实施例二
下面对本申请实施例提供的光学成像系统的光路规划进行详细说明。
在本申请实施例中，可以在光学成像系统中采用具有透射、折射、反射等光学特性的光学元件来规划第一入射光对应的第一光路和第二入射光对应的第二光路。
举例来说，在光学成像系统中，感光元件可位于所述第一入射光的透射光路之外的区 域。其中，所述第一入射光的透射光路为所述第一入射光未被反射时能够到达的空间。
示例性地，感光元件可位于第二入射光的透射光路上，或者，感光元件可位于第二入射光的透射光路之外的区域。
需要说明的是，在本申请实施例中，入射光从入光口入射系统时，入射光与垂直于入光口所在平面的直线之间的夹角可以属于预设的倾斜角范围。基于入射光的倾斜角范围，各个入射光对应的透射光路的含义可以为满足倾斜角范围的入射光沿入射方向穿过对应的入光区之后，在未被反射时所能够到达的空间。举例来说，透射光路可以包括入射光经过具有光焦度的透光元件、不具有光焦度的透光元件时所能够到达的空间。在一示例中，当入射光的传播光路上未设置有透光元件和反光元件时，任一入射光的透射光路可以包括：满足倾斜角范围的所有入射光穿过对应的入光口后，在不改变传播方向传播时所能够到达的空间。在又一示例中，当入射光的传播光路上设置有具有光焦度的透光元件时，任一入射光的透射光路可以包括：满足倾斜角范围的所有入射光穿过对应的入光区后，沿入射方向传播至到达具有光焦度的透光元件所能够到达的空间以及经过具有光焦度的透光元件折射后的入射光所能够到达的空间。
可参看图3A所示，作为一种示例，第一入射光的透射光路可以包括第一入射光在穿过第一入光区之后且在未经过其他具有改变光的传播方向的光学器件时所能够到达的空间区域。作为一种示例，当感光元件位于第一入射光在不改变传播方向传播时能够到达的空间之外时，第一入光区在感光元件所在平面的投影可以位于所述感光元件之外的区域。当感光元件位于第二入射光在不改变传播方向传播时能够到达的空间时，第二入光区在感光元件所在平面的投影可以位于所述感光元件中。

作为一种示例，可参看图2A所示，第一透镜组件可以包括环形镜片511、环形镜片512，第二透镜组件可以包括圆形的中间镜片521、中间镜片522、中间镜片523、中间镜片524，第三透镜组件可以包括圆形的底部镜片531、底部镜片532。作为一种示例，第一透镜组件、第二透镜组件、第三透镜组件与第一入光区可以共轴心设置。需要说明的是，上述第一透镜组件、第二透镜组件、第三透镜组件不是光学成像系统必须同时具备的部件，在本申请其他实施例中将对各个透镜组件的的组合方式进行说明，此处暂不赘述。
可参看图3B，第一入射光的透射光路可以包括第一入射光沿入射方向从第一入光区传播至第一透镜组件所能够到达的空间，以及经第一透镜组件后汇聚或者发散后的第一入射光所能够到达的空间。作为一种示例，可参看图3C，第二入射光的透射光路可以包括：第二入射光沿入射方向从第二入光区传播至第二透镜组件所能够到达的空间，以及，经第二透镜组件后汇聚或者发散后的第二入射光所能够到达的空间，以及，经过第三透镜组件汇聚或者发散后的第二入射光所能够到达的空间。需要说明的是，图3C中左侧图为第二入射光与入光口所在平面的正方向之间的夹角为90度-最大倾斜角时第二入射光的透射光路的一种示意，图3C中右侧图为第二入射光与入光口所在平面的负方向之间的夹角为90度减去最大倾斜角时的第二入射光的透射光路的一种示意。在实际应用中，第二入射光的透射光路可以包括满足倾斜角范围的所有第二入射光的透射光路占用的空间的集合。
