光路准直是光学领域中的一个很重要的参数。通常来说，从同一个光源所发出的光线是发散的，即开始相邻的两条光线传播后会相离越来越远，而光路准直通俗说就是通给一定的手段保持光线之间平行。在进行光学实验或光学应用时，一般需要通过光学镜架来对光线进行调整，以实现光路准直。

具体实施方式
图1示例性示出了本申请实施例提供的一种光学镜架的结构示意图。如图1所示，光学镜架1可以包括镜架座11和多个控制件，例如图1中示出的控制件12和控制件13。其中，每个控制件(控制件12或控制件13)的一端可以与镜架座11固定连接，另一端可以与光学镜片2固定连接。例如，图1中示出的控制件12的一端121可以与镜架座11固定连接，另一端122可以与光学镜片2固定连接，控制件13的一端131可以与镜架座11固定连接，另一端132可以与光学镜片2固定连接。
进一步地，镜架座11可以包括透光区111，便于光线通过透光区111射入光学镜片2。
如图1所示，每个控制件的内部可以设置有调温件。例如，控制件12的内部可以设置有调温件123，控制件13的内部可以设置有调温件133。
更进一步地，调温件可以包括调温主体，例如，调温件123可以包括调温主体1231，调温主体1231可以与外部电子元件(图1中未示出)电连接，并且可以根据外部电子元件的调节来改变自身的温度，从而可以以传热的方式调节控制件12的温度，进而可以调节控制件12的形变；类似地，调温件133可以包括调温主体1331，调温主体1331可以与外部电子元件电连接，并且可以通过外部电子元件来调节自身的温度，从而可以以传热的方式调节控制件13的温度，进而可以调节控制件13的形变。
采用本申请实施例提供的光学镜架，由于与光学镜片连接的控制件中设置有调温件，因此可以通过调温件的温度变化来调节控制件的温度，根据热胀冷缩的原理，控制件温度的变化与控制件的形变存在相关关系，即可以调节控制件的形变，从而可以调整光学镜片的位置，进而可以提高光线的准直度，大大提高了整个光学系统的性能。
本申请实施例中，镜架座11的形状可以有多种，比如，镜架座11可以是“L”形，或者也可以是“凹”形，或者也可以是其它形状，具体不做限定。图1中示出的镜架座11就是“凹”形的。
进一步地，镜架座11的形状也会影响到透光区111的形状。举个例子，以“L”形镜架座11为例，对应的透光区111的形状也为L形。再举个例子，若镜架座11的形状为“凹”形，则对应的透光区111的形状可以为“U”形。
作为一种示例，图2提供了另外一种镜架座11可能的形状。如图2所示，为本申请实施例提供的另一种光学镜架的结构示意图。镜架座11可以包括支撑壁112，其中，支撑壁112可以垂直于水平面。那么，透光区111可以为设置在支撑壁112上的通孔，且，该通孔的轴线(图2中示出的L轴)可以垂直于支撑壁112所处的平面。进一步地，如图2所示，每个控制件(控制件12或控制件13或控制件14)与通孔的圆心(图2中示出的O点)之间的距离一致。采用图2示出的结构，光学镜架的整体结构简单，便于模具开料，也有利于大规模生产。
本申请实施例中，支撑壁112的形状可以有多种，可以为图2中示出的带圆弧的板形，或者也可以为矩形，或者还可以为其它形状，本领域技术人员可以根据实际情况设计支撑壁112的形状，具体不做限定。相应地，图2中示出的通孔(即透光区111)可以为多种形状的通孔，比如，可以为圆形，或者可以为矩形，或者还可以为不规则形，具体不做限 定。
需要说明的是，支撑壁112的底部可以直接作为镜架座11的底座，或者，镜架座11也可以额外设置有底座，具体不做限定。
进一步地，如图2所示，光学镜片2的轴线(图2中示出的L’轴)与通孔(及透光区111)的轴线在同一条直线上。如此，可以保证从透光区111的中心射出的光线可以从光学镜片2的中心射入，从而提高光线的准直度。
