Description

[0002] The optical path of the laser ranging telescope is composed of the telescope optical path (natural light optical path) and the laser ranging optical path (laser emission optical path plus laser receiving optical path).

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0038] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0039] like Figure 1-6 As shown in Figures 9 and 10, a laser ranging telescope 100 with switchable magnification according to an embodiment of the present invention comprises a main body 10 and an optical element disposed in the main body 10. The main body 10 is the shell of the laser ranging telescope 100. The main body 10 defines a laser channel 14 and a first optical path channel 11 and a second optical path channel 12 arranged in parallel along the axial direction. The axial direction is the direction from the target object to the laser ranging telescope 100. The laser channel 14 is used to transmit laser, and the first optical path channel 11 and the second optical path channel 12 are used to transmit natural light. Figure 3 As shown, a through hole 131 is provided at the junction of the first optical path channel 11 and the second optical path channel 12, so that the first optical path channel 11 and the second optical path channel 12 can be communicated.

[0040] like Figure 6 As shown, a first objective lens group 111 is provided at one end of the first optical path channel 11 close to the target object, which is used to magnify the target object at a first magnification. Correspondingly, a second objective lens group 121 is also provided at one end of the second optical path channel 12 close to the target object, which is used to magnify the target object at a second magnification. An eyepiece group 112 is provided at the other end of the first optical path channel 11, which is used to magnify the target object and form a target image. A prism group 114 is also provided in the first optical path channel 11, which is arranged close to the eyepiece group. After natural light is focused by the first objective lens group or the second objective lens group, it is reversed to the eyepiece group 112 through the prism group 114 to form an image.

[0041] In this embodiment, the magnification of the first objective lens group 111 is 6 times, and the magnification of the second objective lens group 121 is 10 times. The second objective lens group 121 is closer to the target object in the axial direction relative to the first objective lens group 111. In other embodiments, the magnifications of the first objective lens group 111 and the second objective lens group 121 can also be set according to actual needs.

[0042] A reflective switching plate 132 is also provided in the first optical path channel 11. A rotating shaft 1321 is provided at the first end of the reflective switching plate 132, which is engaged and exposed to the main body 10, and is used to rotate the reflective switching plate 132. The other end of the reflective switching plate 132 is a rotatable free end. The reflective switching plate 132 can be rotated to a first position to close the through hole 131, or to a second position. When the reflective switching plate 132 is in the first position, it is attached to the inner wall of the first optical path channel 11. The free end of the reflective switching plate 132 is arranged closer to the eyepiece group 112 relative to the rotating shaft 1321. When the reflective switching plate 132 is in the second position, its free end abuts against the inner wall of the first optical path channel 11 on the side away from the second optical path channel 12, so that the reflective switching plate 132 is tilted relative to the axis of the first optical path channel 11 as a whole. Thus, natural light entering the second optical path channel 12 can be reflected by the optical component and then reflected to the first optical path channel 11 by the reflective switching plate 132. Preferably, a limiting step is provided on the inner wall of the first optical path channel 11 away from the second optical path channel 12 to fix the reflective switching plate 132 in the second position.

[0043] like Figure 8 As shown, when the reflective switching plate 132 is in the first position, the natural light emitted by the target object is focused by the first objective lens group 111 into the first optical path channel 11, and is transmitted through the first dichroic mirror 115, and is reflected by the prism group 114 to the eyepiece group to form an image. At this time, the observer sees the image magnified by the first objective lens group, the eyepiece group 112, and the eyepiece group 113. Figure 7As shown, when the reflective switching plate 132 is in the second position, the natural light emitted by the target object is focused by the second objective lens group 121 into the second optical path channel 12, and is reflected by the reflective switching plate 132 into the first optical path channel 11, and then is imaged by the prism group 114 after being turned to the eyepiece group. At this time, the observer sees the image magnified by the second objective lens group, the prism group 114 and the eyepiece group 112. The telescope of this embodiment controls the optical path channel through which the natural light entering the eyepiece group passes by by arranging a rotatable reflective switching plate 132 between the first optical path channel 11 and the second optical path channel 12, thereby switching the magnification of the telescope without affecting the transmission and ranging of the laser.

