Description

一种辅助光学系统 技术领域
本发明涉及一种辅助光学系统，特别涉及一种用于枪械上瞄准镜的辅助光学系统。
 背景技术
瞄准镜，尤其是传统的望远镜式瞄准镜自发明以来就因为它可以清晰准确地命中目标在比赛、狩猎和军事活动中得到广泛运用。随着科技的进步，各种通过感光芯片成像数码瞄准镜随之而出现，如夜视，热成像等通过感光芯片成像的数码瞄准镜，和这些数码瞄准镜相比，传统的望远镜式瞄准镜在可靠性，稳定性，准确性和远距离的清晰度方面是拥有绝对优势的，可是随着时代的进步，它在特殊环境条件应用方面比如低照度条件下使用等也有着明显的劣势。
 技术问题
为了能够在低照度条件下如夜晚时实现瞄准功能，通常夜视，热成像等通过感光芯片成像的数码瞄准镜是首选，将传统的望远镜式瞄准镜更换成数码瞄准镜需要将瞄准镜从枪上面拆下来，安装上数码瞄准镜，再对安装上的数码瞄准镜进行归零，归零是指在安装光学瞄准具时，由于弹头飞行的过程是抛物线轨迹，而瞄准镜的瞄准线是直线的特性，使发射的弹头在特定的距离时能准确地命中瞄准点（通常是瞄准镜十字中心点），在这个距离上弹头轨迹和瞄准点重合的点称作归零点，光线经过瞄准镜镜头到达目标瞄准点的直线称作瞄准线。由于归零需要在特定的距离让子弹命中瞄准点，射手需要准确测量出归零距离，然后在这个距离上放置枪靶，确保环境无风，且要把枪放在稳定架上或射击枕上，不断调整瞄准镜进行射击才能实现，它是一个繁杂的过程，因为归零时如果有小偏差，射击时就会有大偏差，而且不是所有的环境里都可以通过射击来归零的，比如有风或战场或狩猎时需要保持安静的时候，因此归零是射手竭力避免的程序。一旦在某一距离归零完毕，在其它距离准确地命中目标，需要根据子弹的特性计算出弹道曲线，然后再调整瞄准镜进行射击，由于计算出弹道曲线在瞄准射击中很重要的一个数据就是瞄准镜中心线和枪管中心线的距离，或称为瞄准镜高度，由于更换上的数码瞄准镜和原来的传统瞄准镜在绝大多数情况下都是不同的，如果射手希望达到更高的精度，那就必须测量出更换上的瞄准镜高度，用新的瞄准镜高度计算出弹道曲线，才能准确射击，这又是一个繁杂的过程。同时又由于在白昼时传统的望远镜式瞄准镜在可靠性，稳定性，准确性和远距离的清晰度方面是拥有绝对优势的，这时又需要将传统的望远镜式瞄准镜换回去，瞄准镜换回去后很难不产生位移，这时又需要重新进行归零程序，频繁地更换瞄准镜又频繁地归零显然不是办法；如果不更换瞄准镜而选择在枪上再增加一个数码瞄准镜，由于枪前视方向的轮廓线面积对枪的使用方便程度起很大的作用，在瞄准镜侧面加上一个数码瞄准镜会因为大幅增加枪的前视方向的轮廓线面积会给枪的使用带来巨大不便，甚至造成磕碰损坏，在瞄准镜正前方加个数码瞄准镜又会完全挡住瞄准镜视线，归零的难度又会增加很多。由此可见，传统瞄准镜无法在低照度条件下使用，要在低照度条件下使用数码瞄准镜功能，繁杂且不方便。
 技术解决方案
为了解决上述问题，本发明提出一种能快捷方便使用的辅助光学系统，可以被快速安装在传统的望远镜式瞄准镜上，使得枪械无需更换传统瞄准镜就可以具有数码瞄准镜的特殊环境条件如低照度条件下的瞄准功能，无需实弹射击就可以快速归零，同时通过部分重叠设计大幅减少瞄准镜在枪的前视方向轮廓线上突出的面积，方便射手使用，提升使用效率。

 本发明的最佳实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