进一步地，图2示出的光学镜架可以包括三个控制件，分别是图2中示出的控制件12、控制件13和控制件14。采用三个控制件的结构，一方面，能够保证光学镜架1的整体结构的稳定性，另一方面，可以利用三点调整来提高调节控制件的形变的准确度，实现精准的动态三维调节。
更进一步地，如图2所示，任意两个相邻的控制件之间的距离一致，例如，控制件12与控制件13之间的距离和控制件13与控制件14之间的距离是一致的，控制件12与控制件13之间的距离和控制件12与控制件14之间的距离也是一致的。如此，能确保光学镜架1的整体受力是均匀的，提高结构稳定性。
本申请实施例中，控制件的形状可以由多种，比如，控制件12(或控制件13或控制件14)可以为圆柱形，或者也可以为四棱柱形，或者还可以为三棱柱形，或者还可以为不规则的立体图形，具体不做限定。
下面具体介绍控制件的结构，以控制件12为例，图3a示例性示出了本申请实施例提供的一种控制件的结构示意图。如图3a示，控制件12内部可以设置有调温件123，其中，调温件123可以包括调温主体1231和电线1232。具体地，调温主体1231的一端(如图3a示出的A端)可以伸入控制件12的内部，另一端(如图3a示出的B端)可以与控制件12的端部(如图3a示出的C端)齐平。其中，控制件12的端部可以是指图1中示出的控制件12与镜架座11固定连接的端部(即图1中示出的控制件12的一端121)。进一步地，电线1232可以与调温主体1231的另一端(如图3a示出的B端)电连接。
在另一种可能的示例中，如图3b所示，为本申请实施例提供的另一种控制件的结构示意图。仍然以控制件12为例，控制件12内部可以设置有调温件123，其中，调温件123可以包括调温主体1231和电线1232。具体地，调温主体1231的一端(如图3b示出的A端)可以伸入控制件12的内部，另一端(如图3b示出的B端)可以凸出于控制件12的端部(如图3b示出的C端)。其中，控制件12的端部可以是指图1中示出的控制件12与镜架座11固定连接的端部(即图1中示出的控制件12的一端121)。进一步地，电线1232可以与调温主体1231的另一端(如图3b示出的B端)电连接。
需要说明的是，以控制件12为例，调温主体1231与外部电子元件的电连接的方式有多种，可以是如图3a或图3b中示出的通过电线实现电连接，或者也可以采用电磁连接的方式实现电连接，具体不做限定。
为了更加完整地介绍本申请实施例提供的光学镜架1，下面将以图3b中示出的控制件为例，具体描述包括图3b示出的控制件12的光学镜架1的结构。
图4示例性示出了本申请实施例提供的光学镜架的整体性的结构示意图。如图4所示，光学镜架1可以包括镜架座11、控制件12、控制件13和控制件14。其中，镜架座11上可以设置有多个控制件一一对应的多个过线孔，例如图4中示出的，镜架座11上设置有 与控制件12对应的过线孔113，与控制件13对应的过线孔114以及与控制件14对应的过线孔115。控制件12的一端在过线孔113所处的位置与镜架座11固定连接，另一端与光学镜片2固定连接；控制件13的一端在过线孔114所处的位置与镜架座11固定连接，另一端与光学镜片2固定连接；控制件14的一端在过线孔115所处的位置与镜架座11固定连接，另一端与光学镜片2固定连接。
控制件12的内部设置有调温件123，调温件123可以包括调温主体1231和与调温主体1231电连接的电线1232，电线1232穿过过线孔113与外部电子元件3电连接；控制件13的内部设置有调温件133，调温件133可以包括调温主体1331和与调温主体1331电连接的电线1332，电线1332穿过过线孔114与外部电子元件3电连接；控制件14的内部设置有调温件143，调温件143可以包括调温主体1431和与调温主体1431电连接的电线1432，电线1432穿过过线孔115与外部电子元件3电连接。
