按，雷射測距儀之光學系統通常包含有一雷射發射系統、一雷射接收 系統及-望遠錄，其中雷射發射統係藉由1射發㈣朝—受測目標 物發射-雷射絲，該簡絲_目標物岐射之後雜驗接收系統 之雷射接收騎接收’通過程式計算便可得出該雷射測距儀與受測目標物 之間的距離。望遠系統係可供使用者畔目標物，其通常包含有對物鏡組、 接眼鏡組及位機兩聽之間_鏡組，，於實際使㈣，若雷射測距 儀之上述各线雜關讀光恤再輯各自所純辨制，則不但 會造成該雷射測距儀之體積龐大，亦會使得測距結果不準確。 爲克服採壯述三侧立祕存在之缺點，轉提出了—種將其中之 兩系統予以適度合併的解決方案。如第―圖所示，刻知雷射測距儀之光 學系統9包含有-望遠/雷射發射系統9G及—雷射接收系統Μ，其中雷射 接收系統91包含有-第-接收透鏡92、—第二接收_3及—雷射接收 器94 ;望遠/雷射發射系統⑽係由雷射發射系統與望遠系統整合而成，其 包含-對物鏡組95、-稜鏡組96、—雷射發㈣97、—發射透鏡98及一 接眼鏡組99。稜鏡組96係由—前稜鏡，、—後稜鏡_及一輔助稜鏡 組成。利_鏡組96之折射與反射魏，可錢得在減鏡組邪之前 201109626 形成-混合光路’既可使得望雜測用之可見光束通過，又可使得測距用 之雷射光束通過，藉此減小雷射測距儀的體積。 詳細而言，上述習知雷酬距儀之光學綠9的光路組成包含有位於 望遠光軸A轴的-望达或觀測光路、位於β抽的一雷射接收光路u以及 同時位於C軸與Α軸的-雷射發射光路12，其中Β軸係與Α抽平行，c軸 則與A軸基本垂直。雷射發射光路12係藉由雷射發射器發射出一雷射 光束，該雷射光束沿c軸依序經過發射透鏡98的准直及辅助稜鏡963與前 棱鏡961的折射後導入α軸的望遠光路中，再經由對物鏡組准直射 出至受測目標物。由受測目標物反射回的該雷射光束隨後導入至B軸的雷 射接收光路1卜依序經由第一、第二接收透鏡92、⑽後被雷射接收器⑽ 所接收，以計算出雷射測距儀與受測目標物之間的距離。在望遠光路10中， 來自受測目標物表面的可見光束係沿A轴進入對物鏡組95，經由前棱鏡961 與後稜鏡962的折射與反射後，再經由接眼鏡組⑽透出而聚焦成像於使用 者的眼睛，以供使用者望遠並瞄準受測目標物。 由上述可知，於該習知雷射測距儀的光學系統9 +，雷射接收系統91 係爲一獨立系統’其光路11單獨位於與望遠光軸A軸平行的β軸上，而雷 射發射系統與望縣統則係整合成-望遠/雷射發射系統9G，該兩系統之 光路12、1〇係於A軸上部分重合並共用對物鏡組95與棱鏡組％的前棱鏡 961以達成減小雷射酿儀體積之目❾。由於雷射發射系統與望遠系統係

皆有較大的限制’致使該習知雷射測距儀的外觀σ徑與整體體積皆相當 大’已無法滿足當前電子消費產品日趨輕、薄、短、小之發展趨勢。 再有’採用上述光學线9的習知雷射測距儀的外轉構僅可設計爲 雙筒或三筒架構，除體積較大、攜帶不便之缺點外，亦需另外設置一眼幅 調整機構以使測距儀之眼幅與使用者之目距保持一致，從而使該習知雷射 #舰儀的機構更爲複雜’體積更顯龐大。相對雙筒或三筒架構之雷射測距 儀而言，單筒架構體積較小、攜帶方便，適合於手持望遠而更符合當前輕、 薄、短、小之消費需求，且單筒架構之雷射測距儀的使用場合更爲廣泛， 除可如雙筒或三筒架構般作爲具有測距功能的望遠鏡使用外，其亦可作爲 具有測距功能的猫準器用於獵搶等需要使用晦準器的器具上。 因此’如何設料-㈣於單㈣構之魏測距顧㈣光學系統， 鲁使該補雷射舰儀具有體積較小、攜帶方便、應赌泛等優點而又能保

laser receiving system and a telephoto system, wherein the laser emission system is transmitted by a (four)-to-measure target-laser The wire, the silk _ target, the laser receiving the receiving system after the laser receiving the receiving system, the distance between the laser range finder and the object to be tested can be obtained by program calculation. The telescope system is for the user to target the object, which usually includes the pair of mirrors, the pair of glasses and the position of the camera, and the actual group (4), if the above-mentioned lines of the laser range finder are miscellaneous The purely discerning of the reading of the shirts will not only cause the size of the laser rangefinder, but also make the ranging results inaccurate. In order to overcome the shortcomings of the three sides of the secret, we proposed a solution to moderately combine the two systems. As shown in the figure, the optical system 9 of the laser range finder includes a telephoto/laser transmitting system 9G and a laser receiving system Μ, wherein the laser receiving system 91 includes a -receiving lens 92. , the second receiving _3 and the laser receiver 94; the telephoto/laser transmitting system (10) is formed by integrating the laser emitting system and the telescope system, and includes the pair of objective lens sets 95, - 稜鏡 group 96, The laser hair (four) 97, the emitting lens 98 and an eyeglass group 99. The 稜鏡 group 96 consists of - front 稜鏡, _ 稜鏡 _ and one auxiliary 稜鏡. Lee _ mirror group 96 refraction and reflection Wei, can be money before the reduction of the group evils 201109626 formation - mixed light path 'can not only make the visible beam through the miscellaneous measurement, but also make the laser beam for distance measurement, Thereby reducing the volume of the laser rangefinder. In detail, the optical path composition of the optical green 9 of the above-mentioned conventional lightning distance meter includes a -view or observation optical path located on the A-axis of the telephoto optical axis, a laser receiving optical path u located in the β pumping, and a C-axis simultaneously The x-axis-laser emission path 12, wherein the x-axis is parallel to the pumping, and the c-axis is substantially perpendicular to the A-axis. The laser emitting light path 12 emits a laser beam by a laser emitter, and the laser beam passes through the collimation