本申请附加的方面和优点将在下面的描述中部分给出，部分将从下面的描述中变得明显，或通过本申请的实践了解到。

如图所示：1、旋转基座，2、光调制装置，3、样本容器，4、第一反射镜，5、第二反射镜。
具体实施方式
下面详细描述本申请的实施例，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，仅用于解释本申请，而不能理解为对本申请的限制。相反，本申请的实施例包括落入所附加权利要求书的精神和内涵范围内的所有变化、修改和等同物。
图1是本申请一实施例提出的旋转式三维光激发装置的结构示意图。
参见图1，旋转式三维光激发装置包括旋转基座1、潜望镜组、光调制装置2及样本容器3。
在本实施例中，旋转基座1为长方形板体结构，其固定安装在驱动电机的旋转轴上，其旋转中心轴即与驱动电机的旋转轴重合，同时，旋转基座1的长度方向与驱动电机的旋转轴垂直，其宽度方向与驱动电机的旋转轴平行，其中，驱动电机在附图中未示出，其用 于驱动旋转基座1旋转。
光调制装置2即为光调制器，其利用光调制技术，能够将携带信息的信号叠加到载波光波上，光调制器能够使光波的某些参数如振幅、频率、相位、偏振状态和持续时间等按一定的规律发生变化，光调制装置2作为现有技术，在此不再赘述。
光调制装置2固定安装时，其光束中心轴与旋转基座1的旋转中心轴重合，其用于光束的调制。
潜望镜组安装在旋转基座1上，其光调制装置2的光束沿旋转基座1的旋转中心轴进入潜望镜组内，潜望镜组将光调制装置2的光束偏移至与旋转基座1的旋转中心轴相交处。
其中，潜望镜组包括第一反射镜4及第二反射镜5，第一反射镜4固定安装在旋转基座1上，且其与旋转基座1垂直，同时，第一反射镜4位于旋转基座1的旋转中心轴上，且其与旋转基座1的旋转轴之间存在小于90度的夹角，第二反射镜5固定安装在旋转基座1上，且其与旋转基座1垂直，同时，第二反射镜5远离旋转基座1的旋转中心轴，且其与第一反射镜4及旋转基座1的旋转轴均存在小于90度的夹角，从而在光调制装置2的光束依次经过第一反射镜4及第二反射镜5的反射后，能够与旋转基座1的旋转中心轴相交。
在一些实施例中，第二反射镜5可设置多个，以使光调制装置2的光束经多次反射后最终与旋转基座1的旋转中心轴相交。
在本实施例中，由于旋转基座1的不断旋转，使光调制装置2的部分光束无法进入到潜望镜组中，为减少该部分光束的浪费，光调制装置2根据旋转基座1的角度发射具有相应图案的光束，以提高光调制装置2发射光束的利用率。
在一些实施例中，旋转基座1的角度可通过光栅尺进行检测，光栅尺将旋转基座1的角度信号转换为电信号，以便于光调制装置2根据该电信号发射具有相应图案的光束。
在本实施例中，样本容器3相对于光调制装置2位置固定，其由透明材料制成，且其为内置空腔的箱体结构，样本置于样本容器3中。
在一些实施例中，样本容器3可由钢化玻璃、有机玻璃等材料制成，以保证样本容器3具有良好的透光性。
在本实施例中，光调制装置2的光束中心轴与旋转基座1的旋转中心轴的交点位于样本容器3内，以使光调制装置2的光束依次经过第一反射镜4及第二反射镜5的反射后能够穿过样本容器3，且随着旋转基座1的旋转，光调制装置2的光束中心轴与旋转基座1的旋转中心轴的交点在样本容器3内的位置始终不变。
从而在旋转基座1的旋转以及样本容器3固定不动的情况下，光调制装置2的光束从不同的角度照射进入样本，且不同角度不同形状的光束相叠加，以激发出三维空间中的特定三维形状，从而提升了三维光激发的效率，且样本容器3无需移动，方便更换。
如图2所示，在本实施例中，光调制装置2的光束中心轴与旋转基座1的旋转中心轴的交点位于样本容器3的中心处，从而使光调制装置2的光束在样本容器3内以该交点为中心，形成两个对称的圆锥形状组合而成的三维区域，使三维空间中的三维形状达到最大。
需要说明的是，在本申请的描述中，术语“第一”、“第二”等仅用于描述目的，而不能理解为指示或暗示相对重要性。此外，在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型。
