Description

无光程差分光装置
技术领域
本发明涉及望远镜、 观靶镜、 瞄准镜等光学成像系统会聚光路中的分光装 置， 具体涉及一种无光程差分光装置。 该装置以无光程差分光为特征， 在移 出、 移入光路时， 无光程差， 不需重新调焦， 从而使目视观察和数码照相切 换更加方便。
背景技术
在普通光学瞄准的望远镜中， 人们直接从目镜中观察和捕捉目标。 这种望 远镜只能用于观察， 不能照相， 其光路原理见图 1所示， 平行光经物镜 1成 像在位于焦点 F 的焦平面上， 人眼 3在目镜 2中进行瞄准和观察。
为了用望远镜实现既能瞄准观察， 又能照相的功能， 需要在图 1的焦点 F， 前插入一分光镜， 使光线在分光面上分成二路， 其中， 一路透射到目镜 2, 用于人眼瞄准观察， 而另一路反射至影傳 _传感器 7 (见图 3 ), 用于照相。 图 2(a)为没有插入分光镜时的光路原理图， 入射平行光线通过物镜 1后， 会聚 成像在通过焦点 F 的焦平面上。 图 2(b)为插入分光镜时的光路原理图， 图 示在物镜 1和焦点 F 间插入一传统的立方棱镜分光镜， 该分光镜由二块直 角棱镜 6胶合而成， 在中间胶^ !·面上镀有分光膜 5， 使光线在分光面上分 成二路， 一路透射， 另一路反射。 而加入立方棱镜分光镜后， 由于分光棱镜 的折射率 n玻与空气的折射率 n不同 (一般情况下， 空气的折射率 n近似 1, 而玻璃的折射率 n玻约为 1.5左右）， 因此在光路中， 若分光镜的厚度为 L, 通过厚度为 L玻璃的光程为 L/ n 玻=1 1.5=0.671^, 与不加入分光镜时的光程 差 A=L— L/ n玻 =0.33L, 即像面需往后移 0.33L。 分光棱镜的厚度越大， 光程 差也越大， 像面需移动的距离也越大。
数码望远镜可以利用以上分光原理来实现， 即在物镜与焦点 F， 间插入一 立方棱鏡分光镜， 使透过物镜的光线在分光镜分光面上分成二路， 一路透射 到达目镜， 由人眼瞄准观察， 另一路反射到光学影像传感器， 用于照相， 见 图 3所示。 在立方棱镜分光镜的设置上， 有两种方式， 第一种是将分光镜固 定在会聚光路中； 第二种是采用一个移动或转动机构将分光镜安置在望远镜 中， 通过移入、 移出光路来实现单纯观察与瞄准照相之间的功能切换。
针对现有技术， 从分光镜本身来看， 采用立方棱镜有以下三点不足： 1、 所需尺寸大， 分光面要镀分光膜， 不易制作， 再加精密的棱镜材料， 成本高；
2、 镀分光膜易产生颜色失真及光线的损耗；
3、 因尺寸大， 移入、 移出光路时， 会产生较大的光程差。
从立方棱镜分光镜的两种设置方式来看， 第一种方式不论瞄准观察或照相 分光镜均固定在光路中， 这样透过物镜的光线就要分为二部份， 分别用于瞄 准观察和照相， 使光能损失较大， 将会影响观察和照相的效果。 第二种方式 在使用瞄准照相功能时需将分光镜移入光路， 而在使用单纯观察功能时可将 分光镜移出光路。 这样虽能减少光能损失， 使单纯观察变得更加清楚， 但由 于分光镜的移入， 移出， 在目视观察光路中产生的光程差， 又使目镜需要重 新调焦。 显然两种方式均存在明显缺陷。
发明内容
本发明提出了一种光学成像系统会聚光路中的无光程差分光装置， 其目的 是使分光镜在会聚光路中移入、 移出切换时无光程差， 从而避免目镜重新调 焦。
为达到上述目的， 本发明采用的技术方案是： 一种光学成像系统会聚光路 中的无光程差分光装置， 由一插入会聚光路物镜与焦点 F， 之间的分光镜构 成， 所述分光镜为一反射镜， 反射镜的反射面与光轴成角度， 该反射镜上有 一通孔， 经过物镜的光线一部分穿过通孔聚焦成像， 另一部分经过反射面反 射后聚焦成像。
上述技术方案中的有关内容解释如下：