请参考图1至图5，为本发明提供的一种辅助光学系统，该系统安装于枪200上的望远镜式瞄准镜203，所述瞄准镜203包括目镜端2032、物镜端2033，以及从目镜端2032看到的第一分划线2031，所述目镜端2032安装有目镜2037，物镜端2033安装有物镜2034。本发明的瞄准镜203安装于枪200的枪体201上,同时，瞄准镜203上设置有左右调节旋钮2035，及高低调节旋钮2036。
本发明的辅助光学系统包括数码成像部10、显示部20、第一固定部30和第二固定部31，数码成像部10通过第一固定部30固定在物镜端2033并部分遮挡物镜2034，使得数码成像部10和物镜端2033在瞄准镜203的视线方向部分重叠。本发明通过部分重叠设计大幅减少数码成像部10在枪200的前视方向轮廓线上突出的面积，这样可以避免由轮廓线上突出的面积给枪的使用带来的巨大不便，并避免了容易造成的磕碰损坏。经过实验和观察，本发明实施例的瞄准镜203的物镜2034被遮挡三分之二甚至更多时，仍然可以用瞄准镜203来实现数码成像部10的校准功能，由此可见这种重叠设计减少了数码成像部10在枪的前视方向轮廓线上突出的面积是非常有效的设计点。
本发明的显示部20设置有显示屏21，显示部20通过第二固定部31固定在目镜端2032并与数码成像部10电连接，该电连接为有线或者无线连接。
本发明的数码成像部10将环境影像感光成像并转换成视频信号，并生成可移动调节且与所述第一分划线2031功能相同的第二分划线211，数码成像部10将所述第二分划线211与视频信号叠加后传输至显示部20进行显示，如图5中所示。
即生成的第二分划线211具有与第一分划线2031相同的瞄准及调节功能，射手可以直接使用显示屏21上的第二分划线211进行瞄准。
数码成像部10能在特殊环境条件如低照度条件下准确地瞄准目标，这样，本发明的辅助光学系统可直接在原有传统的望远镜式瞄准镜上获得数码瞄准镜的功能而无需更换望远镜式瞄准镜，无需实弹射击就能在有风或无风的环境里无声无息完成归零，并能够快速完成调节，能让射手使用和瞄准镜相同的弹道计算方式、使用和瞄准镜的分划线相同瞄准点瞄准射击，使用完成后可快速拆卸，且通过将数码成像部与瞄准镜的物镜部分重叠设计，大幅减少其在枪的前视方向轮廓线上突出的面积，极大地提高了方便度和使用效率。
优选地，本发明实施例中，显示部20和第二固定部31转动连接以将显示部折叠或展开。从而节省枪200的前视方向轮廓线上突出的面积。
在不使用时将显示部20折叠靠近且平行于瞄准镜203的目镜端2032，使用时打开到和目镜端2032垂直的位置。
可以理解，在实际运用中，只要方便使用瞄准镜203瞄准时看清显示部20的显示屏21，显示部20还可以使用其它方式和在其它位置固定。
可以理解，在实际运用中，本发明的数码成像部10可安装在物镜端2033的任意位置并部分遮挡所述物镜端2033的物镜2034。
优选地，本发明实施例的数码成像部10安装在物镜端2033的正上方并部分遮挡所述物镜端2033的物镜2034。设置在物镜端2033的正上方，避免了数码成像部10在枪200的左右轮廓线上突出而影响使用。
优选地，本发明实施例的第二分划线211与第一分划线2031的调节值相同。即第二分划线211与第一分划线2031的调节范围相同，每格所对应的调节值相同。
进一步地，本发明实施例的第二分划线211上的点所对应的目标距离的瞄准位置与第一分划线2031上相同的点所对应的相同目标距离的瞄准位置重合。即在第二分划线211上看到的点与第一分划线2031上相同的点所对应的相同目标距离处的瞄准位置是同一位置，两个点所对应的目标位置是重合的，这样使得射手可直接使用显示屏21上的第二分划线211对目标进行瞄准，方便射手使用。
