目鏡組11、31、平板玻璃12、32、稜鏡組13、33、調焦透鏡14、34及物鏡組16、36組成雙筒望遠測距儀100之望遠系統。使用者之雙眼可透過目鏡組11、31觀看遠方一被測物(未圖示),目鏡組11與目鏡組31之間距可經由中心轉軸50調整,以適合使用者之雙眼間距。平板玻璃12、32標示有準心121、321(如第1B圖所示)以供瞄準被測物。調焦透鏡14、34可被調整以改變其與物鏡組16、36之間距,使得被測物能清晰成像。 The eyepiece groups 11, 31, the flat glass 12, 32, the cymbal groups 13, 33, the focus lenses 14, 34 and the objective lens groups 16, 36 constitute a telephoto system of the binocular telephoto rangefinder 100. The user's eyes can view a distant object (not shown) through the eyepiece groups 11, 31, and the distance between the eyepiece group 11 and the eyepiece group 31 can be adjusted via the center shaft 50 to suit the distance between the eyes of the user. The plate glass 12, 32 is marked with a centering 121, 321 (as shown in Figure 1B) for aiming at the object under test. The focus lens 14, 34 can be adjusted to change its distance from the objective lens group 16, 36 so that the object to be measured can be clearly imaged.
半導體雷射15、稜鏡組13、調焦透鏡14及物鏡組16組成雙筒望遠測距儀100之發射系統。崩潰光二極體(APD)35、稜鏡組33、調焦透鏡34及物鏡組36組成雙筒望遠測距儀100之接收系統。當使用者欲測距時,使用者之雙眼先透過目鏡組11與目鏡組31觀看遠方被測物(未圖示),再將平板玻璃12、32所標示的準心121、321(如第1B圖所示)對準被測物,以完成被測物瞄準,接著半導體雷射15可發出一紅外光,依序通過稜鏡組13、調焦透鏡14、物鏡組16,最後射向被測物,被測物可將入射的紅外光反射,使反射的紅外光射回雙筒望遠測距儀100,射回雙筒望遠測距儀100的紅外光依序通過物鏡組36、調焦透鏡34、稜鏡組33,最後由崩潰光二極體(APD)35接收,再經後續的資料處理即可將被測物距離算出。 The semiconductor laser 15, the cymbal group 13, the focus lens 14, and the objective lens group 16 constitute a launch system of the binocular telemetry range finder 100.

The measured object, the measured object can reflect the incident infrared light, so that the reflected infrared light is returned to the binocular telescope range finder 100, and the infrared light that is returned to the binocular telescope range finder 100 sequentially passes through the objective lens group 36, and is adjusted. The focal lens 34 and the cymbal group 33 are finally received by the colliding light diode (APD) 35, and the distance of the measured object can be calculated by subsequent data processing.
以下將先針對稜鏡組之構造進一步詳細介紹,再說明可見光及紅外光通過稜鏡組時之光學路徑。 In the following, the structure of the 稜鏡 group will be further described in detail, and the optical path of visible light and infrared light passing through the 稜鏡 group will be described.
請同時參閱第2A圖及第2B圖。第2A圖係第1A圖之稜鏡 組的可見光光路示意圖,第2B圖係第1A圖之稜鏡組的紅外光光路示意圖。如第2A圖所示,稜鏡組33包括一第一稜鏡331、一第二稜鏡333、一第三稜鏡335及一光學多層膜337。第一稜鏡331包括一第一面3311、一第二面3312及一第三面3313。第二稜鏡333包括一第四面3331、一第五面3332及一第六面3333。第三稜鏡335包括一第七面3351、一第八面3352、一第一屋頂面(Roof Surface)3353及一第二屋頂面(Roof Surface)3354,第一屋頂面(Roof Surface)3353及第二屋頂面(Roof Surface)3354交會於屋脊3355。第七面3351面向第二面3312,第五面3332面向第三面3313。光學多層膜337設置於第三面3313與第五面3332之間,光學多層膜337只允許紅外光通過,可見光將被反射。第一稜鏡331之第三面3313與第二稜鏡333之第五面3332膠合。 Please also refer to Figures 2A and 2B. Figure 2A is the top of Figure 1A A schematic diagram of the visible light path of the group, and FIG. 2B is a schematic diagram of the infrared light path of the group 第1A. As shown in FIG. 2A, the crucible group 33 includes a first crucible 331, a second crucible 333, a third crucible 335, and an optical multilayer film 337. The first side 331 includes a first surface 3311, a second surface 3312, and a third surface 3313. The second port 333 includes a fourth surface 3331, a fifth surface 3332, and a sixth surface 3333. The third crucible 335 includes a seventh surface 3351, an eighth surface 3352, a first roof surface 3353 and a second roof surface 3354, a first roof surface 3353 and The second Roof Surface 3354 meets at the ridge 3355. The seventh surface 3351 faces the second surface 3312, and the fifth surface 3332 faces the third surface 3313. The optical multilayer film 337 is disposed between the third surface 3313 and the fifth surface 3332. The optical multilayer film 337 allows only infrared light to pass therethrough, and the visible light will be reflected. The third face 3313 of the first weir 331 is glued to the fifth face 3332 of the second weir 333.
