Description

一种成像透镜前分离激光的共光路的测距瞄准器
本发明涉及瞄准设备技术领域，具体地，涉及一种成像透镜前分离激光的共光路的测距瞄准器。
在现有的激光测距瞄准镜中，共光路测距瞄准器属于比较高端的产品，其产品特性是激光发射、接收和成像光路是混合在一起的，这样的产品外观整洁，整体性强，结构可靠。
但是，这类产品其激光发射、接收和成像自然光光路的分离是在成像物镜的后端（产品的靠近被观察测距的物体的方向为前端），这样的结构造成发射端发出的激光会在透过成像物镜出射的同时在其后端光路内形成折射光和反射光，而这部分光会先于实际测距的反射光，通过内部光路到达接收端，形成一个近距离的高强度信号，使得近距离的测距无法实现，出现近程盲区大的问题，通常在12米内无法测距。
发明内容
本发明的目的在于提供一种成像透镜前分离激光的共光路的测距瞄准器，旨在解决现有技术中共光路瞄准镜由于在成像物镜后端分离激光反射、接收和成像自然光光路带来的近程盲区大的问题，可将最近测距距离提升到1米。
为解决上述技术问题，本发明的技术方案是：提供一种成像透镜前分离激光的共光路的测距瞄准器，其特征在于，包括：壳体、控制模块、激光发射器、激光接收器、数据显示器、激光反射自然光透射镜、凹面成像透镜和红光反射自然光透射镜，壳体设置有物像孔与观测孔，壳体形成有安装腔，控制模块、激光发射器、激光接收器、数据显示器、激光反射自然光透射镜、凹面成像透镜、红光反射自然光透射镜均安装于安装腔内，物像孔、激光反射自然光透射镜、凹面成像透镜、红光反射自然光透射镜、观测孔呈直线依次排列以形成自然光观测光路，激光发射器、激光接收器、数据显示器均与控制模块电连接，且数据显示器发射红光进行显示，激光发射器发射的激光经激光反射自然光透射镜反射后照射待测景物，待测景物反射的激光经激光反射自然光透射镜反射后由激光接收器接收，数据显示器发射的红光经红光反射自然光透射镜反射并成像于凹面成像透镜，且激光发射器发射的激光经激光反射自然光透射镜反射后的激光光路与被照射物体返回的激光经激光反射自然光透射镜反射到达接收端以及自然光观测光路共光路同轴照射。由于激光发射和接收在经过激光聚光透镜后只通过一片激光反射自然光透射的镜片，未通过成像物镜，不会出现内部折射和反射的光路，很好的避免了近程盲区大的问题。
进一步地，成像透镜前分离激光的共光路的测距瞄准器还包括激光反射镜，激光反射镜安装于安装腔内，且激光反射镜与激光反射自然光透射镜相对设置，激光发射器发射的激光经激光反射镜反射至激光反射自然光透射镜上并反射后照射待测景物，待测景物反射的激光经激光反射自然光透射镜反射至激光反射镜上并反射至激光接收器接收。
进一步地，成像透镜前分离激光的共光路的测距瞄准器还包括激光聚光透镜，激光聚光透镜安装于安装腔内，且激光聚光透镜设置于激光反射自然光透射镜与激光反射镜之间。
进一步地，凹面成像透镜为可见光透过、内凹面可反射红光的凹面成像透镜，且凹面成像透镜传播待测景物的自然光观测光路后以1：1成像。
进一步地，数据显示器发射基准点红光，该基准点红光经红光反射自然光透射镜反射并在凹面成像透镜的中心点成像为基准红点，且自然光观测光路的观测轴线穿过基准红点。
进一步地，成像透镜前分离激光的共光路的测距瞄准器还包括内置光路安装支架，内置光路安装支架安装于安装腔内，激光发射器、激光接收器、数据显示器、激光反射自然光透射镜、凹面成像透镜、红光反射自然光透射镜、激光反射镜、激光聚光透镜均固定安装于内置光路安装支架上，其中，激光发射器、激光反射镜、激光聚光透镜、激光反射自然光透射镜在内置光路安装支架内形成独立的激光发射光路，激光反射自然光透射镜、激光聚光透镜、激光反射镜、激光接收器在内置光路安装支架内形成独立的激光接收光路，数据显示器、红光反射自然光透射镜、凹面成像透镜在内置光路安装支架内形成独立的数据成像光路，激光反射自然光透射镜、凹面成像透镜、红光反射自然光透射镜在内置光路安装支架内形成独立的自然光观测光路。
进一步地，内置光路安装支架的第一端与壳体之间铰链连接，内置光路安装支架的第二端与壳体之间设置有升降调节机构。