同时，由于第一分划线2031和第二分划线211的瞄准位置重合，只要瞄准镜203完成归零或处于归零状态时，数码成像部10也就自动归零。
具体地，如图1和图2所示，本发明的第一固定部30包括第一固定环301、第二固定环302和重叠盖板303，第一固定环301安装于瞄准镜203的物镜端2033，数码成像部10安装在第二固定环302内，重叠盖板303的一面和第一固定环301的外缘部分连接且部分遮住第一固定环301的内圈，从而部分遮住瞄准镜203的物镜2034，重叠盖板303的另一面和第二固定环302相连，使得数码成像部10和瞄准镜203的物镜端2033在瞄准镜203的视线方向部分重叠。这样可以大幅减少数码成像部10在枪200的前视方向轮廓线上突出的面积，避免了使用不便及容易造成的磕碰损坏。
如图1中所示，本发明辅助光学系统的数码成像部10包括镜头11、外壳12、按键13、感光模块14、屏幕信息显示模块15和电源模块16。
感光模块14、屏幕信息显示模块15和电源模块16安装于外壳12内，镜头11安装于外壳12前端，按键13安装于外壳12上。
感光模块14包括感光芯片141，所述镜头11将环境影像成像于感光模块14的感光芯片141上，感光模块14将感光芯片141感知到的环境影像转换成视频信号并传输给屏幕信息显示模块15，如图4中的模块组成所示。
按键13用于对屏幕信息显示模块15进行设置选择以及输入数据给屏幕信息显示模块15。
屏幕信息显示模块15包括设置程序151用于设置，并根据视频信号和显示部20内显示屏21的特性，将输入的数据进行计算，生成可移动调节的第二分划线211叠加到视频信号一起传输到显示部20，如图4中的模块组成所示。
电源模块16为数码成像部10和显示部20提供电源。
显示部20通过第二固定部31固定于瞄准镜203的目镜端2032且和数码成像部10电连接，显示部20的显示屏21显示由屏幕信息显示模块15传输来的信号；按键13包括功能键131、上键132、下键133、左键134、右键135和确定键136。
屏幕信息显示模块15内置字符发生芯片，屏幕信息显示又称OSD，OSD 是 On Screen Display 的缩写，常被应用在 CRT/LCD等显示屏上，利用字符发生芯片在显示部20的显示屏21上显示需要的字符，在显示屏21的荧幕中产生一些特殊的字形或图形，让使用者得到一些讯息，多用于在视频信号上叠加摄像头位置、日期、时间等固定信息。
优选地，本发明屏幕信息显示模块15通过瞄准镜203的第一分划线2031的调节范围计算出第一分划线2031的每格调节值对应在显示屏21的像素数量，并在显示屏21上生成一个调节值和瞄准镜203的第一分划线2031相同的第二分划线211。即本发明在显示屏21上设置出一个与第一分划线2031具有相同调节值的第二分划线211，其与第一分划线2031调节范围和射角调节值相同。
优选地，本发明屏幕信息显示模块15通过瞄准镜203的物镜端2033与数码成像部10的镜头11在水平方向的中心距和垂直方向的中心距在显示屏21上确定出一个平行瞄准点，该平行瞄准点为数码成像部10的镜头11的瞄准线对应在显示部20的显示屏21上的一个像素点，且该像素点对应的数码成像部10的镜头11的瞄准线与瞄准镜203的第一分划线2031的中心点的瞄准线平行。平行瞄准点用于确定第二分划线211的中心点。显示屏21上的平行瞄准点确定后，显示屏21上的第二分划线211的位置也确定，第二分划线211的调节值及位置确定后即可用于瞄准。
优选地，本发明所述屏幕信息显示模块15根据输入目标距离，将显示屏21上的平行瞄准点分别在水平方向和垂直方向移动与该目标距离对应的补偿值而自动补偿生成第二分划线211。