1、 上述方案中， 所述反射镜上的通孔设在反射镜中心位置较好， 此时通 孔的轴线与光轴重合。
2、 上述方案中， 为了筒化结构， 所述反射镜通孔的轴线与反射面成 45° 角。
3、 上述方案中， 所述反射镜可以由平板镜片构成， 其反射面镀有全反射 膜。 平板镜片可以由玻璃或其它材料构成。
4、 上述方案中， 所述反射镜由一移动或转动机构支撑， 并在移入和移出 光路两种工作状态之间进行切换， 以此实现单纯观察和瞄准照相两种功能。 也可以将反射镜固定设置在光路中。
5、 关于反射镜中心通孔的孔径 d尺寸， 应根据目视和照相对亮度的不同 要求， 按照孔的面积和物镜成像光束在反射镜上所截光斑面积之比确定， 选 择合适比例， 一般在 5%〜30%范围内， 较好的可取 10%左右。 本发明工作原理是： 将中心有孔反射镜移入光路， 见图 6 ( a )所示， 光 路中心部分的光线通过中心孔， 到达焦面， 见图中的阴影部分。 其余大部分 光线， 由反射镜中心孔外的光斑反射面反射， 构成另一路光线， 见图 6 ( b ) 所示阴影部分。 从图 6 ( a )与图 6 ( b )的比较可以看出， 两路光线从分光面 到达像面的距离相等， 即 L1 = L2。 当单独用于目视瞄准观察时， 将反射镜 移出光路， 此时通过物镜的光线不受反射镜中心孔限制， 全部成像在目镜视 场内， 能够获得足够的亮度。 当用于照相时， 将中心有孔的反射镜移入光路， 此时， 光线分成两部分， 通过中心孔部分的光线成像在目镜视场， 用于目视 观察， 其余部分光线经反射面反射， 有 90%左右的光能射到影像传感器， 有 足够的光能用于照相。 在中心有孔反射镜移入和移出光路的整个过程中， 目 视光路中的光程都一样， 没有变化， 不产生光程差， 因而是一个无光程差的 分光系统。
由于上述技术方案运用， 本发明与现有技术相比具有下列优点和效果：
1、 本发明分光镜易生产、 只要一块中间有孔的平板玻璃， 一面镀全反射 膜即可进行光路分光；
2、 本发明分光镜只镀全反射膜， 不产生分光颜色失真；
3、 本发明分光镜移入、 移出光路时， 不产生光程差， 目视观察时不需要 重新调焦。

实施例： 参见图 7所示， 一种用于数码望远镜的无光程差分光装置， 由一 插入会聚光路物镜 1 与焦点 F 之间的分光镜构成， 所述分光镜为一反射镜 8, 见图 4和图 5所示， 该反射镜 8中心有一通孔 9, 通孔 9的轴线与光轴 12 重合， 并与反射镜 8的反射面成 45° 角。 反射镜 8由平板玻璃构成， 其反射 面镀有全反射膜 10 (见图 4 )。 反射镜中心通孔 9的孔径 d尺寸， 按照孔的面 积和物镜成像光束在分光镜上所截光斑面积之比确定， 选择合适比例， 一般 可取 10%左右。 为了使数码望远镜同时具有单独观察和瞄准照相两种功能， 反射镜 8 由一移动或转动机构支撑， 并在移入和移出光路两种工作状态之间 进行切换。 当单独用于目视瞄准观察时， 通过移动或转动机构将反射镜 8移 出光路， 此时通过物镜 1的光线不受反射镜 8中心通孔 9的限制， 全部成像 在目镜 2视场内， 能够获得足够的亮度， 见图 1所示。 当用于照相时， 将中 心有通孔 9的反射镜 8移入光路， 此时， 光线分成两部分， 通过中心通孔 9 部分的光线成像在目镜 2视场， 用于目视观察， 见图 6 ( a ) 中的阴影部分； 其余部分光线经反射面反射， 有 90%左右的光能射到影像传感器 7， 有足够 的光能用于照相， 见图 6 ( b ) 中的阴影部分。 在中心有通孔 9的反射镜 8移 入和移出光路的整个过程中， 目视观察光路的光程不发生变化。
图 8为图 7中的 A向分光光束分布图，图中阴影部分表示反射光束截面 11。 本发明除了用于数码望远镜外， 也能用于其它类似的会聚光路中， 达到分 光切换时无光程差的目的。
