本申请要求于2015年10月19日提交中国专利局、申请号为201510681286.9、发明名称为“激光发射装置、激光接收装置及对战设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明实施例涉及光学结构领域，特别涉及一种激光发射装置、激光接收装置及对战设备。
背景技术
激光调制载波发射技术是一种利用激光良好的方向性和低发散角特性，进行数据传输的技术。
激光调制载波发射技术被广泛使用在设备控制领域。比如，设备A使用激光向设备B传输数据时，设备A根据需要传输的数据对激光进行调制，并通过激光发射装置向设备B发射调制后的激光。设备B通过激光接收装置接收到该激光后，对激光进行解调，即可获取该激光中携带的数据。
由于激光的方向性较好且光束较窄，导致单个激光发射装置仅能够向单一方向发射激光，且单个激光接收装置仅能够接收来自单一方向的激光。为了使设备能够同时向多个方向发射激光，且能够同时接收来自多个方向的激光，设备周侧需要设置多个激光发射装置和激光接收装置，导致设备整体能耗较高。

根据本发明实施例的第二方面，提供一种激光接收装置，该激光接收装置包括：广角反射面组件和激光接收组件，该广角反射面组件的激光出射方向与激光接收组件的激光接收方向相同；
广角反射面组件，用于将来自至少两个激光入射方向的激光反射至同一激光出射方向；
激光接收组件，用于沿激光接收方向接收广角反射面组件反射的激光。
根据本发明实施例的第三方面，提供一种对战设备，该对战设备包括：对战设备本体、设置在对战设备本体上的激光发射装置和激光接收装置；

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
图1示出了本发明一个实施例提供的激光发射装置的结构示意图。该激光发射装置包括激光发射组件110和广角反射面组件120。
其中，激光发射组件110用于沿激光发射方向向广角发射面组件120发射激光。
可选的，该激光发射组件110为激光发射管或激光发射头等等，本发明并不对激光发射组件110的类型进行限定。
如图1所示，激光发射组件110的发射端111沿激光发射方向(图1中从下至上的箭头)向广角发射面组件120的反射面121发射激光。
相应的，广角反射面组件120接收激光发射组件110沿激光发射方向发射的激光，并向至少两个激光出射方向反射该激光，从而实现单向激光同时向多个方向进行投射的效果。
如图1所示，激光发射组件110发射的激光投射在广角反射面组件120的反射面121后，即在反射面121处发生反射。图1中，该广角反射面组件120为倒置的圆锥体，激光经过反射面121(即圆锥体的锥面)反射后，分为了第一激光131和第二激光132，其中，第一激光131的激光出射方向为从右至左，而第二激光132的激光出射方向为从左至右。需要说明的是，该激光在经过反射面反射后，会沿着同一平面的各个方向出射，本实施例仅以上述两个方向进 行示意性说明，并不对本发明构成限定。
需要说明的是，本实施例仅以广角反射面组件120为倒置的圆锥体为例进行说明，在其他可能的实施方式中，该广角反射面组件120还可以为其他具有至少两个平面反射面的组件，比如呈预定夹角且对称设置的两个镜面(具有两个平面反射面)、具有三个平面反射面的正三棱锥组件、具有四个平面反射面的正四棱锥组件等等，本发明实施例并不对此构成限定。
显而易见的，设置有图1所示的激光发射装置的设备进行激光发射时，单方向的激光经过广角反射面组件反射后，可以同时向同一平面内的多个方向进行投射，即设备中仅需要设置一个激光发射组件就能实现同时向多方向发射激光，显著减少设备中激光发射组件的数量，降低设备的整体功耗。