由于本发明辅助光学系统的数码成像部10的镜头11与物镜端2033的物镜2034是有偏移而不是完全重合的，故需要进行补偿，而使第二分划线211与第一分划线2031的瞄准目标是重合的，而便于射手的瞄准射击。
具体地，本发明实施例的自动补偿过程包括：
所述屏幕信息显示模块15根据输入的目标距离计算出瞄准镜203的物镜端2033与数码成像部10的镜头11在水平方向的中心距和垂直方向的中心距在显示屏21上所对应像素数量的值。
将平行瞄准点分别在水平方向和垂直方向移动所述计算出来的像素数量的值到一个新的像素点的位置，并以这个新的像素点为中心在显示屏21上生成一个调节值和瞄准镜的第一分划线2031相同的第二分划线211，该第二分划线211每一点对应数码成像部10的镜头11在目标距离的瞄准位置和瞄准镜203的第一分划线2031上相同的点在相同目标距离的瞄准位置重合。
经过自动补偿后，第二分划线211每一点对应数码成像部10的镜头11在目标距离的瞄准位置和瞄准镜203的第一分划线2031上相同的点在相同目标距离的瞄准位置重合。这样使得射手可直接使用显示屏21上的第二分划线211对目标进行瞄准，而无需进行物镜端2033与数码成像部10偏移距离的转换，提高瞄准效率，方便射手使用。
本发明的辅助光学系统，由于数码成像部10的镜头11和感光芯片141的相对位置是固定的，因此生成的视频信号在显示部20的显示屏21上的位置也是固定的，显示屏21上的像素点，对应的就是数码成像部10的镜头11成像的环境的位置，也就是说显示部20的显示屏21上的每个像素点对应的是一条数码成像部10的镜头11的瞄准线，因此数码成像部10的屏幕信息显示模块15生成的显示在显示部20的显示屏21上的第二分划线211，也可以像瞄准镜203的第一分划线2031一样，具有可以用来瞄准的功能；同时，由于显示屏21上显示的第二分划线211是屏幕信息显示模块15经过计算准确显示在每个像素上的，也就等于屏幕信息显示模块15知道显示在显示屏21上的每个像素的信号的位置，或者说屏幕信息显示模块15能感知显示屏21显示叠加内容的每个点的位置；显示屏21能够指示的数码成像部10的瞄准功能的最小调节值，就是显示屏21每个点之间的距离，即显示屏21的像素。而且由于瞄准镜203和数码成像部10的相对位置时固定的，使得射手可以借助瞄准镜203的第一分划线2031的瞄准目标和调节射角的功能在显示部20的显示屏21上对数码成像部10进行校准、调节和设置。
具体的实现如下：
第一步：在一定的距离用瞄准镜203的第一分划线2031找出相距一定格数的两个点的位置，然后在显示部20的显示屏21上找出这两个点的像素位置，从而使屏幕信息显示模块15获得这两个点之间的像素数量，并将这两个点之间的像素数量除以这两点之间对应的瞄准镜203的第一分划线2031的格数，便可计算出瞄准镜203的第一分划线2031的每格的调节值对应的显示部20的显示屏21的像素数量，使得屏幕信息显示模块15在显示部20的显示屏21上生成一个调节值和瞄准镜203的第一分划线2031相同的第二分划线211。
第二步：屏幕信息显示模块15计算出在不同的目标距离时瞄准镜203的物镜端2033与数码成像部10的镜头11的在水平方向的中心距和垂直方向的中心距在显示部20的显示屏21上分别相当的像素数量，把这两个像素数量称作补偿值。