图4为本申请实施例提供的光学成像系统中第一光路为折反式光路的结构示意图一；图5A为本申请实施例提供的光学成像系统中第二光路为透射式光路的结构示意图一；图5B为本申请实施例提供的光学成像系统中第二光路为折反式光路的结构示意图。
需要说明的是，将感光元件所在平面作为三维坐标系中的X轴和Y轴所确定的平面，垂直于感光元件所在平面的方向为三维坐标系的Z轴方向，图4、图5A和图5B为与Z轴平行的剖面结构的一组示意图。
在一种可选的实施方式中，在感光元件位于第二入射光的透射光路上时，第一入射光到达感光元件时所经过的第一光路可以为图4所示的折反式光路，第二入射光到达感光元件时所经过的第二光路可以为图5A所示的透射式光路。
在本申请实施例中，如图4和图5A所示，作为一种示例，光学成像系统可以包括：位于第一入射光的透射光路上的反射镜；该反射镜可称为主反射镜，该主反射镜可用于将第一入射光反射至第一区域。在本申请其他实施例中，该主反射镜可以为反光元件，例如，凹面镜。
在本申请实施例中，如图4和图5A所示，光学成像系统可包括：反射元件，反射元件可以用于实现前述实施例所述的光路选择组件。该反射元件也可称为次反射镜。其中，在第一状态，反射元件可位于第一区域，所述反射元件可用于将到达所述第一区域的第一入射光反射至所述感光元件，在第二状态，反射元件可位于所述第一区域之外或者反射元件可以被设置为处于透光状态。需要说明的是，当反射元件位于第一区域之外或者被设置为处于透光状态时，到达第一区域的第一入射光可沿到达第一区域时的传播方向传播至感光元件之外的区域。
也就是说，在第一光路为折反式光路且第二光路为透射式光路时，第二入射光在未被反射时可以从第二入光区传播至感光元件，第一入射光可经过主反射镜反射至第一区域，再由反射元件反射至感光元件。其中，第一入射光从第一区域传播至感光元件之间的传播光路与第二入射光的透射光路可以相互不重叠。
在本申请实施例中，第一区域可以位于第二入射光的透射光路上，也可以位于第二入射光的透射光路之外的区域。在一示例中，当第一区域位于第二入射光的透射光路上时，经过第一区域反射的第一入射光的传播光路与第二入射光的传播光路可以重合。在另一示例中，当第一区域位于第二入射光的透射光路之外的区域时，第一入射光从第一区域传播至感光元件之间的传播光路与第二入射光的传播光路可以相互不重叠。
采用这种第一光路和第二光路的组合方式，可以使得两路入射光共用传播光路和感光元件，从而能够实现体积更小的光学成像系统，进一步地，当第一区域位于第一入射光的透射光路上时，光学成像系统可以采用更小尺寸的感光元件。
本申请实施例还提供一种光学成像系统的可选的实施方式，其中，感光元件可位于第二入射光的透射光路之外的区域，第一入射光到达感光元件时所经过的第一光路可以为图4所示的折反式光路，第二入射光到达感光元件时所经过的第二光路可以为图5B所示的折反式光路。
在本申请实施例中，作为一种示例，光学变焦系统可以包括多个主反射镜，如图5B 中的第一主反射镜和第二主反射镜，以下分别简称为主反1和主反2，其中，主反1可位于第一入射光的透射光路上，主反1可用于将第一入射光反射至第一区域；主反2可位于第二入射光的透射光路上，主反2可用于将第二入射光反射至第四区域。
在本申请实施例中，如图4和图5B所示，在光学成像系统中，在第一状态，反射元件可位于第一区域，所述反射元件可用于将到达所述第一区域的第一入射光出射至所述感光元件；在第二状态，反射元件可用于将到达第四区域的所述第二入射光出射至所述感光元件。
也就是说，在第一光路和第二光路均为折反式光路时，第一入射光可经过主反1反射至第一区域，再由反射元件反射至感光元件，第二入射光可经过主反2反射至第四区域，再由反射元件反射至感光元件。其中，经过第一区域反射的第一入射光的传播光路与经过第四区域反射的第二入射光的传播光路可以相互不重叠。在一示例中，经过第一区域反射的第一入射光的传播光路与经过第四区域反射的第二入射光的传播光路可以重合。