进一步地，升降调节机构包括调节蜗杆、调节涡轮和配合螺杆，调节蜗杆、调节涡轮两者均装配于壳体上，调节蜗杆与调节涡轮相啮合，配合螺杆的第一端与内置光路安装支架固定连接，配合螺杆的第二端与调节涡轮之间螺纹连接。
进一步地，内置光路安装支架的第二端上设置有限位弹片，限位弹片预紧装配在内置光路安装支架的第二端与壳体之间，且内置光路安装支架位于升降调节机构与限位弹片之间。
进一步地，内置光路安装支架的第二端与壳体之间设置有水平调节机构。
进一步地，成像透镜前分离激光的共光路的测距瞄准器还包括第一防水玻璃和第二防水玻璃，第一防水玻璃安装于物像孔，第二防水玻璃安装于观测孔。
进一步地，壳体的外侧设置有装配槽，装配槽用于与外部装配物的装配滑轨配合安装。
本发明中，激光的发射、激光的接收在通过激光反射自然光透射镜与自然光分离后不再向激光反射自然光透射镜的后端传播，激光不会经过成像透镜而混合进入目视瞄准光路。由于设定好的反射角度，激光的发射和接收光路也不会存在互相的串扰，使共光路测距瞄准器的近程盲区（最近测距距离1米）得到极大的改善，很好的解决了现有的共光路测距瞄准器的成像物镜后端由于激光发射光路通过成像物镜后的内光路折射、反射造成的最近测距的限制大，盲区较大的问题（最近测距距离12米）。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
需要说明的是，当元件被称为“固定于”或“设置于”另一个元件，它可以直接在另一个元件上或者间接在该另一个元件上。当一个元件被称为“连接于”另一个元件，它可以是直接连接到另一个元件或者间接连接至该另一个元件上。
还需要说明的是，本实施例中的左、右、上、下等方位用语，仅是互为相对概念或是以产品的正常使用状态为参考的，而不应该认为是具有限制性的。
如图1至图10所示，本实施例的成像透镜前分离激光的共光路的测距瞄准器包括：壳体10、控制模块20、激光发射器31、激光接收器32、数据显示器33、激光反射自然光透射镜41、凹面成像透镜42和红光反射自然光透射镜43。壳体10设置有物像孔与观测孔，壳体10形成有安装腔11，控制模块20、激光发射器31、激光接收器32、数据显示器33、激光反射自然光透射镜41、凹面成像透镜42、红光反射自然光透射镜43均安装于安装腔11内，并且，物像孔、激光反射自然光透射镜41、凹面成像透镜42、红光反射自然光透射镜43、观测孔呈直线依次排列以形成自然光观测光路。激光发射器31、激光接收器32、数据显示器33均与控制模块20电连接。其中，激光发射器31发射的激光经激光反射自然光透射镜41反射后照射待测景物，待测景物反射的激光经激光反射自然光透射镜41反射后由激光接收器32接收，数据显示器33发射红光进行显示，数据显示器33发射的红光经红光反射自然光透射镜43反射并成像于凹面成像透镜42，且激光发射器31发射的激光经激光反射自然光透射镜41反射后的激光光路与自然光观测光路同轴照射。
应用本实施例的成像透镜前分离激光的共光路的测距瞄准器进行瞄准测距工作，激光发射器31所发射的激光通过激光反射自然光透射镜41反射后直接照射向待测景物，激光无需透射多余的透镜后才形成对待测景物的照射光路，然后激光由待测景物进行反射后再次经过激光反射自然光透射镜41反射由激光接收器32进行激光接收，所接收的反射激光同样无需透射多余的透镜后才被接收，因而保持了激光的传播能效而使所接收到的激光的效能较高。并且，在该成像透镜前分离激光的共光路的测距瞄准器中，使用者利用自然光对待测景物进行目视观察的过程，自然光依次透射过激光反射自然光透射镜41、凹面成像透镜42、红光反射自然光透射镜43后直接被使用者观测到，相比于现有技术中的瞄准器，自然光观测光路的光线无需经过分光棱镜、透镜等，不存在内部光路的折射、反射而影响近距离测距出现盲区大的问题，并且发射的激光或由待测景物反射回来的激光被激光反射自然光透射镜41完全反射给激光接收器32，保证了接收光路与发射光路间的隔离。而且，数据显示器33的数据通过红光反射自然光透射镜43反射后成像与凹面成像透镜42上，从而使得使用者能够简便、快速地将待测景物与所显示的数据基准进行比对，以此进行简单且精准的比对过程，使得激光照射光线与观测的自然光能够在观测过程中始终保持同轴方向，避免造成激光与目视中心偏移。在该成像透镜前分离激光的共光路的测距瞄准器中，所发射的激光与观测光线在激光反射自然光透射镜41同轴汇合之后对待测景物进行照射，并直观地在使用者观测过程中即采取数据基准与待测景物进行比对，使得观测、测距的结果更加准确。