第三步：在一定的距离找出和瞄准镜203的物镜端2033与数码成像部10的镜头11的在水平方向的中心距和垂直方向的中心距都相同的两个点，用瞄准镜203的第一分划线2031上的一个点对准对应的点的同时移动显示屏21上的第二分划线211使显示屏21上的第二分划线211和瞄准镜203的第一分划线2031相同的点对准在显示屏21上看到的对应的另一个点，从而使屏幕信息显示模块15确定出显示屏21上的第二分划线211的中心点的像素点位置即像素点P，这个即像素点P对应的数码成像部10的镜头11的瞄准线和瞄准镜203的第一分划线2031的中心点的瞄准线是平行的，因而被称作平行瞄准点，从而使屏幕信息显示模块15在显示部20的显示屏21上以平行瞄准点为中心生成一个调节值和瞄准镜203的第一分划线2031相同的第二分划线211，且生成的第二分划线211每一点在相同距离上对准的位置和瞄准镜203的第一分划线2031相同的点对准的位置的水平方向的距离和垂直方向的距离和瞄准镜203的物镜端2033与数码成像部10的镜头11的在水平方向的中心距和垂直方向的中心距都相同。
只要输入目标距离，屏幕信息显示模块15将显示部20的显示屏21上的平行瞄准点分别在水平方向和垂直方向移动相应的目标距离的补偿值到一个新的像素点的位置，这个新的像素点对应的数码成像部10的镜头11在目标距离的瞄准位置和瞄准镜203的第一分划线2031的中心点在相同目标距离的瞄准位置是重合的，屏幕信息显示模块15在显示部20的显示屏21上以这个新像素点为中心生成一个调节值和瞄准镜203的第一分划线2031相同的第二分划线211，且生成的第二分划线211每一点对应的数码成像部10的镜头11在目标距离的瞄准位置和瞄准镜203的第一分划线2031上相同的点在相同目标距离的瞄准位置是重合的，即生成一个和瞄准镜203的第一分划线2031在相同目标距离的瞄准位置相同的第二分划线211，使得射手可以像使用瞄准镜203的第一分划线2031一样使用屏幕信息显示模块15生成并显示在显示部20的显示屏21上的第二分划线211对目标进行弹道计算，然后进行瞄准射击；由于瞄准镜203已经归零，那么在目标距离时的瞄准位置和瞄准镜203的第一分划线2031的瞄准位置相同的第二分划线211的数码成像部10自然就已经等于归零了。
为了实现以上功能，本发明的辅助光学系统需要进行如图6所示的设置，包括：设置分划线、设置补偿值、设置平行瞄准点。
本发明的辅助光学系统在安装之前，先将瞄准镜203的第一分划线2031中心点对准一定距离外的一个点A，如图8中所示，然后标记出此时第一分划线2031最底下的刻度点对准相同距离的位置B；再将瞄准镜203的第一分划线2031中心点对准一定距离外的一个点E（未示出），然后标记出此时第一分划线2031最左边的刻度的点对准相同距离的的位置F(未示出)。本发明的辅助光学系统在枪200上安装好后，先需要通过屏幕信息显示模块15的设置程序151依照设置步骤进行设置，如图7所示，首先要量出瞄准镜203的物镜端2033和数码成像部10的镜头11的在水平方向的中心距X和垂直方向的中心距Y，并以瞄准镜视线方向的数码成像部10的镜头11的中心点C为坐标原点，坐标原点上垂直坐标轴的上方为正下方为负，水平坐标轴右边为正左边为负，瞄准镜203的物镜端2033中心点S所在的坐标的位置的水平坐标值为x，垂直坐标值为y，且|x|=X，|y|=Y；请参考图10，然后在一定的距离外且瞄准镜203和数码成像部10都能清晰看到的地方找出两个点S1、C1，以C1点为坐标原点，S1点的水平坐标值为x，垂直坐标值为y，然后长按模式键131，在显示部20的显示屏21上看到设置菜单。
设置菜单包括：1.设置分划线、2.设置补偿值、3.设置平行瞄准点、4. 重新设置平行瞄准点、5.退出设置。