當一可見光38入射第一稜鏡331後,將直接穿透第一面3311射向第二面3312,射向第二面3312的可見光38將發生全反射,使得可見光38改變行進方向射向第三面3313及光學多層膜337,因為光學多層膜337只允許紅外光通過,可見光將被反射,所以可見光38將被反射改變行進方向射向第二面3312,且由第二面3312射出第一稜鏡331再射向第三稜鏡335,射向第三稜鏡335的可見光38將直接穿透第七面3351,接著可見光38將於第八面3352、屋脊3355及第七面3351發生全反射改變行進方向,最後由第八面3352射出第三稜鏡335。可見光38入射稜鏡組33之方向與射出稜鏡組33之方向相同且在同一軸線上。 When a visible light 38 is incident on the first ridge 331, the first surface 3311 is directly incident on the second surface 3312, and the visible light 38 directed to the second surface 3312 is totally reflected, so that the visible light 38 changes direction of travel. The three sides 3313 and the optical multilayer film 337, because the optical multilayer film 337 only allows infrared light to pass, the visible light will be reflected, so the visible light 38 will be reflected by the reflection changing direction of travel toward the second surface 3312, and the second surface 3312 is emitted first The 稜鏡331 is again directed toward the third 稜鏡335, and the visible light 38 directed at the third 稜鏡335 will directly penetrate the seventh surface 3351, and then the visible light 38 will be generated on the eighth surface 3352, the ridge 3355 and the seventh surface 3351. The reflection changes the direction of travel, and finally the third aperture 335 is emitted by the eighth surface 3352. The direction in which the visible light 38 is incident on the crucible group 33 is the same as the direction of the exit pupil group 33 and on the same axis.
請參考第2B圖,當一紅外光39入射第一稜鏡331後,將直接穿透第一面3311射向第二面3312,射向第二面3312的紅外光39發生全反射,使得紅外光39改變行進方向射向第三面3313及光學多層膜337,因為光學多層膜337只允許紅外光通過,所以紅外光39將直接穿透第三面 3313及光學多層膜337射入第二稜鏡333,射入第二稜鏡333的紅外光39將直將穿透第五面3332,接著射向第六面3333,再經第六面3333全反射改變行進方向,最後由第四面3331射出第二稜鏡333。紅外光39入射稜鏡組33之方向與射出稜鏡組33之方向相反且不在同一軸線上。 Referring to FIG. 2B, when an infrared light 39 is incident on the first ridge 331, the first surface 3311 directly penetrates the second surface 3312, and the infrared light 39 that is incident on the second surface 3312 is totally reflected, so that the infrared The light 39 changes the traveling direction to the third surface 3313 and the optical multilayer film 337. Since the optical multilayer film 337 only allows infrared light to pass, the infrared light 39 will directly penetrate the third surface. 3313 and the optical multilayer film 337 are incident on the second crucible 333, and the infrared light 39 incident on the second crucible 333 will directly penetrate the fifth surface 3332, then the sixth surface 3333, and then the sixth surface 3333. The reflection changes the direction of travel, and finally the second surface 333 is emitted by the fourth surface 3331. The direction in which the infrared light 39 is incident on the crucible group 33 is opposite to the direction of the exit pupil group 33 and is not on the same axis.
本實施例中的第三稜鏡335可為屋脊稜鏡(Roof Prism),例如別漢稜鏡(Pechan Prism)。 The third crucible 335 in this embodiment may be Roof Prism, such as Pechan Prism.
