请参阅图1-图3，图1是本申请实施方式的摄像头的结构分解示意图，图2是本申请实施方式的摄像头的第二滤光片位于镜头光轴上的结构示意图，图3是本申请实施方式的摄像头的第二滤光片偏离镜头光轴的结构示意图。
本申请实施方式的摄像头100，包括镜头10、图像传感器20、第一滤光片30和第二滤光片40；图像传感器20设置在镜头10的像侧；第一滤光片30设置在镜头10的光轴101上，第一滤光片30能够使紫外线和可见光通过；第二滤光片40能够使紫外线通过，第二滤光片40能够运动至位于镜头10的光轴101上或偏离镜头10的光轴101之间运动。
本申请实施方式的摄像头100设置有能够使紫外线和可见光通过的第一滤光片30，和能够使紫外线通过的第二滤光片40，第二滤光片40在镜头10的光轴101外时，物体反射的光源中的紫外线与可见光均可经过滤波后进入图像传感器20，第二滤光片40在镜头10的光轴101上时，物体反射的光源中的紫外线可进入图像传感器20，从而提高摄像头100的成像光谱范围，实现超光谱成像。
具体地，在摄像头100中，镜头10可位于摄像头100靠近拍摄物体的一侧。图像传感器20可设置在镜头10远离拍摄物体的一端与柔性电路板连接，即图像传感器20位于镜头10用于成像的一侧。镜头10上可设置有镜片11，镜片11可用于汇聚物体反射的光线，镜片11的数量可以是多个，多个镜片11可以组成镜片组。第一滤光片30可设置在镜头10的光轴101上，并可位于镜头10靠近图像传感器20的一侧。镜头10的光轴101可以是镜头10通过光线的中心轴线。第一滤光片30可设置在镜头10内的支架12上，支架12可靠近图像传感器20一侧。
第一滤光片30可以是红外截止滤波片，可用于截止物体反射进入镜头10中的红外光等除紫外线和可见光之外的其他光线。
第二滤光片40也可以是红外截止滤波片，第二滤光片40可以将物体反射进入镜头10中的除紫外线以外的其他光线进行滤波。第二滤光片40可位于镜头10光轴101上，可设置在第一滤光片30与镜片11之间的镜头10的光路轴线上，第二滤光片40也可以相对镜头10的光轴101进行运动使得第二滤光片40相对镜头10偏离镜头10的光轴101。
可以理解，当第二滤光片40位于镜头10的光轴101上时，第一滤光片30与第二滤光片40可以共同作用使得物体反射的光线进入镜头10滤波为紫外线后进入图像传感器20进行成像。当需要进行超光谱成像时，超光谱可以理解为比可见光范围更大的光谱。调节第二滤光片40偏离镜头10的光轴101，物体反射的光线将被滤波为紫外线和可见光的进入图像传感器20成像。
在某些实施方式中，第一滤光片30在紫外线的带通波段和可见光的带通波段均连续；或，
第一滤光片30在紫外线的带通波段断续，在可见光的带通波段连续。
如此，第一滤光片30中采用连续的带通波段或者断续的带通波段均可使得第一滤光片30具有紫外线通道以及可见光通道。
具体地，第一滤光片30可以是将滤波范围为400nm-700nm的短波红外截止滤波片进行改进形成的具有紫外线与可见光的连续带通波段的滤光片。可以理解，第一滤光片30可以在紫外线与可见光的波段进行连续的过渡，即滤波范围是连续无间断的波段。
请参阅图4和图5，图4是相关技术中的短波红外截止滤波片通过的光线的波长与透过率的示意图，图5是本申请实施方式的第一滤光片通过的光线的波长与透过率的示意图。短波红外截止滤波片通过的光线的波长与透过率可如图4所示。第一滤光片30通过的光线经过多层沉积后可将滤波范围扩展至超光谱范围，例如360nm-700nm，第一滤光片30通过的光线的波长与透过率可如图5所示。
或者，第一滤光片30也可以采用双通道的短红外截止滤波片，双通道的短红外截止滤波片中可具有紫外线带通波段以及可见光带通波段，且紫外线带通波段为断续。请参阅图6，图6是本申请实施方式的采用双通道的第一滤光片通过的光线的波长与透过率示意图。如图6中所示，横坐标为光线波长，纵坐标为光线透过率，在300nm-400nm之间的紫外线带通波段为断续，在400nm-700nm之间的可见光带通波段外连续。
在某些实施方式中，第一滤光片30供通过光线的波段为360nm-700nm。
如此，第一滤光片30供通过光线的波段为360nm-700nm，可以满足摄像头100对超光谱成像的需要。
具体地，第一滤光片30可供物体反射至镜头10的光线中波长为360nm-700nm的可见光光线通过，同时将其他波长的光线进行截止。
请参阅图1-图3，在某些实施方式中，在第二滤光片40能够在位于镜头10的光轴101上的情况下，第二滤光片40位于镜头10的物侧。
如此，第二滤光片40在镜头10光轴101上且位于镜头10的物侧时可以将物体反射的光线在进入摄像头100的图像传感器20之前进行滤光。
具体地，第二滤光片40可设置在镜头10的物侧，第二滤光片40可设置在镜片11与第一滤光片30之间，第二滤光片40与镜片11同轴设置并位于镜头10的光轴101上。第二滤光片40可覆盖住镜头10光轴101的进光区域。