综上所述，本实施例中，通过在激光发射组件的激光发射方向上设置具有激光反射能力的广角反射面组件，使得单一方向的激光经过广角反射面组件反射后，向多个激光出射方向射出，实现了单个激光发射装置同时向多个方向发射激光，从而减少了设备上激光发射装置的数量，降低了设备的整体功耗。
与上述激光发射装置同时向多方向发射激光的原理相反，设置有广角反射面组件的激光接收装置通过该广角反射面组件对同一平面上各个方向的激光进行反射，使得不同方向的激光均以相同的激光出射方向投射在激光接收组件上，从而实现单个激光接收装置同时接收多个方向的激光。
图2示出了本发明一个实施例提供的激光接收装置的结构示意图。该激光接收装置包括广角反射面组件210和激光接收组件220。其中，广角反射面组件210的激光出射方向与激光接收组件220的激光接收方向相同。
其中，广角反射面组件210用于将来自至少两个激光入射方向的激光反射至同一激光出射方向。
如图2所示，广角反射面组件210为倒置的圆锥体，且广角反射面组件210的反射面211位圆锥体的锥面。来自同一平面不同激光入射方向的第一激光231(激光入射方向为从左至右)和第二激光232(激光入射方向为从右至左)经过反射面211反射后，激光出射方向均变为了从上至下。相似的，该平面上其他激光入射方向上的激光经过反射面211反射后，激光出射方向均变为从上至下。
需要说明的是，本实施例仅以广角反射面组件210为倒置的圆锥体为例进 行说明，在其他可能的实施方式中，该广角反射面组件210还可以为其他具有至少两个平面反射面的组件，比如呈预定夹角且对称设置的两个镜面(具有两个平面反射面)、具有三个平面反射面的正三棱锥组件、具有四个平面反射面的正四棱锥组件等等，本发明实施例并不对此构成限定。
相应的，激光接收组件220沿激光接收方向(即广角反射面组件210的激光出射方向)接收广角反射面组件210反射的激光。
其中，该激光接收组件220可以为激光接收管或激光接收头等等，本发明并不对激光接收组件220的类型进行限定。
如图2所示，激光接收组件220通过接收端221接收激光出射方向为从上至下的激光。
显而易见的，设置有图2所示的激光接收装置的设备进行激光接收时，可以同时接收到来自同一平面各个激光入射方向的激光，即设备中仅需要设置一个激光接收装置就能实现同时接收多个方向的激光，显著减少设备中激光接收组件的数量，降低设备的整体功耗。
综上所述，本实施例中，通过在激光接收组件的激光接收方向上设置具有激光反射能力的广角反射面组件，使得沿多个激光入射方向的激光经过广角反射面组件反射后，均沿着同一激光出射方向投射在激光接收组件上，实现了单个激光接收装置同时接收多个方向入射的激光，从而减少了设备上激光接收装置的数量，降低了设备的整体功耗。
需要说明的是，上述激光发射装置和激光接收装置可以进行整合，形成激光收发装置。可选的，对这两个装置进行整合时，可以使用透明材质制作激光接收组件，并将激光发射组件设置在激光接收组件正下方，使得激光发射组件能够透过上方的激光接收组件发射激光，本发明并不对此进行限定。
为了方便将上述实施例提供的激光发射装置和激光接收装置安装到设备上，广角反射面组件和激光接收组件设置在同一腔体中，广角反射面组件和激光发射组件均设置在该腔体中，下面采用示意性实施例进行说明。
图3A示出了本发明另一实施例提供的激光发射装置的结构示意图。该激光发射装置包括腔体310，设置在腔体310内部的激光发射组件320和广角反射面组件330。
腔体310包括腔体顶面311、与腔体顶面311平行的腔体底面312以及位 于腔体顶面311和腔体底面312之间的腔体侧面313。
如图3A所示，该腔体310为圆柱体结构，圆柱体结构的圆柱顶面即为腔体顶面311，圆柱体结构的圆柱底面即为腔体310的腔体底面312，圆柱体结构的圆柱面即为腔体310的腔体侧面313。需要说明的是，本实施例仅以该腔体310为圆柱体结构为例进行说明，在其他可能的实施方式中，该腔体310也可以采用其他多面体立柱结构，本发明并不对此进行限定。
