Description

Technical Field

[0001] The invention relates to the technical field of telescopes, and in particular to a combined variable-magnification telescope system. Background Art

[0002] At present, the two monocular telescopes in the existing binoculars structure are usually detachable and can be formed into a telescope, a monocular telescope or a binoculars according to needs. For example, the existing binoculars can be disassembled into two monocular telescopes, and the two monocular telescopes can be axially connected by a sleeve to form a telescope, and the telescope can be connected to the camera of a mobile phone through a sleeve with a through hole.

[0003] In fact, when two monocular telescopes are axially connected to form binoculars, the entrance pupil diameter of the telescope system does not increase, and the telescopic magnification cannot be superimposed. Moreover, when the monocular telescopes are spliced ​​into a telescope, the entrance pupil diameter of the telescope system is the entrance pupil diameter of the monocular telescope, and the exit pupil diameter is reduced by n times (n is the magnification of the first monocular telescope and the second monocular telescope), which is too different from the exit pupil diameter adapted to the human eye, resulting in difficulty and discomfort for the human eye to watch. Therefore, a combined variable magnification telescope system is proposed to solve the above problems. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a combined variable-magnification telescopic system having the advantages of superimposing the telescopic magnifications of two monocular telescopes and a telescope, increasing the observation distance, etc., thus solving the problem that the existing binoculars cannot achieve telescopic magnification superposition.

[0005] The technical solution adopted by the present invention to solve the above technical problems is as follows:

[0006] Provided is a combined variable-power telescope system, comprising a first monocular telescope, a second monocular telescope and a lens group, wherein the first monocular telescope and the second monocular telescope can be used as monocular telescopes individually, and the first monocular telescope and the second monocular telescope can form one of binoculars or telescopes; wherein, when the first monocular telescope and the second monocular telescope form a telescope, the first monocular telescope, the second monocular telescope and the lens group are coaxially arranged along an observation optical path, and the second monocular telescope is arranged at the eyepiece end of the first monocular telescope, the lens group is arranged at the objective end of the first monocular telescope, and a coaxial laser transmitting and receiving module is arranged inside the second monocular telescope.

[0007] Furthermore, a first objective lens group, a first prism group and a first eyepiece group are coaxially arranged in sequence along the natural incident light path inside the first monocular telescope.

[0008] Furthermore, a second objective lens group, a second prism group, an LCD display screen, and a second eyepiece group are coaxially arranged in sequence along the natural incident light path inside the second monocular telescope; an OLED projection module is also arranged inside the second monocular telescope.

[0009] Furthermore, the first objective lens group and the second objective lens group are respectively composed of cemented lenses, the second prism group and the second prism group respectively include a compensation prism, a half-penta prism and a Schmidt roof prism, and the first eyepiece group and the second eyepiece group are respectively composed of a cemented lens and a single lens.

[0010] Furthermore, the coaxial laser transmitting and receiving module includes a laser transmitter; the laser transmitter is used to transmit laser, and along the optical path of the transmitted laser, the second focusing lens, the perforated reflector and the splicing lens are respectively arranged in sequence; along the optical path of the diffusely reflected echo laser, the first focusing lens and the laser receiver are respectively arranged in sequence.

[0011] Furthermore, the lens group consists of a cemented lens and two single lenses.

[0012] Furthermore, when the first monocular telescope and the second monocular telescope form a binocular telescope, the connecting member therebetween is a lens barrel hinge axis.

[0013] Furthermore, when the first monocular telescope and the second monocular telescope form a telescope, the connecting piece between the two can be any one of a connecting sleeve and a connecting ring.

[0014] Furthermore, the first monocular telescope and the second monocular telescope each independently have a focusing device. When the first monocular telescope and the second monocular telescope form a binoculars, the first monocular telescope and the second monocular telescope share an external focusing structure, wherein the external focusing structure is formed by combining the two focusing devices through a connecting component.