綜上所述,當可見光38及紅外光39同時由第一面3311入射稜鏡組33後,可見光38及紅外光39將被分光,朝不同方向前進,可見光38將從第八面3352射出稜鏡組33,且其行進方向沒有改變,紅外光39將從第四面3331射出稜鏡組33,且改變其行進方向往反方向前進。也可以將紅外光39由第四面3331射入稜鏡組33,最後由第一面3311射出稜鏡組33,且改變其行進方向往反方向前進,可見光38仍然從第一面3311入射稜鏡組33,最後從第八面3352射出稜鏡組33,且其行進方向沒有改變。 In summary, when the visible light 38 and the infrared light 39 are simultaneously incident on the first group 3311, the visible light 38 and the infrared light 39 will be split and proceed in different directions, and the visible light 38 will be emitted from the eighth surface 3352. The mirror group 33, and its traveling direction is not changed, and the infrared light 39 will exit the stack 33 from the fourth face 3331 and change its traveling direction to advance in the opposite direction. It is also possible to inject the infrared light 39 from the fourth surface 3331 into the crucible group 33, and finally to eject the crucible group 33 from the first surface 3311, and change its traveling direction to advance in the opposite direction, and the visible light 38 still enters the edge from the first surface 3311. The mirror group 33 finally emits the cymbal group 33 from the eighth surface 3352, and its traveling direction is not changed.
本實施例中,稜鏡組13與稜鏡組33相同,只是擺放方式不同,使得稜鏡組13與稜鏡組33之外形以中心轉軸50為對稱軸互相對稱,所以可見光及紅外光通過稜鏡組13時之光學路徑與通過稜鏡組33時之光學路徑相似,因此省略其說明。 In this embodiment, the cymbal group 13 is the same as the cymbal group 33 except that the cymbal group 13 and the cymbal group 33 are symmetrical with each other with the central axis of rotation 50 as an axis of symmetry, so visible light and infrared light pass through. The optical path of the group 13 is similar to the optical path when passing through the group 33, and therefore the description thereof will be omitted.
請參閱第3圖,第3圖係第1A圖之接收鏡筒的可見光光路及紅外光光路示意圖。被測物可將入射的可見光、紅外光反射,使反射的可見光、紅外光射向雙筒望遠測距儀。當由被測物所反射的一可見光38及一紅外光39射向接收鏡筒30時,可見光38及紅外光39將沿著一第一軸41先通過物鏡組36及調焦透鏡34,再由第一面3311入射稜鏡組33。紅外光39將被第二面3312全反射改變行進方向,接著穿透第三面3313、光學多層膜337及第五面3332,再經第六面3333全反射,由第四面3331射出稜 鏡組33,最後沿著一第二軸42入射崩潰光二極體(APD)35。另一方面,可見光38被第二面3312全反射後將再被光學多層膜337反射,由第二面3312射出第一稜鏡331,再射向第三稜鏡335,射向第三稜鏡335的可見光38將直接穿透第七面3351,接著可見光38將分別於第八面3352、屋脊3355及第七面3351發生全反射改變行進方向,最後由第八面3352射出第三稜鏡335,再沿著第一軸41通過平板玻璃32、目鏡組31,使用者可通過目鏡組31觀看被測物影像。 Please refer to FIG. 3, which is a schematic diagram of the visible light path and the infrared light path of the receiving lens barrel of FIG. 1A. The object to be measured can reflect incident visible light and infrared light, and the reflected visible light and infrared light are directed to the binocular telephoto range finder. When a visible light 38 and an infrared light 39 reflected by the measured object are incident on the receiving lens barrel 30, the visible light 38 and the infrared light 39 will first pass through the objective lens group 36 and the focusing lens 34 along a first axis 41, and then The stack 33 is incident on the first face 3311. The infrared light 39 will be totally reflected by the second surface 3312 to change the traveling direction, and then penetrate the third surface 3313, the optical multilayer film 337 and the fifth surface 3332, and then totally reflected by the sixth surface 3333, and the fourth surface 3331 is emitted from the edge. The mirror group 33 finally enters the crash light diode (APD) 35 along a second axis 42. On the other hand, the visible light 38 is totally reflected by the second surface 3312 and then reflected by the optical multilayer film 337. The second surface 3312 emits the first flaw 331 and is directed to the third crucible 335 to be directed to the third crucible. The visible light 38 of 335 will directly penetrate the seventh surface 3351, and then the visible light 38 will be totally reflected on the eighth surface 3352, the ridge 3355 and the seventh surface 3351 to change the traveling direction, and finally the third surface 335 is emitted by the eighth surface 3352. Then, the flat glass 32 and the eyepiece group 31 are passed along the first axis 41, and the user can view the image of the object through the eyepiece group 31.