若广角反射面组件330的反射面为弧形反射面，如图3A所示，广角反射面组件330可以为圆锥结构，该圆锥结构包括圆锥底面331和圆锥面332且圆锥面332为广角反射面组件330的弧形反射面。
图3A中，广角反射面组件330的圆锥底面331与腔体顶面311固定，激光发射组件320的固定端与腔体底面312相连，且圆锥结构的顶点333正对激光发射组件320的发射端321。
为了使经过广角反射面组件330反射的激光沿同一平面不同方向出射，图3A所示的圆锥结构中，圆锥母线与圆锥底面331之间的夹角为45°，且激光发射组件320的激光发射方向(从下至上)与圆锥结构的中心轴(图3A中圆锥结构内部的虚线)平行，弧形反射面(圆锥面332)与激光发射方向之间的夹角为45°。激光经过弧形反射面反射后，分为了第一激光341(激光出射方向为从右至左)和第二激光342(激光出射方向为从左至右)，其中，第一激光341的激光出射方向与弧形反射面之间的夹角为45°，第二激光342的激光出射方向与弧形反射面之间的夹角也为45°。类似的，激光发射组件320发射的激光在弧形反射面反射后，激光出射方向均与激光入射方向垂直，且与弧形反射面呈45°，使得反射后的激光处于同一平面(与圆锥底面331平行)。
为了使反射后的激光能够透过腔体310投射出去，腔体310的腔体侧面313的预定区域采用透光材料制成，该预定区域指广角反射面组件330的反射面在腔体侧面313的投影区域。
如图3A所示，圆锥结构的高在腔体侧面313的投影区域即采用透光材料制成。同时，为了避免其他激光的干扰，腔体顶面311采用不透光材料制成。
在其他可能的实施方式中，广角反射面组件330的反射面不仅可以为弧形反射面还可以为至少两个平面反射面，如图3B所示，广角反射面组件330为正四棱锥结构，该正四棱锥结构包括正方形锥底面334和四个锥面335，且四个锥面335均为平面反射面。
广角反射面组件330的正方形锥底面334与腔体顶面311固定；激光发射组件320的固定端与腔体底面312固定，且正四棱锥结构的顶点336正对激光发射组件320的发射端321。
激光发射组件320发射的激光在四个锥面335处发生反射后，向四个锥面335各自对应的激光出射方向进行投射。为了使经过反射的激光的处于同一平面上，如图3B所示，正四棱锥结构中，各个锥面335与正方形锥底面334的夹角均为45°，且激光发射组件320发射的激光的激光发射方向与正四棱锥结构的中心轴(即正方形锥底面334中心与顶点336的连接线，图中虚线表示)平行，各个平面反射面(锥面335)与激光发射方向之间的夹角为45°。激光发射组件320发射的激光经过四个平面反射面反射后，激光出射方向均与激光入射方向垂直，且与平面反射面呈45°，使得激光沿同一平面上四个方向射出。
显而易见的，当采用正四棱锥结构作为激光发射组件时，反射后的激光沿同一平面上的四个方向射出，易于思及的，当采用正n棱锥结构作为激光发射组件时，反射后的激光沿同一平面上的n个方向射出。
采用图3A示出的广角反射面组件对激光进行反射时，反射后的激光呈360°射出。在实际实施过程中，该广角反射面组件还可以采用二分之一或四分之一圆锥结构，采用二分之一圆锥结构时，反射后的激光呈180°射出；采用四分之一圆锥结构时，反射后的激光即呈90°射出。如图3C所示，该广角反射面组件330可以为二分之一圆锥结构，经过该二分之一圆锥结构的弧形发射面(二分之一圆锥面332)反射的激光仅从左侧180°范围内射出。