进一步地，调温主体1231的另一端凸出于控制件12的端部时，调温主体1231凸出于控制件12的端部的部分与过线孔113相吻合；相应地，调温主体1331的另一端凸出于控制件13的端部时，调温主体1331凸出于控制件13的端部的部分与过线孔114相吻合；调温主体1431的另一端凸出于控制件14的端部时，调温主体1431凸出于控制件14的端部的部分与过线孔115相吻合。
如此，调温件123可以通过外部电子元件3来调节自身的温度，从而可以以传热的方式调节控制件12的温度，进而可以调节控制件12的形变；调温件133可以通过外部电子元件3来调节自身的温度，从而可以以传热的方式调节控制件13的温度，进而可以调节控制件13的形变；调温件143可以通过外部电子元件3来调节自身的温度，从而可以以传热的方式调节控制件14的温度，进而可以调节控制件14的形变。
本申请实施例中，每个控制件(如上文提及的控制件12或控制件13或控制件14)与镜架座11固定连接的方式有多种，比如可以是焊接、螺栓连接、胶接等，具体不做限定。
类似地，每个控制件(如上文提及的控制件12或控制件13或控制件14)与光学镜片2固定连接的方式有多种，比如可以通过柔性胶固定连接，或者可以通过螺栓固定连接，具体不做限定。
本申请实施例中，控制件(如上文提及的控制件12或控制件13或控制件14)可以为多种类型的材料，举个例子，控制件(如上文提及的控制件12或控制件13或控制件14)可以为金属，比如为高纯度高密度的铜棒，由于金属受热之后会线性膨胀，因此，采用金属制成的控制件能够通过精准控制调温件的温度来实现精准的长度控制。在其它可能的实例中，控制件(如上文提及的控制件12或控制件13或控制件14)也可以为高分子材料，具体不做限定。
基于同样的构思，图5示例性示出了本申请实施例提供的一种光学镜架的调节系统的结构示意图。如图5所述，调节系统4可以包括至少一个光学镜架1、检测装置41和调节装置42。其中，检测装置41可以设置于任一光学镜架1的光线出口处，比如图5示出的结构中检测装置41可以设置于沿着光线发射方向最末端的光学镜架1的光线出口处，可以用于检测从该光学镜架中射出的光线是否准直。调节装置42可以与检测装置电连接，且与每个光学镜架电连接，可以用于根据检测装置41的检测结果调节光学镜架1中调温件的温度，从而可以以传热的方式调节光学镜架中控制件的温度，进而可以调节控制件的 形变。
采用本申请实施例提供的光学镜架的调节系统，调节装置可以根据检测装置检测从光学镜架中射出的光线是否准直，来确定是否需要对光学镜架中光学镜片的位置进行调整，以及如何调整，进而调节装置可以通过改变光学镜架中调温件的温度来调节控制件的温度，根据热胀冷缩的原理，控制件温度的变化与控制件的形变存在相关关系，即可以调节控制件的形变，从而可以调整光学镜片的位置，进而可以提高光线的准直度，大大提高了整个光学系统的性能。
本申请实施例中，检测装置41可以检测多种类型的数据，比如，检测装置41可以直接检测光路准直度，或者检测装置41也可以通过检测功率变化来确定光路是否准直，具体不做限定。
需要说明的是：(1)图5仅为一种光学镜架的调节系统的示例，在其它可能的实例中，调节系统4也可以包括多个检测装置41，且，每个检测装置41可以对应设置于光学镜架的光线出口处；(2)图5中示出的调节装置42可以看做是上文提及的外部电子元件3。
本申请提供的实施例之间的相似部分相互参见即可，以上提供的具体实施方式只是本申请总的构思下的几个示例，并不构成本申请保护范围的限定。对于本领域的技术人员而言，在不付出创造性劳动的前提下依据本申请方案所扩展出的任何其他实施方式都属于本申请的保护范围。