如图7至图10所示，为了制造小巧轻便的成像透镜前分离激光的共光路的测距瞄准器，因而合理考虑并布局了壳体10的安装腔11的形成安装容积，从而将相应的零部件合理地装配布置在安装腔11内。并且，在本实施例中，成像透镜前分离激光的共光路的测距瞄准器还包括激光反射镜44，激光反射镜44安装于安装腔11内。并且，激光反射镜44与激光反射自然光透射镜41相对设置，激光发射器31发射的激光经激光反射镜44反射至激光反射自然光透射镜41上并反射后照射待测景物，这就使得激光发射器31的安装布置方式能够与自然光观测光路平行布置，即激光光线的发射方向与目视时的自然光传播方向相平行。并且，待测景物反射的激光经激光反射自然光透射镜41反射至激光反射镜44上并反射至激光接收器32接收。这样，能够更加合理地设计激光发射器31、激光接收器32等零部件在安装腔11内的布置布局，从而更加紧凑地实现成像透镜前分离激光的共光路的测距瞄准器的小型化设计。
另外，在安装腔11的安装位置优化设计过程中，如图5所示，电源电池81装配在安装腔11中，通过安装腔11的空间布置优化设计使得电源电池81避开安装腔11内其余的装配部件，并且将电源电池81与控制模块20电连接以实现电能供应。
其中，该成像透镜前分离激光的共光路的测距瞄准器中的控制模块20使用集成电路板，在集成电路板上，对应相应的应用功能设计相应的控制电路单元，例如：针对激光测距功能，设计计算控制单元，可以采用中央处理芯片（MCU、PLC等）进行装配。实际上，控制模块20所使用的集成电路板为本领域中技术成熟的现有技术，因而在此不再赘述。
优化地，本实施例的成像透镜前分离激光的共光路的测距瞄准器能够适应光线充足的环境下进行瞄准测距工作，也能够适应光线昏暗的环境下进行瞄准测距工作，为此，在控制模块20中设计了光能调节电路单元，并通过相应的调节按键进行相应调节，当光线充足时，使用者目视观测能够清楚，并且激光发射光路、激光反射光路传播效率较好，则可以通过调节按键将激光光能调低，否则就将激光光能调高。此外，在该成像透镜前分离激光的共光路的测距瞄准器上还设置有环境温度传感器，从而针对所处环境的温度进行检测，并通过数据显示器33进行显示。对此，在集成电路板上设计了显示模式转换电路单元，并通过模式切换键进行显示模式切换，即通过模式切换键能够将数据显示器33的显示内容在测距数据与温度数据之间进行切换而成像显示与凹面成像透镜42上。
在本实施例中，为了将激光发射器31发射出的激光能够更加集中地照射向待测景物，也为了将待测景物反射回来的激光更加集中地被激光接收器32进行接收，因此，本实施例的成像透镜前分离激光的共光路的测距瞄准器还包括激光聚光透镜45，激光聚光透镜45安装于安装腔11内，且激光聚光透镜45设置于激光反射自然光透射镜41与激光反射镜44之间。这样，激光发射器31发射出激光光线，并且激光光线照射到激光反射镜44上之后，由于激光反射镜44的反射过程存在一定程度的散射情况，此时，被散射的激光光线被激光聚光透镜45重新汇聚形成集中的平行激光而到达激光反射自然光透射镜41并再次反射照射向待测景物，如此，激光光线经过两次反射之后也能够保持集中地照射待测景物。当激光光线照射在待测景物上，并且激光光线被待测景物所反射之后，而待测景物所反射的激光光线也存在一定的发散情况，同样地，被待测景物反射回来的产生发散现象的激光光线也会被激光聚光透镜45聚光后再由激光反射镜44反射至激光接收器32进行接收。如此，便能够保证激光发射传播与激光接收传播的激光光线之间得到了很好的隔离，不会出现相互间的串扰，从而避免了近程干扰的，达到抑制近程盲区的问题。而且，激光的发射光路和接收光路在通过激光聚光透镜前得到了绝对的物理隔离，不会形成相互干扰。在经过激光聚光透镜后，只是经过唯一的激光反射自然光透射镜进行反射后即照射待测景物。