of the emitting lens 98 along the c-axis and the auxiliary 稜鏡963 and the front prism 961 are refracted and then introduced into the α-axis. In the long-distance light path, the target lens is collimated directly to the object to be tested. The laser beam reflected back from the object to be measured is then introduced into the B-axis laser receiving optical path 1 and sequentially received by the laser receiver (10) via the first and second receiving lenses 92, (10) to calculate The distance between the laser rangefinder and the target being measured. In the telephoto path 10, the visible beam from the surface of the object to be measured enters the pair of objective lenses 95 along the A axis, is refracted and reflected by the front prism 961 and the rear ridge 962, and then is focused through the lens set (10). It is imaged on the user's eyes for the user to look far and aim at the target being measured. It can be seen from the above that in the optical system 9 + of the conventional laser range finder, the laser receiving system 91 is an independent system whose optical path 11 is separately located on the β axis parallel to the A axis of the telephoto optical axis, and the laser The launching system and the Wangxian system are integrated into a telescope/laser launching system 9G. The optical paths 12 and 1 of the two systems are partially combined on the A-axis and merged with the front prism 961 of the objective lens group 95 and the prism group %. Achieved the goal of reducing the volume of the laser brewer. Since the laser emitting system shares the object and 95 with the telescope system, the design aperture of the objective lens group 95 is usually large. In addition, the long-range ranging function for the market, the first reception of the laser receiving button on the B-axis is '^ again. The ten caliber is also very large' to ensure that more laser light energy is received. Therefore, for the conventional laser range finder having the optical system 9 of the telephoto/laser emission system 90, 201109626 is to achieve a longer distance ranging function, which is committed to the objective lens group 95 and the first receiving lens. The caliber design has a large limit 'so that the appearance of the conventional laser range finder is very large in both the σ diameter and the overall volume', which cannot meet the trend of the current light, thin, short and small electronic consumer products. Furthermore, the external rotation structure of the conventional laser range finder using the above optical line 9 can only be designed as a double cylinder or a three cylinder structure. In addition to the disadvantages of large volume and inconvenient carrying, an additional eye adjustment mechanism is also required. In order to make the eyepiece of the rangefinder consistent with the eye distance of the user, the mechanism of the conventional laser instrument is more complicated, and the volume is more bulky. Compared with the laser range finder of the double or triple cylinder structure, the single cylinder structure is small in size and convenient to carry, and is suitable for the handheld telescope and more suitable for the current light, thin, short and small consumer demand, and the single cylinder structure The laser range finder is used in a wider range of applications. It can be used as a telescope with ranging function, such as a double-tube or a three-barrel structure. It can also be used as a standard device for ranging and hunting. On the appliance of the aligner. Therefore, 'how to set up materials-(four) in the single (four) structure of the Wei distance measurement (four) optical system, Lu made the supplemental laser ship instrument has the advantages of small size, easy to carry, should be gambling, and can maintain good optical ranging Performance has become a common appeal of the industry.