类似的，采用正n棱锥结构作为广角反射面组件时，反射后的激光沿n个方向射出。在实际实施过程中，该广角反射面组件可以仅使用正n棱锥结构中的至少两个平面反射面进行激光的反射，从而实现向多个指定方向发射激光。如图3D所示，该广角反射面组件330可以仅使用正四棱锥结构中相邻的两个平面反射面(锥面335)反射激光，即该广角反射面组件330仅向指定的两个方向投射激光。
可选的，制造人员可以使用不透光材料对广角反射面组件的部分反射面进行遮盖，使得广角反射面组件仅通过未遮盖的反射面进行激光反射，从而实现激光的定向投射。
本实施例中，当广角反射面组件能够同时向多个方向反射激光时，通过遮 盖部分反射面的方式控制广角反射面组件向指定的多个方向反射激光，从而实现了激光的精准定向投射。
如图4A所示，其示出了本发明另一实施例提供的激光接收装置的结构示意图。该激光接收装置包括腔体410、设置在腔体410内部的广角反射面组件420和激光接收组件430。
腔体410包括腔体顶面411、与腔体顶面411平行的腔体底面412以及位于腔体顶面411和腔体底面412之间的腔体侧面413。
如图4A所示，该腔体410可以为圆柱体结构，圆柱体结构的圆柱顶面即为腔体顶面411，圆柱体结构的圆柱底面即为腔体410的腔体底面412，圆柱体结构的圆柱面即为腔体410的腔体侧面413。
若广角反射面组件420的反射面为弧形反射面，如图4A所示，广角反射面组件420可以为圆锥结构，该圆锥结构包括圆锥底面421和圆锥面422。广角反射面组件420的圆锥底面421与腔体顶面411固定，激光接收组件430的固定端与腔体底面412固定，且圆锥结构的顶点423正对激光接收组件430的接收端431。
图4A中，圆锥面422即为广角反射面组件420的弧形反射面，且圆锥母线与圆锥底面421之间的夹角为45°。当水平面上不同方向的激光入射时，弧形反射面(圆锥面422)与激光入射方向之间的夹角为45°，且经过弧形反射面反射的激光的与弧形反射面之间的夹角也为45°；
图4中包含沿着同一平面(水平面)相反方向入射的第一激光441(激光入射方向为从左至右)和第二激光442(激光入射方向为从右至左)，第一激光441和第二激光442在圆锥面422处发生反射，第一激光441的投射方向由从左至右改变为从上至下，第二激光442的投射方向由从右至左改变为从上至下。相似的，该平面上其它方向的激光投射在圆锥面422后，激光的投射方向均改变为从上至下，即同一平面上各个激光入射方向的激光均沿同一激光出射方向投射到激光接收组件430上。
广角反射面组件420的反射面不仅可以为弧形反射面还可以为至少两个平面反射面，如图4B所示，广角反射面组件420为正四棱锥结构，该正四棱锥结构包括正方形锥底面424和四个锥面425，且四个锥面425均为平面反射面。
广角反射面组件420的正方形锥底面424与腔体顶面411固定；激光接收组件430的固定端与腔体底面412固定，且正四棱锥结构的顶点426正对激光 接收组件430的接收侧431。
广角反射面组件420接收到来自同一平面上四个方向的激光后，即通过四个锥面425对激光进行反射。
投向四个锥面425的激光经过反射后，沿同一激光出射方向投射到激光接收组件430上。如图4B所示，正四棱锥结构中，各个锥面425与正方形锥底面424的夹角均为45°。水平面上的第一激光441(从左至右)与(左)锥面425之间的夹角为45°，经过(左)锥面425反射后，投射方向变为了从上至下；同一水平面上的第二激光442(从右至左)与(右)锥面425之间的夹角也为45°，经过(右)锥面425反射后，投射方向也变为了从上至下。类似的，同一平面上其他方向的激光经过相应锥面425反射后，激光出射方向均与正四棱锥结构的中心轴(正方形锥底面424中心与顶点426的连接线，图中虚线表示)平行。显而易见的，经过四个锥面425对四个方向的激光进行反射，同一平面不同方向的激光的投射方向向下偏转90°，沿着正四棱锥结构中心轴的方向投射在激光接收组件430的接收测431，从而达到同时接收多方向激光的效果。