为了在制造、装配过程中形成模块化装配过程，从而方便工作人员进行制造加工以及装配加工，因此，该成像透镜前分离激光的共光路的测距瞄准器还包括内置光路安装支架60，内置光路安装支架60安装于安装腔11内，激光发射器31、激光接收器32、数据显示器33、激光反射自然光透射镜41、凹面成像透镜42、红光反射自然光透射镜43、激光反射镜44、激光聚光透镜45均固定安装于内置光路安装支架60上，其中，激光发射器31、激光反射镜44、激光聚光透镜45、激光反射自然光透射镜41在内置光路安装支架60内形成独立的激光发射光路，激光反射自然光透射镜41、激光聚光透镜45、激光反射镜44、激光接收器32在内置光路安装支架60内形成独立的激光接收光路（反射回的激光由激光反射自然光透射镜41反射至激光接收器32的接收光路与自然光观测光路同轴），数据显示器33、红光反射自然光透射镜43、凹面成像透镜42在内置光路安装支架60内形成独立的数据成像光路，激光反射自然光透射镜41、凹面成像透镜42、红光反射自然光透射镜43在内置光路安装支架60内形成独立的自然光观测光路。
具体地，本实施例的凹面成像透镜42为可见光透过、内凹面可反射红光的凹面成像透镜，且凹面成像透镜42传播待测景物的自然光观测光路后以1：1成像（此时使用者通过该共光路的测距瞄准器的自然光观测光路所目视观察到的待测景物的成像与使用者正常目视待测景物时候的目视成像是一致的）。并且，数据显示器33发射基准点红光，该基准点红光经红光反射自然光透射镜43反射并在凹面成像透镜的中心点成像为基准红点100，且自然光观测光路的观测轴线穿过基准红点100（在进行显示模式切换过程中，数据显示器33形成的基准红点100始终成像显示在凹面成像透镜42上）。在进行瞄准测距的过程中，使用者通过自然光观测光路对待测景物进行目视，此时，启动的数据显示器33发射的基准红点100成像显示在凹面成像透镜42上，使用者只需将该基准红点100正对待测景物，即可实现激光发射光路、激光反射光路、自然光观测光路、待测景物、使用者眼睛五者之间的同轴校对。
在本实施例中，壳体10的外侧设置有装配槽12，装配槽12用于与外部装配物的装配滑轨配合安装。使用者通过该装配槽12能够方便、快捷地将该成像透镜前分离激光的共光路的测距瞄准器进行架设，即利用相应配套的架设支架，并在架设支架上设置有与该装配槽12相互配合的装配滑轨，这样，使用者只需将该装配槽12与装配滑轨对正，然后将装配槽12嵌在装配滑轨上，然后通过如图1至图3所示的锁紧螺钉120与装配滑轨锁紧，即可完成架设工作。
在装配完成该成像透镜前分离激光的共光路的测距瞄准器之后，应用该成像透镜前分离激光的共光路的测距瞄准器进行瞄准测距的过程中，在将该成像透镜前分离激光的共光路的测距瞄准器架设完成之后，使用者目视待测景物并利用凹面成像透镜42上成像显示的基准红点100与待测景物进行基准校对，由于架设的成像透镜前分离激光的共光路的测距瞄准器与待测景物之间的角度差异而引起使用者针对不同的待测景物与基准红点100之间的基准校对存在一定的偏差，因此，内置光路安装支架60的第一端与壳体10之间铰连接，内置光路安装支架60的第二端与壳体10之间设置有升降调节机构71。具体地，升降调节机构71包括调节蜗杆711、调节涡轮712和配合螺杆713，调节蜗杆711、调节涡轮712两者均装配于壳体10上，调节蜗杆711与调节涡轮712相啮合，配合螺杆713的第一端与内置光路安装支架60固定连接，配合螺杆713的第二端与调节涡轮712之间螺纹连接。这样，当使用者目视待测景物并利用基准红点100与待测景物之间进行基准校对的过程中，使用者通过旋转调节蜗杆711，调节蜗杆711带动调节涡轮712转动，然后带动配合螺杆713上升或者下降，从而带动内置光路安装支架60整体以其第一端为支点进行上下角度调整。并且，内置光路安装支架60的第二端与壳体10之间设置有水平调节机构73。