需要说明的是，上述用于将入射光反射至第一区域和第四区域的各个主反射镜不是本申请实施例提供的光学成像系统中必须存在的部件，作为一种示例，可以采用具有折射或者偏光能力的光学元件替代反射元件，并将替代元件设置于第一入射光的透射光路或者第二入射光的透射光路上，然后，通过折射或者偏光的方式将到达替代元件的一路入射光折射至感光元件。
本申请实施例还提供一种光学成像系统的可选的实施方式，在支持图4所示的第一光路和图5A所示的第二光路的基础上，光学成像系统还可以支持第三光线路径，以下简称为第三光路。其中，第三光路可以为与图5B中的第二光路类似的折反式光路。采用这种方式，光学成像系统可以支持更多种倍率的焦距。在本申请其他实施例中将进行详细说明，此处暂不赘述。
实施例三
基于前述实施例中的光路规划，在本申请实施例中，为了使得第一光路对应的光焦度与第二光路对应的光焦度不同，第一光路和第二光路上具有光焦度的对焦件有多种设置方式。
在本申请实施例中，系统中的以下部件可具有光焦度：第一透镜组件、第二透镜组件、第三透镜组件、反射镜、反射元件。
作为一种示例，可参看图2B所示，第一透镜组件，可位于第一光路上，例如，可位于第一入光区靠近感光元件的一侧；第二透镜组件，可位于第二光路上，例如，可位于第二入光区靠近感光元件的一侧；第三透镜组件，可位于第二光路，或者，可位于第二光路和第一光路上，例如，可位于感光元件靠近入光口的一侧；反射镜和反射元件可位于第一光路上。
在实际应用中，第一光路经过至少一个具有光焦度的对焦件，第二光路经过至少一个具有光焦度的对焦件。
需要说明的是，当系统中包含第一透镜组件时，反射镜和反射元件可以不是具有光焦度的器件。当反射镜或者反射元件具有光焦度时，第一透镜组件不是必须存在的部件。当系统中包含第二透镜组件时，第三透镜组件不是必须存在的部件，当系统中包含第三透镜 组件时，第二透镜组件不是必须存在的部件。
还需要说明的是，第一光路与第二光路之间可以存在重合光路，也可以不存在重合光路，其中，第一光路和第二光路中相互重叠的空间区域可以称为重合光路。当第一光路与第二光路之间存在重合光路时，光学成像系统中的对焦件可包括：位于第一光路上的对焦件、位于第二光路上的对焦件和位于重合光路上的对焦件中至少两种。当第一光路与第二光路之间不存在重合光路时，光学系统中的对焦件可包括：位于第一光路上的对焦件、位于第二光路上的对焦件，其中，位于第一光路上的对焦件的光焦度的累积值与位于第二光路上的对焦件的光焦度的累计值不同。需要说明的是，当感光元件位于第一光路与第二光路之间的重合光路上时，光学成像系统中可以设置较小的感光元件。
可参看图4、图5A和图5B所示，在本申请实施例中，作为一种示例，第一对焦件可以为位于第一光路上的任一透光元件，第二对焦件可以为位于第二光路上的任一透光元件。作为一种示例，第一光路上的所有透光元件对应的光焦度与第二光路上的所有透光元件对光焦度不同。
基于此，在第一光路对应的光焦度与第二光路对应的光焦度不同时，通过在第一光路和第二光路中切换到达感光元件的入射光所经过的光路，可以实现变焦功能。在本申请其他实施例中，在第一光路与第二光路的光程的光程的长度不同时，通过切换光路，还能够实现采用不同的调节精度进行对焦作业。此时，第一光路对应的光焦度与第二光路对应的光焦度也可以相同。
