具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。通常在此处附图中描述和示出的本发明实施例的组件 可以以各种不同的配置来布置和设计。
因此，以下对在附图中提供的本发明的实施例的详细描述并非旨在限制要求保护的本发明的范围，而是仅仅表示本发明的选定实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步定义和解释。
在本发明的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，或者是该发明产品使用时惯常摆放的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，术语“第一”、“第二”、“第三”等仅用于区分描述，而不能理解为指示或暗示相对重要性。
此外，术语“水平”、“竖直”等术语并不表示要求部件绝对水平或悬垂，而是可以稍微倾斜。如“水平”仅仅是指其方向相对“竖直”而言更加水平，并不是表示该结构一定要完全水平，而是可以稍微倾斜。
在本发明的描述中，还需要说明的是，除非另有明确的规定和限定，术语“设置”、“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
请参照图1，本实施例提供一种光学模组，该光学模组包括沿主 光轴方向依次设置的扩束镜10、准直镜20以及聚焦镜组30；光束经扩束镜10扩束后入射至准直镜20，准直镜20将光束准直后通过聚焦镜组30聚焦后出射。该光学模组的光路结构具有通用性，能够同时兼容微透镜阵列组匀化塑形和光波导匀化塑形。
上述扩束镜10、准直镜20和聚焦镜组30沿主光轴的方向依次设置，如图1所示。其中，扩束镜10用于对光源出射的光束进行光束扩束。
准直镜20位于扩束镜10的出光侧，用于对扩束镜10扩束后的光束进行准直处理，如图1所示，这样，便可以得到准直光束。
聚焦镜组30设于准直镜20的出光侧，用于将经准直镜20准直后的准直光束进行聚焦，从而使得能够在接收面得到聚焦后的光斑。
需要说明的是，当采用光波导对光束进行匀化塑性时，可以将该光波导设置于扩束镜10的入光侧，这样，经过光波导匀化后的光束能够在扩束镜10、准直镜20和聚焦镜组30的作用下在接收面得到匀化后的光斑；当采用微透镜阵列对光束进行匀化时，可以将该微透镜阵列设置于准直镜20的出光侧和聚焦镜组30的入光侧，这样，也能够起到对光束的匀化塑形作用。
本申请提供的光学模组由于其在光源的出光侧设置了扩束镜10，且在聚焦镜组30和扩束镜10之间又设置了对应的准直镜20，因此，其光路结构既能够实现与光波导的配合，实现采用光波导进行匀化塑形的需求；又能够实现与微透镜阵列的配合，实现采用微透镜阵列进行匀化塑形的需求。这样，相对于现有技术中，对于采用光波导进行匀化塑形而言必须单独设计一种适用于其的基础光路结构，采用微透镜阵列进行匀化塑形时又得单独设计一种适用于微透镜阵列的基础光路结构来说，本申请提供的光学模组既能够作为光波导匀化的基础光路结构，也可以作为微透镜阵列的基础光路结构，这样，用 户只需要根据需要对应替换匀化组件即可，其基础光路结构无需额外设计，能够极大的降低生产成本和工作效率，具有较佳的应用前景。
综上所述，本申请提供的光学模组包括沿主光轴方向依次设置的扩束镜10、准直镜20以及聚焦镜组30；光束经扩束镜10扩束后入射至准直镜20，准直镜20将光束准直后通过聚焦镜组30聚焦后出射。采用本申请提供的光学模组时，当需要采用光波导对光束进行匀化时，可以将光波导设置于该光学模组的扩束镜10的入光侧，这样，光波导能够对光束进行匀化塑形，匀化塑性后再通过扩束镜10的扩束、准直镜20的准直和聚焦镜组30的聚焦后在接收面能够得到均匀的聚焦光斑；而当需要采用微透镜阵列对光束进行匀化时，可以将微透镜阵列设置于准直镜20和聚焦镜组30之间，这样，微透镜阵列能够对经扩束镜10扩束后的光束进行匀化处理，从而再通过聚焦镜组30聚焦后在接收面得到均匀的聚焦光斑。如此，本申请提供的光学模组既能够作为光波导的基础光路结构，也可以作为微透镜阵列的基础光路结构，使得两种匀化方式均能够适用于该光学模组中，这样，用户采用光波导匀化或者采用微透镜阵列匀化时，该光学模组的结构都能够适用，具有较高的兼容性，相对现有技术中不同的匀化方式必须设计各自对应的基础光路结构而言，本申请的光学模组因其较高的兼容性和通用性，能够极大地降低设计成本和生产成本，具有较佳的应用前景。
