【具体实施方式】
以下描述中，为了说明而不是为了限定，提出了诸如特定系统结构、接口、技术之类的具体细节，以便透彻理解本申请。然而，本领域的技术人员应当清楚，在没有这些具体细节的其它实施方式中也可以实现本申请。在其它情况中，省略对众所周知的装置、电路以及方法的详细说明，以免不必要的细节妨碍本申请的描述。
参阅图1、图2以及图3，图1是本发明光学防伪系统一实施方式的结构示意图。图2是本发明光学防伪系统中移动终端的发光器件驱动电路图。图3是本发明光学防伪系统中移动终端的发光器件的一结构示意图。本实施方式中，光学防伪系统包括：移动终端110以及防伪标签120。其中，
移动终端110中包括发光器件111和用于驱动发光器件111的驱动电路113。发光器件111至少能够依次或交替产生两种不同波长的红外光。发光器件300为共阴或共阳双色红外LED灯，包括第一引脚、第二引脚和第三引脚，第一引脚和第二引脚驱动LED灯可发出第一波长的红外光，第二引脚和第三引脚驱动LED灯可发出第二波长的红外光。在本实施方式中，以发光器件111能够依次产生两种不同波长的红外光为例。发光器件111可以是将两个发出不同波长的红外光的LED芯片（第一LED芯片以及第二LED芯片）分别封装成两个不同的LED灯，也可以是将两个发出不同波长的红外光的LED芯片（第一LED芯片D1以及第二LED芯片D2）封装到同一个LED灯中，或者是以其他任何方式封装在一个LED灯中可发出两种不同波长的红外光的LED灯。其中，第一LED芯片D1能够产生波长为800nm的红外光，第二LED芯片D2能够产生波长为1500nm的红外光。驱动电路113包括第一电阻R1、反相器S1以及第二电阻R2，其中，第一电阻R1的一端用于输入驱动电平，第一电阻R1的另一端连接第一LED芯片D1的一端，第一LED芯片D1的另一端接地，反相器S1的一端用于输入驱动电平，反相器S1的另一端连接第二电阻R2的一端，第二电阻R2的另一端连接第二LED芯片D2的一端，第二LED芯片D2的另一端接地。
防伪标签120上设置有至少两个不同图案，每个图案由至少一种油墨材料形成，每个图案对应一种红外光，并且只在对应波段的红外光照射下发出可见光。特别地，至少两个不同图案上下叠置、至少部分叠置或水平错开，发光器件111依次或交替产生至少两种不同波长的红外光以照射在至少两个不同图案上，以使防伪标签产生动态图案效果。本实施例中，防伪标签120上用两种不同油墨材料印刷有两种图案（第一图案121以及第二图案122）。其中，油墨材料为红外上转换标识材料（红外上转标识材料是利用对红外线（800-1500纳米）有不同的吸收特点，通过仪器检测或识别其印记，在普通光照射下无任何反应，而在红外光的照射下可以检测其相应的信号或图文，具体可参考红外-可见光的上转换材料研究进展http://www.docin.com/p-575727238.html）。形成第一图案121的油墨材料在波长为800nm的红外光的照射下产生可见光，从而形成第一图案121；形成第二图案122的油墨材料在波长为1500nm的红外光的照射下产生可见光，从而形成第二图案122。
在工作时，用户第一次按下按键时，处理器（图未示）检测到按键第一次被按下，于是处理器向驱动电路113输出驱动电平，驱动电平为高电平，电流通过第一电阻R1使第一LED芯片D1发光，产生波长为800nm的红外光。同时，反相器S1对驱动电平进行反相，输出低电平，第二电阻R2以及第二LED芯片D2中没有电流通过，第二LED芯片D2不发光。
第一LED芯片D1所产生的800nm的红外光照射到防伪标签120上，防伪标签120形成第一图案121的油墨材料在波长为800nm的红外光的照射下产生可见光，从而形成第一图案121。用户观察到第一图案121。