在某些实施方式中，第二滤光片40供通过光线的波段为360nm-380nm。
如此，第二滤光片40供通过光线的波段为360nm-380nm，可以满足摄像头100对紫外线成像的需要。
具体地，当摄像头100拍摄的物体反射的光线进入镜头10时，第二滤光片40可供光线的波长为360nm-380nm的紫外光线通过，并将其他波长的光线进行截止。
请参阅图1-图3，在某些实施方式中，摄像头100包括与第二滤光片40连接的驱动部件50，驱动部件50用于驱动第二滤光片40绕转动轴线511转动以在位于镜头10的光轴101上和偏离镜头10的光轴101之间运动，转动轴线511与镜头的光轴101平行。
如此，驱动部件50的设置可以用来驱动第二滤光片40在镜头10的光轴101上或偏离镜头10光轴101，从而使摄像头100能够实现对进入镜头10的光线进行不同波段过滤的调节切换。
具体地，驱动部件50可以通过压电马达、电磁马达等装置来驱动第二滤光片40，驱动部件50还可以包括转动件51，转动件51一端可连接在镜头10上，一端可连接第二滤光片40。例如，当驱动部件50采用电磁驱动器进行驱动时，磁体可设置在转动件51上，电磁驱动器可设置在镜头10上，通过电磁驱动器驱动磁体可使转动件51绕转动轴线511进行转动，转动轴线511可以是转动件51的转轴中心线，且转动轴线511与镜头10的光轴101呈平行。转动方式可以是转动件51沿转动件51的转动轴线511平行于镜头10的方式进行移动，进而带动第二滤光片40进行平转，使得第二滤光片40处于镜头10光轴101上，或者移动至偏离镜头10的光轴101。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“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，也可以是电连接或可以相互通讯；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或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
请参阅图7并结合图1-图3，图7是本申请实施方式的摄像头的某一视角的结构示意图。在某些实施方式中，摄像头100包括补光灯60，补光灯60用于为摄像头100补光，补光灯60能够发出紫外光和可见光。
如此，补光灯60通过发出可见光和紫外光向摄像头100的拍摄的物体进行补光可以提升摄像头100对拍摄物体的成像效果，补光灯60通过发出紫外光配合第二滤光片40可以激发物体产生紫外反射，从而使摄像头100实现荧光成像。
具体地，补光灯60可设置在摄像头100上的镜头10的导光结构70上，导光结构70可以是中间设置有与镜头10的光轴101匹配的通孔的环形结构。补光灯60的数量可以是两个，两个补光灯60可设置在导光结构70的两侧端部。补光灯60的规格可以相同，补光灯60的类型可以是侧方光LED。补光灯60可以单独发出可见光或者单独发出紫外光，也可以同时发出可见光与紫外光的超光谱光。导光结构70的作用是将补光灯60的入射光线进行均匀处理，可以使得补光灯60发出的光线可以在摄像头100拍摄的物体表面上均匀照亮。请参阅图8，图8是本申请实施方式的摄像头开启补光灯时拍摄得到的图像强度分布图。从图8中可以看出，通过补光灯60均匀补光下，摄像头100拍摄得到的图像的强度为均匀分分布，强度涨落为零。需要理解的是，图8中的横坐标表示像素，纵坐标表示像素位置。
请参阅图9和图10，图9是本申请实施方式的摄像头的补光灯开启可见光和紫外光时的照明光谱图，图10是本申请实施方式的摄像头的补光灯开启紫外光时的照明光谱图。当摄像头100进行超光谱成像时，补光灯60可同时发出紫外光和可见光，照明光谱可如图9所示，只有在特定波段具有强度分布，其他波段均为零。或者单独发出紫外光，照明光谱可如图10所示，只有在特定波段具有强度分布，其他波段均为零。此时，驱动部件50可将第二滤光片40驱动至镜头10的光轴101的正向方向上并对摄像头100拍摄物体反射的入射光线进行滤波处理，由于镜头10内还具有第一滤光片30，但第一滤光片30的供通过光线的波段要大于第二滤光片40，因此，最终图像传感器20接收的波段由第二滤光片40所决定，当完成超光谱成像时，驱动部件50将驱动第二滤光片40偏离至镜头10的光轴101外。
当摄像头100进行荧光成像时，补光灯60可同时发出紫外光和可见光，照明光谱可如图9所示，只有在特定波段具有强度分布，其他波段均为零，超光谱光源投射到物体表面后会刺激物体产生相应的荧光，该荧光由于斯托克斯位移，波长不再是超光谱而是可见光波长。此时，驱动部件50可将第二滤光片40驱动偏离至镜头10的光轴101外，由于镜头10内还具有第一滤光片30，第一滤光片30的供通过光线的波段为360nm-700nm。