设置步骤一，按上键132或下键133选择后按确定键136进入菜单“1.设置分划线”选项，这时显示部20的显示屏21显示“设置纵向分划线，请输入纵向分划线格数【】”， 按上键132、下键133、左键134、右键135在括号里输入瞄准镜203的第一分划线2031从中心点到最底下的刻度的格数Uv，通常都是10格，然后按确定键进入下一步，这时在显示部20的显示屏21上看到两个十字线，接着按上键132、下键133、左键134、右键135将在显示部20的显示屏21上看到的其中一个可移动的十字线的中心点移动到显示屏21上看到的A点的位置，这时这个十字线中心点对应的位置是显示屏上一个像素点Va，按确定键136然后将在显示部20的显示屏21上看到的另一个可移动的十字线的中心点移动到显示屏21上看到的B点的位置，这时这个十字线中心点对应的位置是显示屏上一个像素点Vb，按确定键136完成这一步设置，完成这一步设置时屏幕信息显示模块15获得了显示屏21上的一个像素点Va和像素点Vb之间的像素点数量Pv，这个像素点数量Pv指示的是数码成像部10的感光芯片141透过镜头11的瞄准线在A点和B点之间的角度值，和瞄准镜203的第一分划线2031在中心点和最底下的刻度中心点指示的瞄准镜203的瞄准线在A点和B点之间的角度值即调节值是一样的，把这个像素点数量Pv除以上一步输入的瞄准镜203的第一分划线2031从中心点到最底下的刻度的格数Uv，就可以计算出第一分划线2031垂直方向每格调节值对应的显示部20的显示屏21的像素点数量Vp，这时屏幕信息显示模块15就可以在显示部20的显示屏21上以屏幕中心的一个像素点Cc为中心在垂直方向每Vp点一个格生成一条垂直方向的分划线，而且它的每一格和瞄准镜203的第一分划线2031在垂直方向的每一格指示的角度值是一样的。然后进入下一步设置，这时屏幕显示“设置横向分划线，请输入横向分划线格数【】”，按上键132、下键133、左键134、右键135在括号里输入瞄准镜203的第一分划线2031从中心点到最左边的刻度的格数Uh，通常都是10格，然后按确定键136进入下一步，这时在显示部20的显示屏21上看到两个十字线，将在显示部20的显示屏21上看到的其中一个可移动的十字线的中心点移动到显示屏21上看到的E点的位置，这时这个十字线中心点对应的位置是显示屏上一个像素点He，按确定键136，然后将在显示部20的显示屏21上看到的另一个可移动的十字线的中心点移动到显示屏21上看到的F点的位置，这时这个十字线中心点对应的位置是显示屏上一个像素点Hf，按确定键136完成并返回设置菜单，完成这一步设置时屏幕信息显示模块15获得了显示屏21上的一个像素点He和像素点Hf之间的像素点数量Ph，这个像素点数量Ph指示的是数码成像部10的感光芯片141透过镜头11的瞄准线在E点和F点之间的角度值，和瞄准镜203的第一分划线2031在中心点和最左边的刻度的中心点指示的瞄准镜203的瞄准线在E点和F点之间的角度值即调节值是一样的，把这个像素点数量Ph除以上一步输入的瞄准镜203的第一分划线2031从中心点到最左边的刻度的格数Uh，就可以计算出第一分划线2031水平方向每格调节值对应的显示部20的显示屏21的像素点数量Hp，这时屏幕信息显示模块15就可以在显示部20的显示屏21上以屏幕中心的一个像素点Cc为中心在水平方向每Hp点一个格生成一条水平方向的分划线，且它的每一格的调节值和瞄准镜203的第一分划线2031在水平方向的每一格的调节值是一样的。将横向和纵向分开计算是因为显示部20的显示屏21的像素点横向和纵向的距离不一定是相同的。完成菜单“1.设置分划线”后屏幕信息显示模块15以屏幕中心的一个像素点Cc为中心生成了一个枪200的射角调节值和瞄准镜203的第一分划线2031相同的第二分划线211。