至於可見光及紅外光通過第1A圖之發射鏡筒10的光路與通過接收鏡筒30的光路近似,因此省略其圖示,僅由以下文字簡單說明。請參考第1A圖,半導體雷射15發出的紅外光先由第四面入射稜鏡組13,再由第一面射出稜鏡組13,接著依序通過調焦透鏡14、物鏡組16,最後射向被測物,被測物再將入射的紅外光反射回雙筒望遠測距儀100由接收鏡筒30接收。當由被測物反射的可見光射向發射鏡筒10時,可見光將先通過物鏡組16及調焦透鏡14,由第一面入射稜鏡組13,再由第八面射出稜鏡組13,接著依序通過平板玻璃12、目鏡組11,使用者可通過目鏡組11觀看被測物影像。 Since the optical path of the visible light beam and the infrared light passing through the transmitting lens barrel 10 of FIG. 1A is similar to the light path passing through the receiving lens barrel 30, the illustration thereof is omitted, and only the following text will be briefly described. Referring to FIG. 1A, the infrared light emitted by the semiconductor laser 15 is first incident on the 稜鏡 group 13 from the fourth surface, and then the 稜鏡 group 13 is emitted from the first surface, and then sequentially passed through the focus lens 14, the objective lens group 16, and finally The object is directed to the object to be tested, and the object to be detected reflects the incident infrared light back to the binocular telescope 100 to be received by the receiving barrel 30. When the visible light reflected by the measured object is directed to the transmitting barrel 10, the visible light will first pass through the objective lens group 16 and the focusing lens 14, and the first surface is incident on the group 13 and then the eighth surface is emitted from the group 13. Then, the plate glass 12 and the eyepiece group 11 are sequentially passed through, and the user can view the image of the object to be measured through the eyepiece group 11.
由第3圖可知,可見光之光路通過平板玻璃之準心(請參考第1B圖)與目鏡組到達使用者眼睛(未圖示),即被測物(未圖示)、準心及使用者眼睛係位於同一軸線上,所以只需將準心(請參考第1B圖)對準被測物(未圖示),不需再調整準心所瞄準位置,即可瞄準被測物。 As can be seen from Fig. 3, the visible light path passes through the center of the flat glass (see Fig. 1B) and the eyepiece group reaches the user's eyes (not shown), that is, the object to be tested (not shown), the center of gravity, and the user. The eyes are on the same axis, so just aim the alignment (see Figure 1B) against the object to be tested (not shown) and aim at the object without adjusting the aiming position.
上述實施例中,也可將平板玻璃12、32改換為穿透式液晶顯示器(LCD)或有機發光二極體(OLED),此時雙筒望遠測距儀之剖面示意圖、可見光光路及紅外光光路示意圖與上述實施例中的第1A圖與第3圖相似,因此省略其圖例,將平板玻璃12、32改換為穿透式液晶顯示器(LCD) 或有機發光二極體(OLED)與上述實施例不同處,主要在於穿透式液晶顯示器(LCD)或有機發光二極體(OLED)之觀測畫面除了準心521、721(如第4圖所示)外,還增加了測距值522、722(如第4圖所示)。 In the above embodiment, the flat glass 12, 32 can also be changed into a transmissive liquid crystal display (LCD) or an organic light emitting diode (OLED). At this time, the cross-sectional view of the binocular telephoto rangefinder, the visible light path and the infrared light The optical path diagram is similar to the first embodiment and the third embodiment in the above embodiment, so the illustration is omitted, and the flat glass 12, 32 is changed to a transmissive liquid crystal display (LCD). Or the difference between the organic light emitting diode (OLED) and the above embodiment, mainly in the observation screen of the transmissive liquid crystal display (LCD) or the organic light emitting diode (OLED), except for the alignments 521 and 721 (as shown in FIG. 4) In addition to the display, the distance measurement values 522, 722 are also added (as shown in Fig. 4).