In detail, the optical system of the single-tube laser range finder of the present invention comprises a laser emitting system 2 of the military alone (10) and A telephoto/laser receiving system 3 located on the A-axis and the C-axis, wherein the b-axis is parallel to the A-axis and the C-axis is substantially perpendicular to the A-axis. The laser-emitting system 2 follows the B-axis from the object end to the eye end. The sequence includes an emission lens 21 and a laser emitter 22' and includes at least the laser emitter 22. The laser emitter 22 emits a laser beam with a specific wavelength and is invisible toward the object to be measured. The laser beam is collimated along the B axis by the emission lens 21 and then emitted to the object to be tested. Looking forward to 201109626 Far/Ray Shooting "The 3 series of the Yuan or Guanxian County 4 and the energy fox secret 5 integration. T system (4) her _ to pick up the order of the Qing, the telescope prism (four) and the eyelids 42, which ride the mirror 纟 丝 _ from The visible light beam of the object and the laser beam reflected back by the object are connected to the eyeglass group 42 for the user to view the image of the object to be tested. The telephoto group 41 is composed of a front 411 and a rear prism 412. The composition is used to conduct the visible light beam to the connection _ and 42. The laser receiving system 5 includes the receiving mirror P on the plucked axis, the objective lens group 4G and the spectroscopic reading 51, and the g and 麟 g axis on the secret (four) mirror Μ and thunder The hair emitters 53 are disposed between the objective lens group 4A and the telephoto prism group, and the receiving lens 52 is located below the knife light 51 and between the beam splitting element 5i and the laser emitter. In the present embodiment, the beam splitter is formed by bonding two isosceles right angles of a conventional light splitting prism, and has a recording film surface 5ΐ obliquely disposed on the eight axes for reflecting the laser light. And penetrate visible light. The receiving lens 52 is of a very small size - a filter #, such as a black glass sheet, having a film layer thereon for total reflection of visible light and high penetration of laser light. In the following, a detailed description will be given of each of the light path clamps of the (four) single-chip optical optical lens (as indicated by the arrow in the second figure of Lu). The laser emitting light path 6 corresponding to the laser emitting system 2 is emitted by the laser emitter 22 toward the object to be tested by a laser beam having a specific wavelength and is invisible, and the laser beam is invisible. The beam is collimated along the B axis via the emission lens 22 and is emitted to the object under test. The laser beam reflected back by the object to be measured is then introduced to the A-axis to form a laser receiving optical path 7 corresponding to the laser receiving system 5. In the laser receiving optical path 7, the laser beam reflected back by the object passes through the pair of objective lens groups 40 along the A axis, enters the beam splitting element 51, is reflected by the plated surface 511 of the beam splitting element 51, and is introduced to the substantially A-axis. The vertical C-axis is filtered by the receiving lens 52 on the c-axis and then received by 201109626 and (4) 53 to calculate the distance between the laser range finder and the object under test. In the same way, in the telephoto light path 8 corresponding to the telescope system 4, the visible light beam from the surface of the object to be measured is Α axis into the eight pairs of objective lens groups ♦ the visible wire passes through the surface of the beam splitting tree μ Advance-walk into the telescope group 41' by the telescope group's fiber 4Π and the posterior 稜鏡4丨2 