具体地，水平调节机构73包括抵顶调节螺钉731、压缩弹簧732和抵顶块733，将抵顶调节螺钉731和压缩弹簧732分别设置于内置光路安装支架60的两侧（可以在内置光路安装支架60上延伸出一个水平调节板，将抵顶调节螺钉731和压缩弹簧732分别设置于该水平调节板的两侧），使得压缩弹簧732的第一端抵接住内置光路安装支架60，然后将抵顶块733装配在压缩弹簧732与壳体10之间，使得压缩弹簧732的第二端与抵顶块733抵接，并使得抵顶块733抵接在壳体10上。在使用者需要进行水平角度调节的时候，使用者对抵顶调节螺钉731进行旋进，则抵顶调节螺钉731的端部挤压内置光路安装支架60，然后内置光路安装支架60挤压压缩弹簧732，从而实现内置光路安装支架60以其第一端为支点水平向左调节；或者，使用者对抵顶调节螺钉731进行旋出，则抵顶调节螺钉731具有脱离内置光路安装支架60的趋势，此时压缩弹簧732伸长并挤压内置光路安装支架60，从而实现内置光路安装支架60以其第一端为支点水平向右调节。
优选地，该成像透镜前分离激光的共光路的测距瞄准器的内置光路安装支架60的第二端上设置有限位弹片72，限位弹片72预紧装配在内置光路安装支架60的第二端与壳体10之间，且内置光路安装支架60位于升降调节机构71与限位弹片72之间。这样，在对内置光路安装支架60进行上下角度调节的过程中，限位弹片72始终预紧压缩在内置光路安装支架60与壳体10之间，从而将内置光路安装支架60相对于壳体10的相对位置稳定住，使得内置光路安装支架60在上下调节、水平调节的过程中均不会发生随意偏移错位的问题，保持内置光路安装支架60的稳定性。
如图1、图2、图4、图7至图10所示，本实施例的成像透镜前分离激光的共光路的测距瞄准器还包括第一防水玻璃51和第二防水玻璃52，第一防水玻璃51安装于物像孔，第二防水玻璃52安装于观测孔。利用第一防水玻璃51、第二防水玻璃52安装在壳体10的物像孔和观测孔上以实现密封防水，并且在设计安装调节蜗杆711、抵顶调节螺钉731时候也进行密封防水设计，这样，当使用者在户外并处于阴雨天气时候，雨水无法进入壳体10内部对控制模块20造成损坏，使用者仍能够对待测景物进行瞄准测距工作。另外，第一防水玻璃51、第二防水玻璃52也能够放置灰尘杂物进入到安装腔11中，从而达到防止灰尘杂物对安装腔11内的控制模块20、光学镜片等造成污染，保证该成像透镜前分离激光的共光路的测距瞄准器的内部清洁。
具体地，激光发射器31所发射的激光的波段为905nm，数据显示器33发射的显示红光的波长为650nm。如图7和图8所示，自然光透过第一防水玻璃51、激光反射自然光透射镜41、凹面成像透镜42、红光反射自然光透射镜43、第二防水玻璃52形成自然光观测光路。启动该成像透镜前分离激光的共光路的测距瞄准器之后，数据显示器33发出的波长为650nm红光经红光反射自然光透射镜43反射至凹面成像透镜42上进行成像显示。如图7和图9所示，激光发射器31发射出的激光光线照射向激光反射镜44，然后通过激光发射聚光透镜451进行汇聚集中形成平行照射的激光照射至激光反射自然光透射镜41上，汇聚集中后的激光经激光反射自然光透射镜41反射后照射至待测景物。相应地，如图7和图10所示，激光经待测景物反射至激光反射自然光透射镜41上，激光反射自然光透射镜41反射的有待测景物反射回来的激光则通过激光接收聚光透镜452进行汇聚集中照射向激光反射镜44（即激光聚光透镜45包括激光发射聚光透镜451和激光接收聚光透镜452），从而将激光反射至激光接收器32进行激光接收。在该成像透镜前分离激光的共光路的测距瞄准器中，将上述四个光路进行复合，即为该成像透镜前分离激光的共光路的测距瞄准器中的实际工作过程的光路构成。
在本实施例中，激光反射自然光透射镜41在自然光和激光原始状态未发生改变时将自然光和激光分离，分离后的自然光进入后端的光学成像系统组成部分（即凹面成像透镜42、红光反射自然光透射镜43、第二防水玻璃52）。激光由于是通过反射光路，其收发能量都得到最大的保证，由于激光反射自然光透射镜41的镀膜特性使激光可以从自然光得到充分的分离，使光学仪器中激光的成分降到最低，从而保证使用者得到一个更安全的光学使用环境。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