在本申请实施例中，作为一种示例，位于第一入光区的透光元件的焦距可以大于位于第二入光区附近的透光元件的焦距。焦距越大时，对入射光的传播光路的长度需求越大。因此，当光学成像系统支持的光路越大时，可以选择对应的焦距更大的对焦件。当对焦件的焦距越大时，入射光的倾斜角越小，能够使得光学成像系统的角分辨率更高，也即，单位倾斜角采集的图像的清晰度更高，在拍摄远距离物体时，能够达到更好的成像效果，例如，在用户通过缩小视场放大图像时，放大后的图像仍然具有较高的清晰度。
基于上述的光路规划，在本申请实施例中，作为一种示例，可以设置感光元件所在的平面与各入光口所在的平面之间的距离可调节。
举例来说，在实际应用中，入光口附近设置的各个透光元件可以称为前置镜组，感光元件附近设置的透光元件和主反射镜可以称为后置镜组，前置镜组可设置于前置镜筒的第一容纳腔内，后置镜组可设置于后置镜筒的第二容纳腔内，前置镜筒可沿中心线移动靠近或者远离后置镜组，以调节前置镜组与后置镜组之间的距离，通过调节前置镜组与后置镜组之间的距离可以进行更加灵活的对焦和变焦控制，进而实现图像传感器成像达到清晰度需求的目的。
需要说明的是，当第一光路上的各个对焦件之间的距离发生变化时，第一光路对应的光焦度可以变化，在一示例中，透光元件和主反射镜之间的距离可以增大或减小，主反射镜到反射元件之间的距离可以增大或减小。采用这种对焦件之间的距离可连续调节的设置方式，光学成像系统实际上实现了在一个变焦区段上的连续变焦。在实际应用中，光学成像系统可以与设置有图像处理算法的处理器相配合，实现连续变焦。
还需要说明的是，在光学成像系统中的第一光路为折反式光路时，由于光路的光程更长，因此，在调节感光元件与入光口之间的距离进行对焦时，光学成像系统支持的最大焦 距更大，因此，光学成像系统支持的对焦范围更大。

需要说明的是，感光元件可以与后置镜筒固定连接，入光口为保护玻璃。前置镜筒沿垂直于感光元件所在平面的方向移动时可以带动入光口相对于感光元件移动。当入光口与感光元件之间的距离增大(或减小)时，第一入射光对应的第一光路和第二入射光对应的第二光路的光程增大(或者减小)。作为一种示例，通过调节前置镜筒与后置镜筒之间的间距，可实现12X光学系统与5X光学系统的对焦。
在本申请实施例中，作为一种示例，对于透射光路和折反式光路来说，均可以通过调节前置镜组来实现对焦。
本申请实施例提供的光学成像系统在与图像传感器配合执行对焦成像作业时，在第一状态，反射元件设置在位于第二入射光的透射光路上的第一区域时，第一入射光经过沿第一光路传播，经过位于第一光路上且具有光焦度的器件汇聚或者发散后到达感光元件，同时将第二入射光反射至感光元件之外的区域，例如从第二入光区反射至系统外，在基于切换光路实现变焦功能的基础上，能够减少到达感光元件的噪声光对基于第一入射光进行对焦成像时的影响。
在实际应用中，举例来说，本申请实施例提供的复合式光学变焦摄像系统架构，可以为一个支持5X和12X的长焦变焦光学系统，其中，第一光路上的各个器件组成折反式光学系统，第二光路上的各个器件组成透射式光学系统，这两个系统可以分别为支持12x的光学系统和支持5x的光学系统。
此外，本申请实施例提供的光学成像系统总长很短，体积紧凑。工作时，系统高度与12x光学系统的实际焦距之比可以为0.6，关机时，系统高度与12x光学系统的实际焦距之比可以仅为0.4。
不仅如此，用于控制光学系统对焦以及镜筒收缩的控制系统设计简洁，仅通过一个电机即可实现。
