposed in order along a straight line parallel to the main optical axis 30. Since the detector 731 of the thermal imaging core 73 recognizes that the light wave with the wavelength of 8 micrometers to 14 micrometers is a light wave, the light wave transmitted through the wavelength is different from the lens material used for the light wave transmitted through the visible light, so that the thermal imaging core 73 and the white sighting telescope cannot share the first objective lens group 1, and the second objective lens group 72 needs to be separately arranged. The second objective lens group 72 and the thermal imaging core 73 are sequentially arranged along a straight line parallel to the main optical axis 30, so that it is ensured that the target image information obtained by the first objective lens group 1 and the second objective lens group 72 is consistent when the user performs aiming in the white light mode and the thermal imaging night vision mode.

The thermal imaging core 73 includes a detector 731 and a signal processing unit 732, the detector 731 is disposed at one end of the signal processing unit 732 near the second objective lens group 72, and is electrically connected to the signal processing unit 732, and the signal processing unit 732 is electrically connected to the display 8.

As shown in fig. 2, 6 and 7, in the second state, the reticle 4 is deviated from the main optical axis 30, the display 8 is located at the eyepiece focal plane 50 of the eyepiece set 3, the detector 731 is located at the second objective focal plane of the second objective set 72, at this time, the scope is in the thermal imaging night vision mode, the thermal imaging core 73 can collect image information in the night vision mode and convert the thermal information into digital information, and the display 8 receives the digital information of the thermal imaging core 73 and converts it into visual image information, so that the user can aim in a scene with low ambient brightness at night.

The CMOS image sensor 71 is provided on the display 8, and is electrically connected to the display 8. In this way, the CMOS image sensor 71 can be provided on the switching element 2 through the display 8. The CMOS image sensor 71 may convert the received light signal into a digital signal to be output and transmitted to the display 8, and then convert the digital signal into visual image information in the display 8, so that the user can aim in the near infrared night vision mode.

As shown in fig. 2, 6 and 7, in the second state, the reticle 4 is deviated from the main optical axis 30, the display 8 is located at the eyepiece focal plane 50 of the eyepiece unit 3, the CMOS image sensor 71 is located at the first objective focal plane 60 of the first objective unit 1, and since the CMOS image sensor 71 and the signal processing unit 732 of the thermal imaging core 73 are electrically connected to the display 8, the sighting telescope has both the near infrared night vision mode and the thermal imaging night vision mode, and in practical application, a button for switching the near infrared night vision mode and the thermal imaging night vision mode may be configured on the sighting telescope, and the user selects different night vision modes through the button, so that the user can aim in a scene with low ambient brightness at night.

The sighting telescope satisfies the following relationship:

d ₂ ＝d ₁ /n；

d ₁ represents the thickness of the reticle 4 on the white light path, d ₂ Indicating the overall thickness of the CMOS image sensor 71 and the display 8 on the night vision optical path, n indicating the refractive index of the reticle 4, for example, when the material of the reticle 4 is glass, n indicating the refractive index of the glass material. After the above relation is satisfied, since the wavelength range of visible light of the human eye is 380 nm to 1550 nm, the wavelength range of visible light of the human eye is 380 nm to 780 nm, and the near infrared wavelength range is 780 nm to 2526 nm, the CMOS image sensor 71 can recognize visible light of the human eye and a part of near infrared light, and thus the CMOS image sensor 71 and the reticle 4 can share the first objective lens group 1. By rotating the switching assembly 2 around the rotation center line 70, the reticle 4 and the CMOS image sensor 71 are driven to switch between the first state and the second state, and switching between the white light mode and the near infrared night vision mode can be achieved without changing the positions and structures of the first objective lens group 1 and the eyepiece group 3, that is, the white light mode and the near infrared night vision mode can share the structures and positions of the first objective lens group 1 and the eyepiece group 3, so that the white light mode and the near infrared night vision mode can be achieved without excessively increasing the volume of the sighting telescope.

Here, the "thickness of the reticle 4 on the white light path" referred to in the present application refers to the thickness of the reticle 4 along the main optical axis 30 in the first state, as shown in fig. 1; the "total thickness of the CMOS image sensor 71 and the display 8 on the night vision optical path" referred to in the present application refers to the total thickness of the CMOS image sensor 71 and the display 8 in the direction of the main optical axis 30 in the second state, as shown in fig. 2.

The second objective lens group 72 and the thermal imaging core 73 are disposed in order along a straight line parallel to the main optical axis 30. Since the detector 731 of the thermal imaging core 73 recognizes that the light wave with the wavelength of 8 micrometers to 14 micrometers is a light wave, the light wave transmitted through the wavelength is different from the lens material used for the light wave transmitted through the visible light, so that the thermal imaging core 73 and the white sighting telescope cannot share the first objective lens group 1, and the second objective lens group 72 needs to be separately arranged. The second objective lens group 72 and the thermal imaging core 73 are sequentially arranged along a straight line parallel to the main optical axis 30, so that it is ensured that when a user performs aiming in the near infrared night vision mode and the thermal imaging night vision mode, the target image information obtained by the first objective lens group 1 and the second objective lens group 72 is consistent.

Compared with the prior art, the sighting telescope provided by the embodiment has the advantages that the CMOS image sensor 71 is arranged on the display 8 and is electrically connected with the display 8, so that the sighting telescope has a near infrared night vision mode and a thermal imaging night vision mode, a user can aim at a scene with low ambient brightness at night, and different night vision modes can be selected as required. The switching assembly 2 rotates around the rotation center line 70 to drive the dividing plate 4 and the display 8 to be switched between the first state and the second state, so that the fast switching of the white light mode and the night vision mode is realized, the cost of the sighting telescope can be reduced, the sighting telescope is convenient and quick to use, and delay time and fighter delay can be avoided; meanwhile, the sighting telescope does not need to be replaced or corrected when the mode is switched, so that installation errors caused by replacing the sighting telescope or correcting the sighting telescope can be avoided. The overall thickness of the CMOS image sensor 71 and the display 8 on the night vision optical path is set to be equal to the ratio of the thickness of the reticle 4 on the white light optical path to the refractive index of the reticle 4, so that the white light mode and the near infrared night vision mode can share the structure and position of the first objective lens group 1 and the eyepiece group 3 without changing the positions and structures of the first objective lens group 1 and the eyepiece group 3, thereby realizing that the white light mode and the near infrared night vision mode are simultaneously possessed without excessively increasing the volume of the scope.

As shown in fig. 4 and 5, in the first state, the night vision optical path of the CMOS image sensor 71 is deviated from the main optical axis 30, so that interference of the CMOS image sensor 71 with the reticle 4 can be avoided in the white light mode, and interference of the reticle 4 with the CMOS image sensor 71 can be avoided in the night vision mode. Specifically, in the first state, the angle of deviation between the night vision optical path of the CMOS image sensor 71 and the main optical axis 30 may be selected and set according to actual needs, as long as the interference of the CMOS image sensor 71 on the reticle 4 in the white light mode can be avoided, and preferably, when the angle of deviation between the night vision optical path of the CMOS image sensor 71 and the main optical axis 30 is 90 °, that is, when the night vision optical path of the CMOS image sensor 71 is perpendicular to the main optical axis 30, the interference of the CMOS image sensor 71 on the reticle 4 can be reduced to the maximum extent. Similarly, in the second state, that is, in the second state, the white light path of the reticle 4 is perpendicular to the main optical axis 30, the interference of the reticle 4 to the CMOS image sensor 71 can be minimized.