与激光发射装置相似的，为了使外界的激光能够透过腔体410，腔体410的腔体侧面413的预定区域采用透光材料制成，该预定区域指广角反射面组件420的反射面在腔体侧面413的投影区域。同时，为了避免其他激光的干扰，腔体顶面411采用不透光材料制成。
采用图4A示出的广角反射面组件，激光接收装置能够360°接收同一平面上各个方向射入的激光。在实际实施过程中，该广角反射面组件还可以采用二分之一或四分之一圆锥结构，采用二分之一圆锥结构时，激光接收装置能够接收二分之一圆锥结构对应180°方向射入的激光；采用四分之一圆锥结构时，激光接收装置能够接收四分之一圆锥结构对应90°方向射入的激光。
类似的，采用正n棱锥结构作为广角反射面组件时，激光接收装置能够接收n个方向射入的激光。在实际实施过程中该广角反射面组件可以仅使用正n棱锥结构中的至少两个平面对激光进行反射，从而实现接收指定方向的激光，本发明并不对此进行限定。
可选的，制造人员可以使用不透光材料对广角反射面组件的部分反射面进行遮盖，使得激光仅通过未遮盖的反射面进行反射，并投射到激光接收组件， 从而实现激光的定向接收。
本实施例中，当广角反射面组件能够同时向多个方向反射激光时，通过遮盖部分反射面的方式控制广角反射面组件中的指定反射面进行激光发射，从而实现了激光的精准定向接收。
在一个可能的实现场景中，上述各个实施例提供的激光发射装置和激光接收装置可以应用到对战设备中，即对战设备上同时设置有上述实施例提供的激光发射装置和激光接收装置。利用该激光发射装置和激光接收装置，对战设备之间即可通过激光发动模拟攻击(比如通过激光模拟发射炮弹并对其他对战设备造成伤害)，从而模拟出对战设备之间真实对战的效果。其中，该对战设备可以为智能对战玩具车或智能对战玩具飞机等等。
如图5所示，其示出了本发明一个实施例提供的激光发射装置与激光接收装置传输激光过程的示意图。
激光发射装置510设置在第一对战设备上，激光接收装置520设置在第二对战设备上，且激光发射装置510和激光接收装置520位于同一水平高度。第一对战设备通过激光发射组件511向广角反射面组件513发射激光512(竖直向上)，该激光512在反射面513发生反射后，沿着水平方向射出。激光512投射在激光接收装置520中广角反射面组件521的反射面521，在该反射面521发生反射后，竖直向下投射在激光接收组件522，第二对战设备即接收第一对战设备发送的激光512。
作为一种可能的实现方式，激光发射装置510和激光接收装置520可以同时设置在对战设备本体顶部，也可以同时设置在对战设备本体底部，本发明并不对其设置为位置进行限定。安装有上述激光发射装置和激光接收装置的对战设备可以通过激光发射装置向各个方向的其他对战设备发送激光，并可以通过激光接收装置接收各个方向的其他对战设备发送的激光。
当对战设备需要通过激光传输数据时，对战设备中的激光调制电路还需要与激光发射装置中的激光发射组件电性相连。对战设备预先通过激光调制电路对激光进行调制，再通过上述激光发射装置对经过调制的激光进行发射；相应的，对战设备中的激光解调电路还需要与激光接收装置中的激光接收组件电性相连，当通过激光接收组件接收到其它对战设备发射的激光时，通过激光解调电路将激光携带的数据解调出来，从而实现对战设备之间数据的传输。其中， 激光中携带的数据包括攻击类型、伤害数值和发动攻击方标识等等。
显而易见的，对战设备上仅需要设置一个激光接收装置即可接收到各个方向上对战设备发送的激光，仅需要设置一个激光发射装置即可向各个方向的对战设备发送激光，相较于在对战设备本体周测设置多个激光接收管和激光发射管，采用本发明实施例提供的激光发射装置和激光接收装置能够显著降低对战设备的功耗。