在本申请实施例中，作为操作机构的另一种可选的实施方式，操作机构可以包括：滑动轨道、反射元件和电机。其中，滑动轨道中的包括位于第一入射光的透射光路上的第一区段，以及，位于第二入射光的透射光路上的第二区段。反射元件可用于在电机的驱动下沿滑动轨道移动至第一区段或者第二区段，其中，位于第一区段的反射元件用于阻挡第一 入射光沿第一入射光的透射光路到达反射镜，位于第二区段的反射元件位于第一入射光的透射光路之外，位于第二区段的反射元件用于允许第二入射光到达感光元件。需要说明的是，在实际应用中，也可以仅利用进入入光口的部分入射光进行对焦作业，在一示例中，反射镜可以将部分第一入射光反射至第一区域，以使反射元件将到达第一区域的部分第一入射光反射至感光元件，而不需要将全部第一入射光反射至感光元件。采用这种方式，第一区域可以设置较小，光学成像系统占用的空间更小。

实施例七
本申请实施例还提供一种光学成像系统。与图11所示光学成像系统不同之处在于，在本申请实施例中，反射镜81可包括：第一凹面部和第二凹面部；反射元件33可包括：第一反射部和第二反射部，其中，在所述第二状态，所述第一反射部位于第一目标区域，所述第二反射部位于第二目标区域。
图16为本申请实施例提供的光学成像系统中第一光路为折反式光路的结构示意图三。
如图16所示，在本申请实施例中，所述第一凹面部，用于将所述第一入射光反射至所述第一目标区域；所述第一反射部，用于将到达所述第一目标区域的所述第一入射光反射至所述第二凹面部；所述第二凹面部，用于将经过所述第一反射部反射的所述第一入射光反射至所述第二目标区域；所述第二反射部，用于将到达所述第二目标区域的所述第一入射光反射至所述感光元件。
采用这种折反式光路，第一光路的光程相比于图4和图12所示的第一光路更长，因此，光学成像系统在进行对焦作业时支持的最大焦距更长，也即系统支持的对焦调节范围更大。像距调节范围更大。
实施例八
本申请实施例还提供一种电子设备。在本申请实施例中，电子设备可以包括前述任一实施例中的光学成像系统以及电子设备本体。其中，光学成像系统设置于所述本体上。
作为一种示例，电子设备的本体可以设置前置入光口和后置入光口。后置入光口位于电子设备具有显示屏的一侧，前置入光口可位于背离显示屏的一侧。
本申请实施例提供的光学成像系统可作为于纯光学相机和数码相机等拍摄装置中的长焦变焦镜头使用。长焦变焦镜头在日常摄影中的使用频率很高。相比于广角镜头，使用长焦变焦镜头时构图细致不杂乱，更重要的是，使用长焦变焦镜头可以让用户在不靠近拍摄对象的情况下进行创作，对于旅行摄影与人文抓拍有着不可替代的作用。本申请实施例提供的光学成像系统通过采用支持折反式光路的设计增长系统内光程和支持的焦段，能够支持长焦和大光圈特性，同时，光学成像系统还具有体积小巧便携性高的优势。
本申请实施例的其他技术方案细节和技术效果可参见本申请其他实施例中的描述。
在上述实施例中，可以全部或部分地通过软件、硬件、固件或者其任意组合来实现。当使用软件实现时，可以全部或部分地以计算机程序产品的形式实现。计算机程序产品包括一个或多个计算机指令。在计算机上加载和执行计算机程序指令时，全部或部分地产生按照本申请的流程或功能。计算机可以是通用计算机、专用计算机、计算机网络、或者其他可编程装置。计算机指令可以存储在计算机可读存储介质中，或者从一个计算机可读存储介质向另一个计算机可读存储介质传输，例如，计算机指令可以从一个网站站点、计算机、服务器或数据中心通过有线(例如同轴电缆、光纤、数字用户线)或无线(例如红外、无线、微波等)方式向另一个网站站点、计算机、服务器或数据中心进行传输。计算机可读存储介质可以是计算机能够存取的任何可用介质或者是包含一个或多个可用介质集成的服务器、数据中心等数据存储设备。可用介质可以是磁性介质，(例如，软盘、硬盘、磁带)、光介质(例如，DVD)、或者半导体介质(例如固态硬盘Solid State Disk)等。