设置步骤二，选择进入菜单“2.设置补偿值”选项，这时显示部20的显示屏21显示“请输入水平坐标值【】”， 按上键132、下键133、左键134、右键135在括号里输入以瞄准镜203视线方向的数码成像部10的镜头11的中心点C为坐标原点，瞄准镜203的物镜端2033中心点S所在的坐标的位置的水平坐标值x， 然后按确定键136进入下一步，这时显示部20的显示屏21显示“请输入垂直坐标值【】”，在括号里输入以瞄准镜203视线方向的数码成像部10的镜头11的中心点C为坐标原点，瞄准镜203的物镜端2033中心点S所在的坐标的位置的垂直坐标值y，按确定键136完成并返回设置菜单，完成这一步设置时屏幕信息显示模块15获得了坐标值x和坐标值y，只要知道目标的距离t，就可以计算出在距离为t时数码成像部10的感光芯片141透过镜头11在相距x的两点之间的瞄准线的角度值ax，请参考图9，也就是显示部20的显示屏21的水平方向的像素数量值Px。
计算过程是这样的，假设瞄准镜203的第一分划线2031一格的值为1分角（或1MOA），1MOA是1度的1/60，即以t为半径的圆周长2πt被分成21600份，每一份的长度对应的是瞄准镜203的第一分划线2031一格的值2πt/21600，由于圆弧半径很大，圆弧长度很小，两点间的直线距离和弧线距离之间的差别可以忽略不计，因此距离为t时数码成像部10的感光芯片141透过镜头11在相距x的两点之间的瞄准线的角度值就是ax=x/(2πt/21600)=x*21600/2πt，也就是显示部20的显示屏21的水平方向的像素数量值Px=Hp*x*21600/2πt，也同样可以计算出在距离为t时数码成像部10的感光芯片141透过镜头11在相距y的两点之间的瞄准线的角度值，也就是显示部20的显示屏21的垂直方向的像素数量值Py=Vp*y*21600/2πt，由于Hp、x、Vp、y的值前面屏幕信息显示模块15都已获得，只要知道目标的距离t，屏幕信息显示模块15就可以计算出Px和Py值，Px和Py值称作补偿值。
设置步骤三，选择进入菜单 “3.设置平行瞄准点”选项，这时在显示部20的显示屏21上出现一个经过上述设置步骤一完成后的第二分划线211， 这时将瞄准镜203的第一分划线2031上的一个点对准点S1，然后按上键132、下键133、左键134、右键135将在显示部20的显示屏21上看到的第二分划线211的相同位置的点移动到显示屏21上看到的C1点的位置，确定了第二分划线211上一个点的位置，自然也就确定了第二分划线211中心点的位置，它对应是显示屏21上一个像素点P的位置，请参考图10，本图列举了瞄准镜203的物镜端2033的中心点和数码成像部10的镜头11的中心点在垂直方向同在一条直线的情形，即水平方向的中心距x=0，在实际使用中，为了便于使用或安装其它设备，瞄准镜203的物镜端2033的中心点和数码成像部10的镜头11的中心点在水平方向和垂直方向是可以不在一条直线上的。
移动完成后按确定键136完成设置返回设置菜单，这时屏幕信息显示模块15获得了显示屏21上的一个像素点P的位置，这个像素点P对应的是数码成像部10的感光模块14的感光芯片141上的一个点，它通过数码成像部10的镜头11后形成的瞄准线和瞄准镜203的第一分划线2031的中心点的瞄准线平行的，因此在相同距离时像素点P上看到的目标的位置和瞄准镜203的第一分划线2031的中心点看到目标的位置在水平方向的距离是X且在垂直方向的的距离是Y，因此像素点P称作平行瞄准点。