用户第二次按下按键时，处理器（图未示）检测到按键第二次被按下，于是处理器向驱动电路113输出驱动电平，驱动电平为低电平，第一电阻R1以及第一LED芯片D1中没有电流通过，第一LED芯片D1不发光。同时，反相器S1对驱动电平进行反相，输出高电平，第二电阻R2以及第二LED芯片D2中通过电流，第二LED芯片D2发光，产生波长为1500nm的红外光。
第二LED芯片D2所产生的1500nm的红外光照射到防伪标签120上，防伪标签120形成第二图案122的油墨材料在波长为1500nm的红外光的照射下产生可见光，从而形成第二图案122。用户观察到第二图案122。
在另一种实施方式中，也可以用户按下按钮时，处理器（图未示）检测到按键被按下，于是处理器交替向驱动电路113输出高电平和低电平，使得第一LED芯片D1和第二LED芯片D2交替产生红外光，防伪标签120轮流显示第一图案121和第二图案122，从而显示出动态效果。例如，第一图案121和第二图案122重叠在一起，第一图案121是一个向上举手的卡通人物，而第二图案122是一个向下伸手的卡通人物，两种红外光高速地切换，在人眼视网膜的停留效应下，呈现了卡通人物不停地向上举手和向下伸手的效果。
一并参阅图4，图4是本发明光学防伪系统另一实施方式的结构示意图。本实施方式中，光学防伪系统包括：移动终端410以及防伪标签420。其中，
移动终端410中包括发光器件411和用于驱动发光器件411的驱动电路113，用于获取至少两种不同波长的红外光反射而形成的至少两种图案的摄像头412和用于依次或交替显示摄像头412所获取到的至少两种图案的显示屏414。发光器件411可以是至少能够依次或交替产生两种不同波长的红外光的LED灯，也可以是能依次或交替产生两种不同波长的红外光的闪光灯。发光器件300为共阴或共阳双色红外LED灯，包括第一引脚、第二引脚和第三引脚，第一引脚和第二引脚驱动LED灯可发出第一波长的红外光，第二引脚和第三引脚驱动LED灯可发出第二波长的红外光。在本实施方式中，以发光器件411能够依次产生两种不同波长的红外光为例。发光器件411可以是将两个发出不同波长的红外光的LED芯片（第一LED芯片以及第二LED芯片）分别封装成两个不同的LED灯，也可以是将两个发出不同波长的红外光的LED芯片（第一LED芯片D1以及第二LED芯片D2）封装到同一个LED灯中，或者是以其他任何方式封装在一个LED灯中可发出两种不同波长的红外光的LED灯。其中，第一LED芯片D1能够产生波长为800nm的红外光，第二LED芯片D2能够产生波长为1500nm的红外光。驱动电路113包括第一电阻R1、反相器S1以及第二电阻R2，其中，第一电阻R1的一端用于输入驱动电平，第一电阻R1的另一端连接第一LED芯片D1的一端，第一LED芯片D1的另一端接地，反相器S1的一端用于输入驱动电平，反相器S1的另一端连接第二电阻R2的一端，第二电阻R2的另一端连接第二LED芯片D2的一端，第二LED芯片D2的另一端接地。
防伪标签420上设置有至少两个不同图案，每个图案由至少一种油墨材料形成，每个图案对应一种红外光，并且只在对应波段的红外光照射下才反射该红外光，并通过移动终端410观察到防伪标签420上的图案。特别地，至少两个不同图案上下叠置、至少部分叠置或水平错开，发光器件411依次或交替产生至少两种不同波长的红外光以照射在至少两个不同图案上，以使摄像头412获取至少两种不同波长的红外光反射而形成的至少两种图案，并通过移动终端410的显示屏414依次或交替显示所获取到的至少两种不同图案，以使防伪标签产生动态图案效果。本实施例中，防伪标签420上用两种不同油墨材料印刷有两种图案（第一图案421以及第二图案422）。其中，油墨材料为只在对应波段的红外光照射下才反射该红外光的红外反射材料（具体可参考中国发明专利申请CN101225265A中公开了一种对不同波段红外光的吸收/反射具有明显反差的防伪油墨）。