[0015] According to the above embodiment of the combined variable-power telescope system of the present invention, the first monocular telescope, the second monocular telescope and the lens group are included. The first monocular telescope and the second monocular telescope can be used as monoculars separately, and the first monocular telescope and the second monocular telescope can form one of binoculars or telescopes. Through the above detachable binocular telescope structure, the multiple functions of telescopes, monocular telescopes, binoculars and mobile phone telescopes can be integrated into one. In this way, when the first monocular telescope and the second monocular telescope form a telescope, the first monocular telescope, the second monocular telescope and the lens group are coaxially arranged along the observation optical path, and the second monocular telescope is arranged at the eyepiece end of the first monocular telescope, and the lens group is arranged at the objective end of the first monocular telescope. Through the arrangement of the lens group, the amount of light entering the telescopic optical system of the telescope can be increased, thereby increasing the entrance pupil diameter and exit pupil diameter of the telescopic optical system, realizing the superposition of telephoto magnifications of the telescope system, improving the resolution, and increasing the observation distance, so that the problem of difficulty and discomfort in viewing for the human eye will not occur. In addition, by adding a lens group, the superposition of telephoto magnifications of the two monocular telescopes can also be achieved to increase the observation distance.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Please refer to Figures 1 to 5A combined variable-power telescope system provided by an embodiment of the present invention comprises a first monocular telescope (1), a second monocular telescope (2) and a lens group (4); the first monocular telescope (1) and the second monocular telescope (2) can be used as monocular telescopes independently, and the first monocular telescope (1) and the second monocular telescope (1) can be combined into a binocular telescope or a telescope; thus, the multiple functions of a telescope, a monocular telescope, a binocular telescope and a mobile phone telescope can be integrated into one by the above-mentioned detachable binocular telescope structure, so as to realize the use in different occasions; when the first monocular telescope (1) and the second monocular telescope (2) are combined into a telescope, the first monocular telescope (1) and the second monocular telescope (1) The lens group (4) is coaxially arranged along the observation optical path, and the second monocular telescope (2) is arranged at the eyepiece end of the first monocular telescope (1), and the lens group (4) is arranged at the objective end of the first monocular telescope (1). A coaxial laser transmitting and receiving module (3) is arranged inside the second monocular telescope (2). In this way, by setting the lens group (4), the amount of light entering the telescopic optical system of the telescope can be increased, thereby increasing the entrance pupil diameter and exit pupil diameter of the telescopic optical system, achieving the superposition of the telescopic multiples of the telescopic system, improving the resolution, and increasing the observation distance, so that the problem of difficulty and discomfort in viewing for the human eye will not occur. In addition, by adding the lens group (4), the superposition of the telescopic multiples of the two monocular telescopes can also be achieved, thereby increasing the observation distance.

[0027] In this embodiment, the first monocular telescope (1) is provided with a first objective lens group (101), a first prism group (102) and a first eyepiece group (103) coaxially in sequence along the natural incident light path; the second monocular telescope (2) is provided with a second objective lens group (201), a second prism group (202), an LCD display screen (203) and a second eyepiece group (204) coaxially in sequence along the natural incident light path; the second monocular telescope (2) is also provided with an OLED projection module, the OLED projection module comprising an OLED display screen (205) and a projection lens group (206); thus, when the first monocular telescope (1) and the second monocular telescope (2) are spliced ​​into a telescope, the lens group (4) can be arranged to form a telescope. The invention can increase the amount of light entering the telescopic optical system, thereby increasing the entrance pupil diameter and exit pupil diameter of the telescopic optical system. In this way, the optical path diagram of the telescopic optical system is specifically as follows: when the light emitted by the target object enters the lens group (4), the first objective lens group (101), the first prism group (102), the first eyepiece group (103) and the second objective lens group (1) are equivalent to the objective lens part of the entire telescopic optical system, and focus the light emitted by the target object. The focused light forms a real image at the position of the LCD display screen (203) through the second prism group (202), so that the human eye can observe through the second eyepiece group (204), thereby realizing the telephoto multiple superposition of the telescopic system, improving the resolution, and increasing the observation distance, so that the problem of difficulty and discomfort in viewing by the human eye will not occur.

[0028] In this embodiment, the lens group (4) is composed of a cemented lens (401) and two single lenses (402), wherein the cemented lens (401) is used to increase the entrance pupil diameter of the telescopic system of the telescope, and the two single lens cemented lenses (402) are used to increase the exit pupil diameter of the telescopic system of the telescope, so as to achieve a magnification effect.

[0029] In this embodiment, the first objective lens group (101) and the second objective lens group (201) are respectively composed of cemented lenses, the first eyepiece group (103) and the second eyepiece group (204) are respectively composed of cemented lenses and single lenses, and the first prism group (102) and the second prism group (202) respectively include a compensation prism, a half-pentagonal prism and a Schmidt roof prism.