[0044] like Fig. 9 As shown, the laser channel 14 includes a laser emission channel 15 and a laser receiving channel 16 , wherein the laser emission channel 15 at least partially overlaps with the second optical path channel 12 , and the laser receiving channel 16 at least partially overlaps with the first optical path channel 11 .

[0045] Specifically, in this embodiment, a laser emitter 151 is provided in the first optical path channel 11 for emitting laser light. A first dichroic mirror 115 is also provided in the first optical path channel 11 for reflecting laser light and transmitting natural light. The laser light emitted by the laser emitter 151 is reflected by the first dichroic mirror 115 and emitted out of the first optical path channel and transmitted to the target object. The reflector 122 in the second optical path channel 12 is a second dichroic mirror for reflecting natural light and transmitting laser light. A laser receiver 161 is also provided at the other end of the second optical path channel 12 for receiving laser light. Preferably, the emitting end of the laser emitter 151 and the receiving end of the laser receiver 161 are respectively provided with a first laser coupling mirror 154 and a second laser coupling mirror 162 for converging and collimating laser light.

[0046] Please refer again Figure 6 The first dichroic mirror 115 is located between the first objective lens group 111 and the eyepiece lens group 112, and the first dichroic mirror 115 is tilted relative to the axial direction of the first optical path. The first laser reflection mirror 152 and the second laser reflection mirror 153 are respectively arranged on both sides of the first dichroic mirror 115, and the positions of the first laser reflection mirror 152 and the second laser reflection mirror 153 do not interfere with the transmission of natural light entering the first optical path 11. The first laser emission mirror is located between the reflective switching plate 132 and the first objective lens group 111, and is used to reflect the laser emitted by the laser emitter 151 to the second laser reflection mirror 153. The second laser reflection mirror 153 is used to reflect the laser reflected by the first laser reflection mirror 152 to the first dichroic mirror 115.

[0047] The direction in which the laser emitter 151 emits laser light is perpendicular to the axial direction of the laser ranging telescope 100. The laser light emitted by the laser emitter 151 is reflected by the first laser reflecting mirror 152 and the second laser reflecting mirror 153 in sequence (see Figure 4 ), and then reflected by the first dichroic mirror 115, and then emitted from the first optical path channel 11 and transmitted to the target object, forming a laser emission optical path (see Fig. 9 ). The laser reflected by the target enters the second optical path channel 12 and passes through the second dichroic mirror that is transparent to laser light, and is received by the laser receiver 161 behind it, forming a laser receiving optical path. It can be seen that the deflection of the reflective switching plate 132 does not affect the transmission of the laser optical path. Please refer to the prior art for the principle of laser ranging, which will not be elaborated here.

[0048] In this embodiment, the reflective switching plate 132 is arranged closer to the eyepiece group than the first dichroic mirror 115, so that the deflection of the reflective switching plate 132 does not affect the transmission of the laser in the first optical path channel 11. And the tilt direction of the first dichroic mirror 115 relative to the axial direction is consistent with the tilt direction of the reflective switching plate 132 when it is located at the second position. In this way, the laser emitted by the laser emitter 151 can be reflected by the first laser reflecting mirror 152, the second laser reflecting mirror 153 and the first dichroic mirror 115 in sequence, and then can be emitted from the first optical path channel 11 to reach the target object.

[0049] Preferably, the inclination of the reflective switching plate 132 is the same as that of the second dichroic mirror. Thus, natural light entering the second optical path 12 along the axial direction can continue to enter the prism assembly 114 along the axial direction after being reflected by the second dichroic mirror and the reflective switching plate 132.