clear, and finally the 12-shot _focus imaged in the user's eyes for the user to look far According to the above, the optical system of the single-tube laser range finder of the present invention and the silk system 9 of the conventional double-tube or three-tube laser range finder of the first-line display are disclosed. It is: the laser emission system 2 of the Department of Science and Technology is located on the β pumping parallel to the telescope optical axis of the laser rangefinder, which is an independent optical system, and the telescope system 4 and the laser receiving button 5 _ integration It becomes a telephoto/laser receiving system 3 and is located on the x-axis and the C-axis. The telescope system 4 and the laser receiving system 5 are partially overlapped on the A-axis and formed before the telephoto (four)-mixed optical path and shared. For the objective lens group 40, this can make the visible light beam from the measured _ table _ 远远 (4) pass 'again The laser beam for distance measurement is passed through. The invention is integrated into the same __ optical system, the collision system 4 and the laser receiving system, and the system 5 is integrated into the same system. A telephoto/laser receiving system 3 can greatly reduce the volume of the laser range finder and is suitable for a laser range finder in a single cylinder form. In detail, 'the laser receiving system 5 of the optical system 1 of the present invention The objective lens group 40 of the telephoto system 4 is shared, so that it is no longer necessary to design the conventional first receiving lens 92 having a larger diameter as shown in the first figure, but only on the optical axis A in the pair of objective lens groups 40 and telescope edges. A beam splitting element 51 is disposed between the mirror groups 41. The filtering function of the laser receiving system 5 is replaced by a small filter 52. Although the optical system 1 of the present invention still needs to be disposed parallel to the optical axis A. The laser emits an optical axis b, but the laser emission 201109626 The diameter of the emission lens 21 of the system 2 is very small relative to the conventional first receiving lens 92. Therefore, the laser range finder using the optical system i of the present invention The overall volume will be greatly reduced to meet current light, thin, short, and small The consumer demand is comparable to the dual-tube or three-barrel laser rangefinder using the conventional optical system 9 shown in the figure, which can reduce the volume by about half and can be applied to the laser measurement in the single cylinder form. The optical system of the present invention does not detract from the optical ranging performance of the laser range finder, and the actual optical and ranging functions can still reach the same size of the double cylinder or the three cylinders. The performance requirements of the laser range finder are extremely high industrial utilization. In addition, the optical group i of the present invention is composed of only the front 稜鏡411 and the rear prism 412, and she is in Lingwei, _ In the case of the syllabus of the syllabus, the design is more simplified. It can be understood that the optical system i of the single-tube laser range finder of the present invention is not limited to the second figure, and is implemented. The example form 'may have other equivalent variations. For example, the splitter 51 of the laser receiving system 5 can also be arranged on the A-axis of the beam splitter, and the surface of the face mirror group 40 can be woven by means of plating, silk or coating. In order to achieve the reflection of the laser first and penetrate the visible light, the volume of the optical plus single-tube laser range finder of the invention can be further reduced, and the domain can be further reduced.