[0030] In this embodiment, the coaxial laser transmitting and receiving module (3) comprises a laser transmitter (301), a first focusing lens (305), a second focusing lens (302), a reflector with a hole (303), a splicing lens (304) and a laser receiver (306); the laser transmitter (301) is used to transmit laser light, and along the optical path of the transmitted laser light, the second focusing lens (302), the reflector with a hole (303) and the splicing lens (304) are respectively arranged in sequence; along the optical path of the diffusely reflected echo laser light, the first focusing lens (305) and the laser receiver (306) are respectively arranged in sequence, so that when the first monocular telescope (1) and the second monocular telescope (2) are spliced ​​into a telescope, the optical path diagram of the laser transmitting system is as follows: Figure 2 Specifically, the infrared light emitted by the laser emitter (301) passes through the second focusing lens (302), and then enters the splicing lens (304) through the central circular hole of the perforated reflector (303) to perform the first collimation of the light beam. The collimated laser light beam passes through the compensation prism of the second prism group (202), and then enters the second objective lens group (201) for secondary collimation after being reflected by the semi-pentagonal prism. The light beam after secondary collimation enters the first monocular telescope (1) and the lens group (4) with a smaller divergence angle for tertiary collimation, and is emitted as nearly parallel light to hit the object to be measured. The optical path diagram of the laser receiving system is shown in FIG. Figure 3 As shown, specifically: when the infrared laser hits the object to be measured, diffuse reflection will occur, and the diffusely reflected echo laser will be converged by the lens group (4) and the first monocular telescope (1), and the converged echo laser will be converged again by the second objective lens group (201), and the converged light beam will be reflected by the second prism group (202), and after being focused by the outer ring lens of the spliced ​​lens (304), the perforated reflector (303) will be reflected again, and finally focused by the first focusing lens (305) into a smaller light spot, which will be received by the laser receiver (306), thereby completing the distance measurement of the target object.

[0031] In this embodiment, when the first monocular telescope (1) and the second monocular telescope (2) form a binocular telescope, the connecting member therebetween adopts a lens barrel hinge axis; when the first monocular telescope (1) and the second monocular telescope (2) form a telescope, the connecting member therebetween may be any one of a connecting sleeve and a connecting ring. Thus, through the above-mentioned detachable binocular telescope structure, multiple functions of a telescope, a monocular telescope, a binocular telescope and a mobile phone telescope can be integrated into one, so as to realize the use in different occasions.

[0032] In this embodiment, the first monocular telescope (1) and the second monocular telescope (2) each independently have a focusing device. When the first monocular telescope (1) and the second monocular telescope (2) form a binocular telescope, the first monocular telescope (1) and the second monocular telescope (2) share an external focusing structure, wherein the external focusing structure is formed by combining the two focusing devices through a connecting component. Thus, when used as binoculars, the first monocular telescope (1) and the second monocular telescope (2) share an external focusing structure. When observing targets at different distances, the shared external focusing structure changes the position of the first objective lens group (101) of the first monocular telescope (1) and the position of the second objective lens group (201) of the second monocular telescope (2), thereby adjusting the image plane of the target. The focal plane of the first monocular telescope (1) and the focal plane of the objective lens coincide with each other, so that the human eye can observe a clear image; when used as a telescope to observe a target object, the focusing devices of the first monocular telescope (1) and the second monocular telescope (2) are independent of each other; before the first objective lens group (101) of the first monocular telescope (1), the position of its image plane moves along the optical axis in the direction of the first objective lens group (101) because the lens group (4) is added; it is necessary to change the position of the first objective lens group (101) of the first monocular telescope (1) by using the focusing device of the first monocular telescope (1); when adjusted to a suitable position, the focusing device of the first monocular telescope (1) is fixed by using a buckle to eliminate the influence of the addition of the lens group (4) on the image side focal plane of the first monocular telescope (1); and the focusing of the telescopic system is achieved by using the focusing device of the second monocular telescope (2).

[0033] According to the above embodiment of the combined variable-power telescope system of the present invention, the first monocular telescope, the second monocular telescope and the lens group are included. The first monocular telescope and the second monocular telescope can be used as monoculars separately, and the first monocular telescope and the second monocular telescope can form one of binoculars or telescopes. Through the above detachable binocular telescope structure, the multiple functions of telescopes, monocular telescopes, binoculars and mobile phone telescopes can be integrated into one. In this way, when the first monocular telescope and the second monocular telescope form a telescope, the first monocular telescope, the second monocular telescope and the lens group are coaxially arranged along the observation optical path, and the second monocular telescope is arranged at the eyepiece end of the first monocular telescope, and the lens group is arranged at the objective end of the first monocular telescope. Through the arrangement of the lens group, the amount of light entering the telescopic optical system of the telescope can be increased, thereby increasing the entrance pupil diameter and exit pupil diameter of the telescopic optical system, realizing the superposition of telephoto magnifications of the telescope system, improving the resolution, and increasing the observation distance, so that the problem of difficulty and discomfort in viewing for the human eye will not occur. In addition, by adding a lens group, the superposition of telephoto magnifications of the two monocular telescopes can also be achieved to increase the observation distance.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