因此，最终图像传感器20接收的波段由物体产生的荧光光源(波段为400-770nm)以及第一滤光片30过滤的光源(360nm-700nm)的卷积所决定，吸收波段为400-700nm，图像传感器20可以很好的接收由补光灯60发出的超光谱激发的荧光，并且避免了超光谱反射光的影响。
当摄像头100进行可见光成像时，补光灯60可单独发出可见光，可见光的光源只有在 400nm-700nm左右具有强度分布，其他波段均为零。此时，驱动部件50可将第二滤光片40驱动偏离至镜头10的光轴101外，由于镜头10内还具有第一滤光片30，第一滤光片30的供通过光线的波段为360nm-700nm。
因此，最终图像传感器20接收的波段由物体产生的可见光光源(波段为400-700nm)以及第一滤光片30过滤的光源(360nm-700nm)的卷积所决定，吸收波段为400-700nm，图像传感器20可以很好的接收由被物体反射的可见光，从而实现清晰成像。
请参阅图11和图12，图11是本申请实施方式的摄像头处于第一模式的平面示意图，图12是本申请实施方式的摄像头处于第二模式的平面示意图。在某些实施方式中，镜头10具有第一模式和第二模式，镜头10位于第一模式时具有第一对焦物距，镜头10位于第二模式时具有第二对焦物距，第一对焦物距小于第二对焦物距。
如此，镜头10通过第一模式可以对物体进行第一对焦物距的拍摄，通过第二模式可以对物体进行第二对焦物距的拍摄，可以提升用户使用摄像头100在不同对焦物距场景下的拍摄需求。
具体地，镜头10内可通过马达等驱动装置驱动镜头10内的镜片11或镜片组进行移动，使得镜片组可以使镜头10在对焦物距为第一对焦物距和第二对焦物距之间切换，从而使得镜头10在第一模式和第二模式之间切换。
请参阅图11和图12，在某些实施方式中，第一对焦物距小于或等于10mm，和/或，第二对焦物距小于或等于50mm。
如此，第一对焦物距小于或等于10mm可以实现摄像头100与物体处于显微状态下的拍摄，第二对焦物距小于或等于50mm可实现摄像头100在微距模式下的拍摄。
具体地，第一模式可以是镜头10与物体平面之间的第一对焦物距D1小于10mm的显微距离，例如，D1可以是5mm的显微距离。从而使离镜头10显微距离的物体平面透过镜头10在图像传感器20上实现清晰成像。
进一步地，第二模式可以是镜头10与物体平面之间的第二对焦物距D2大于10mm的距离，例如，D2可以是30mm的微距距离。从而使离镜头10微距距离的物体透过镜头10在图像传感器20上实现清晰成像。
需要理解的是，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个所述特征。在本申请的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
请参阅图13，图13是本申请实施方式的电子装置的结构示意图。本申请实施方式的电子装置1000，包括上述任一项实施方式的摄像头100。
本申请的电子装置1000采用摄像头100能够实现进行紫外线图像和荧光图像的获取，电子装置1000也可以用来进行皮肤检测和真伪识别等功能，提升了电子装置1000拍照时的体验。
具体地，电子装置1000可以是具有拍照功能的终端设备。例如，电子装置1000可以包括智能手机、平板、电脑、数码相机或其他具有拍照功能的终端设备。摄像头100可设置在电子装置1000上，例如，手机的后置摄像头100，数码相机的摄像头100等。
综上所述，当电子装置1000通过摄像头100进行第一模式的显微拍摄时，可通过摄像头100实现对拍摄物体的荧光显微成像、超光谱显微成像和可见光显微成像。
请参阅图14，图14是本申请实施方式的电子装置通过摄像头进行第一模式的可见光显微拍摄的成像图。如图14所示，当电子装置1000通过摄像头100进行第一模式的可见光显微成像拍摄时，由于被拍摄物体对可见光无反射，因此不能得到任何有效信息。
请参阅图15并结合图1-图3，以及图7，图15是本申请实施方式的电子装置通过摄像头进行第一模式的超光谱显微拍摄的成像图。当电子装置1000通过摄像头100进行第一模式的超光谱显微成像拍摄时，补光灯60可同时发出可见光与紫外光，驱动部件50可驱动第二滤光片40位于镜头10的光轴101上，图像传感器20可接收由补光灯60激发出来并由物体反射的紫外线图像；
请参阅图16，图16是本申请实施方式的电子装置通过摄像头进行第一模式的荧光显微拍摄的成像图。如图16所示，当电子装置1000通过摄像头100进行第一模式的荧光显微成像拍摄时，补光灯60可同时发出可见光与紫外光或者单独发出紫外光，驱动部件50可驱动第二滤光片40位于镜头10的光轴101上，图像传感器20可接收由补光灯60激发出来的物体反射的荧光图像；
电子装置1000通过摄像头100还可以用于对皮肤深层次的探测。请参阅图17和图18，如图17为电子装置1000通过摄像头100在第一模式下拍摄的人脸的可见光成像图片，图18为电子装置1000通过摄像头100在第一模式下拍摄的人脸的紫外线成像图片，通过对比可以检测分析出人脸面部的水油平衡，和其他皮肤问题。