完成以上三个步骤的设置，设置就完成了，对于已经完成设置的辅助光学系统在从枪200上使用后拆卸下来，重新装上使用时，除了它的平行瞄准点P可能发生位移外，其它的数据都是一样的，因此只要选择进入菜单“4. 重新设置平行瞄准点”选项，重新进行上面的设置步骤三的过程，按确定键136完成设置返回设置菜单，这时屏幕信息显示模块15获得了显示屏21上的一个新的像素点P的位置，即设置了平行瞄准点就完成了设置过程，这样经过重新设置的辅助光学系统就可以快速投入使用，非常方便。
完成设置后，屏幕信息显示模块15在显示部20的显示屏21上以平行瞄准点为中心生成一个调节值和瞄准镜203的第一分划线2031相同的第二分划线211，且生成的第二分划线211每一点在相同距离上对准的位置和瞄准镜203的分划线2031相同的点对准的位置的水平方向的距离和垂直方向的距离和瞄准镜203的物镜端2033与数码成像部10的镜头11的在水平方向的中心距和垂直方向的中心距都相同，这时的第二分划线211实际上已经可以用来瞄准了，但是计算稍有不便。
如果要得到更好用的第二分划线211，短按功能键131进入工作状态，按上键132、下键133、左键134、右键135输入目标的距离t的值按确定键136，屏幕信息显示模块15就可以根据公式Px=Hp*x*21600/2πt和Py=Vp*y*21600/2πt计算出补偿值Px和Py，在显示部20的显示屏21上以像素点P为坐标原点横向移动Px，纵向移动Py至Pt点，这个Pt点对应的数码成像部10的镜头11在目标距离的瞄准位置和瞄准镜203的第一分划线2031的中心点在相同目标距离的瞄准位置是重合的，屏幕信息显示模块15在显示部20的显示屏21上以这个新像素点Pt为中心生成一个调节值和瞄准镜203的第一分划线2031相同的第二分划线211，且生成的第二分划线211每一点对应的数码成像部10的镜头11在目标距离的瞄准位置和瞄准镜203的第一分划线2031上相同的点在相同目标距离的瞄准位置是重合的，即生成一个和瞄准镜203的第一分划线2031在目标距离的瞄准位置相同的第二分划线211，使得射手可以像使用瞄准镜203的第一分划线2031一样使用数码成像部10的屏幕信息显示模块15生成的显示在显示部20的显示屏21上的第二分划线211对目标进行弹道计算，然后进行瞄准射击。射手无需更换瞄准镜203就能通过用本发明的辅助光学系统实现特殊环境条件如低照度条件下的数码瞄准镜的功能，无需实弹射击就能在有风或无风的环境里无声无息完成归零，并能够快速完成调节，能让射手使用和瞄准镜203相同的弹道计算方式、使用和瞄准镜203的第一分划线2031相同瞄准点瞄准射击。
本发明的辅助光学系统，通过将数码成像部10与瞄准镜203的物镜2034部分重叠设计,大幅减少其在枪200的前视方向轮廓线上突出的面积，同时使得射手能利用原有传统瞄准镜的功能对数码成像部10进行校准，无需更换瞄准镜就能通过用本发明的辅助光学系统实现特殊环境条件如低照度条件下的数码瞄准镜的功能，无需实弹射击就能在有风或无风的环境里无声无息完成归零，并能够快速完成调节，能让射手使用和瞄准镜相同的弹道计算方式、使用和瞄准镜的分划线相同瞄准点瞄准射击，极大地提高了方便度和使用效率。
尽管上面已经示出和描述了本发明的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本发明的限制，本领域的普通技术人员在不脱离本发明的原理和宗旨的情况下在本发明的范围内可以对上述实施例进行变化、修改、替换和变型。