[0050] A digital imaging module is also provided in the main body 10. The digital imaging module can be arranged between the prism group 114 and the laser receiver 161. The digital imaging module is connected to the laser receiver 161, and is used to process the laser received by the laser receiver 161 into a digital image, and merge the digital image into the prism group 114 and form an image at the eyepiece group 112. In this way, when the user observes the target object with the telescope, the image of the target object and the distance value between the target object and the telescope can be displayed at the eyepiece group 122 at the same time. Preferably, the laser receiver 161 is closer to the target object in the axial direction relative to the eyepiece group 112, so that the axial length of the first optical path channel 11 is greater than that of the second optical path channel 12.

[0051] Fig.10The laser ranging telescope 200 of the second embodiment of the present application is shown, which is similar to the first embodiment, and the only difference is the position of the laser emitter 251 and the laser receiver 261. In this embodiment, the laser emitter 251 is located at the other end of the second optical path channel 22 relative to the second objective lens group 221, and the laser receiver 261 is located in the first optical path channel 11 and between the first objective lens group 211 and the reflective switching plate 232. At this time, the natural light path of this embodiment is the same as that of the first embodiment, the laser emission light path is opposite to the laser receiving light path of the first embodiment, and the laser receiving light path is opposite to the laser emission light path of the first embodiment.

[0052] Fig.12 FIG. 3 shows a laser rangefinder telescope 300 of the third embodiment of the present application, which is similar to the first embodiment, except that it also includes a laser reflector group, and the position of the laser receiver 361 is also different. In this embodiment, the laser receiver 361 is located at the second optical path channel 32 and is arranged close to the second objective lens group 221, and its position does not interfere with the natural light entering the second optical path channel 32. In addition, the laser receiver 361 is located on the inner wall of the second optical path channel away from the first optical path channel 31. A laser reflector group is also provided in the second optical path channel 32, including a third laser reflector 363, a fourth laser reflector 364 and a second dichroic mirror 365, and the second dichroic mirror 365 is used to reflect laser light and transmit natural light. The laser reflector group is located between the reflector 322 and the second objective lens group 321. In this embodiment, the laser emission optical path is the same as the laser emission optical path of the first embodiment. After the laser reflected by the target enters the second optical path channel 32, it is reflected by the second dichroic mirror 365 and the fourth laser reflector 364 in turn (see attached Fig.11 The laser receiving optical path) is then reflected by the third laser reflecting mirror 363 and received by the laser receiver 361 (see attached Fig.12 In this embodiment, since the laser does not pass through the reflector 322, the reflector 322 can be a reflector that can reflect natural light.

[0053] Fig.13 The laser ranging telescope 400 of the fourth embodiment of the present application is shown, which is similar to the first optical path channel and the second optical path channel of the first embodiment, except that the laser ranging optical path is independent of the natural light optical path. As can be seen from the figure, the laser receiver 451 and the laser transmitter 456 are independently arranged from the first optical path channel 41 and the second optical path channel 42.

[0054] Fig.14The fifth embodiment of the present application shows a laser ranging telescope 500, which is similar to the first or second embodiment, except that the laser emitter 551 is independently provided from the first optical path channel 51 and the second optical path channel 52, that is, the laser emission optical path is independently provided from the natural light optical path. In this case, the first optical path channel or the second optical path channel can also serve as a laser receiving channel. The laser receiving optical path of this embodiment is the same as that of the first embodiment, see the attached Fig. 9 , or the direction of the laser emission light path is opposite to that of the second embodiment.

[0055] Fig.15 The sixth embodiment of the laser rangefinder telescope 600 of the present application is shown, which is similar to the first or second embodiment, except that the laser receiver 661 is set independently of the first optical path channel 61 and the second optical path channel 62, that is, the laser receiving optical path is set independently of the natural light optical path. In this case, the first optical path channel 61 or the second optical path channel 62 can also serve as a laser emission channel. The laser emission optical path of this embodiment is the same as the laser emission optical path of the first embodiment, see the attached Fig. 9 , or the direction of the laser receiving optical path is opposite to that of the second embodiment.

[0056] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