形成第一图案421的油墨材料在波长为800nm的红外光的照射下产生人眼不可见的红外光，从而形成人眼不可见的第一图案421，该红外光漫反射后被红外摄像头412接收形成第一图案413，并通过显示屏414显示第一图案413，使用户可观察到第一图案413；形成第二图案122的油墨材料在波长为1500nm的红外光的照射下产生人眼不可见的红外光，从而形成人眼不可见的第二图案422，该红外光漫反射后被红外摄像头412接收形成第二图案415，并通过显示屏414显示第二图案415，使用户可观察到第二图案415。
在工作时，用户第一次按下按键时，处理器（图未示）检测到按键第一次被按下，于是处理器向驱动电路113输出驱动电平，驱动电平为高电平，电流通过第一电阻R1使第一LED芯片D1发光，产生波长为800nm的红外光。同时，反相器S1对驱动电平进行反相，输出低电平，第二电阻R2以及第二LED芯片D2中没有电流通过，第二LED芯片D2不发光。
第一LED芯片D1所产生的800nm的红外光照射到防伪标签420上，防伪标签420形成第一图案421的油墨材料在波长为800nm的红外光的照射下产生人眼不可见的红外光，从而形成人眼不可见的第一图案421，该红外光漫反射后被红外摄像头412接收形成第一图案413，并通过显示屏414显示第一图案413，用户观察到第一图案413。
用户第二次按下按键时，处理器（图未示）检测到按键第二次被按下，于是处理器向驱动电路113输出驱动电平，驱动电平为低电平，第一电阻R1以及第一LED芯片D1中没有电流通过，第一LED芯片D1不发光。同时，反相器S1对驱动电平进行反相，输出高电平，第二电阻R2以及第二LED芯片D2中通过电流，第二LED芯片D2发光，产生波长为1500nm的红外光。
第二LED芯片D2所产生的1500nm的红外光照射到防伪标签420上，防伪标签420形成第二图案422的油墨材料在波长为1500nm的红外光的照射下产生人眼不可见的红外光，从而形成人眼不可见的第二图案422，该红外光漫反射后被红外摄像头412接收形成第二图案415，并通过显示屏414显示第二图案415，用户观察到第二图案415。
在另一种实施方式中，也可以用户按下按钮时，处理器（图未示）检测到按键被按下，于是处理器交替向驱动电路113输出高电平和低电平，使得第一LED芯片D1和第二LED芯片D2轮流产生红外光，使显示屏交替显示摄像探头412所获取到的第一图案413和第二图案415，从而显示出动态效果。例如，人眼不可见的第一图案421和第二图案422重叠在一起，第一图案421是一个向上举手的卡通人物，而第二图案422是一个向下伸手的卡通人物，两种红外光高速地切换，红外摄像头412交替获取到两种红外光反射而形成的第一图案413和第二图案415，在人眼视网膜的停留效应下，在移动终端410的显示屏414上呈现了卡通人物不停地向上举手和向下伸手的效果。
此外，本发明还分别提供了一种移动终端以及防伪标签，具体请参阅图1、图2、图3、图4及相关描述，此处不重复一一赘述。
基于上述方案，本发明通过移动终端产生至少两种不同波长的红外光，而且，在每种波长的红外光的激发下，防伪标签上都有一种油墨材料被红外光激发产生可见光产生一种肉眼可见的图案或产生一种肉眼不可见的红外光，该红外光漫反射后被红外摄像头接收形成人眼可见的图案。在这种情况下油墨材料的获取制造都比较困难，大大提高了仿制厂家仿制的难度，提高了防伪的可靠性。
在本申请所提供的几个实施方式中，应该理解到，所揭露的系统，装置和方法，可以通过其它的方式实现。例如，以上所描述的装置实施方式仅仅是示意性的，例如，所述模块或单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性，机械或其它的形式。