如图1所示，可选地，上述扩束镜10为平凹透镜，且平凹透镜的平面一侧朝向准直镜20，平凹透镜的凹面一侧背向准直镜20。
另外，可选地，准直镜20为第一平凸透镜，第一平凸透镜的平面朝向扩束镜10，第一平凸透镜的凸面朝向聚焦镜组30。
应理解，上述扩束镜10的类型和准直镜20的类型仅为本申请给出的一种示例，并非是对本申请的限制，在其他的实施例中，本领域 技术人员还可以根据需要选择其他类型的光学元件作为扩束镜10和准直镜20，只要能起到扩束和准直的作用即可。
但同时，需要说明的是，本申请选用平凹透镜作为扩束镜10，采用第一平凸透镜作为准直镜20，这样，平凸透镜作为正透镜，平凹透镜作为负透镜，两者的球差一个为负球差一个为正球差，如此，能使得该光学模组的正负球差至少部分相抵，进而能够部分消除球差和惠差。
还有，如图1所示，在本实施例中，上述聚焦镜组30包括依次设置的第一弯月透镜31和第二弯月透镜32，第一弯月透镜31的凸面朝向准直镜20，第一弯月透镜31的凹面朝向第二弯月透镜32的凸面。
即第一弯月透镜31和第二弯月透镜32的凸面均朝向准直镜20，而第一弯月透镜31和第二弯月透镜32的凹面均背向准直镜20。
本申请将聚焦镜组30设置为两个弯月透镜，将扩束镜10设置为平凹透镜，将准直镜20设置为平凸透镜，这样，多个透镜相互配合并对应调整各自的曲率能够校正球差和惠差，使得该光学模组的球差和惠差降低至较低值，从而在接收面得到高聚焦几乎无离散的均匀光斑。
为了对该光学模组的各光学元件进行保护，从而提高光学模组的使用寿命，在本实施例中，可选地，光学模组还包括设于聚焦镜组30出光侧的保护窗40，自聚焦镜组30出射的光束能够透过保护窗40出射。
该保护窗40可以为透光的玻璃。具体的，该保护窗40的具体材料本申请不做特别限制，本领域技术人员可以根据需要自行选择合适材料。

耦合镜组52位于光纤输出光源51的出光侧，其用于将光纤输出光源51出射的光束耦合至多边形光波导53内。多边形光波导53用于对进入其内的光束进行匀化处理。
示例性地，该多边形光波导53的形状和尺寸本领域技术人员可以自行设置，本申请不做限制。例如，该多边形光波导53的形状可以为四边形。
另外，在本实施例中，该多边形光纤可以包括多个，且该多个多边形光纤的规格各不相同，这样，用户可以根据所需光斑的大小和形状需要选择合适规格的多边形光纤使用。
需要说明的是，上述规格可以为形状，也可以为尺寸，也可以为形状和尺寸。
本申请通过光纤输出光源51、耦合镜组52、多边形光波导53、扩束镜10、准直镜20以及聚焦镜组30的组合可以实现输出任意形状的光束的光源(即光纤输出光源51)向多边形光斑的转换；还可 以实现低球差和低惠差高聚焦光斑的输出，以及低相干和消相干特性。
请参照图3，可选地，耦合镜组52包括依次设置的第二平凸透镜521、第三弯月透镜522和第四弯月透镜523；第二平凸透镜521的平面朝向光纤输出光源51，且第二平凸透镜521的凸面朝向第三弯月透镜522的凸面；第三弯月透镜522的凹面朝向第四弯月透镜523的凸面。

第二平凸透镜521用于将光纤输出光源51出射的光束进行准直，第三弯月透镜522和第四弯月透镜523用于将第二平凸透镜521准直后的光束进行聚焦，以使得聚焦后的光束耦合至多边形光波导53内。
需要说明的是，上述多边形光波导53也可以为多边形光纤。
在第二种情况下，请结合图4至图8，光学模组还包括第二匀化组60，第二匀化组60设于准直镜20和聚焦镜组30之间。
示例性地，该第二匀化组60包括依次设置的第一微透镜阵列组61和第二微透镜阵列组62，第一微透镜阵列组61位于第二微透镜阵列组62和准直镜20之间。
