为了能够更清楚地理解本发明的上述目的、特征和优点，下面结合附图和具体实施例/方式对本发明进行详细描述。需要说明的是，在不冲突的情况下，本申请的实施例/方式及实施例/方式中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本发明，所描述的实施例/方式仅是本发明一部分实施例，而不是全部的实施例/方式。基于本发明中的实施例/方式，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例/方式，都属于本发明保护的范围。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例/方式的目的，不是旨在于限制本发明。
请参阅图2，为本发明提供的光学镜片测试系统100的系统框图。所述光学镜片包括，所述光学镜片包括分光滤光片、透镜及反射镜。光学镜片测试系统100包括光源装置110、光谱测试装置120、控制装置130、存储装置140、输入装置150及显示装置160。其中，控制装置130控制光源装置110用于发出光源光；光谱测试装置120包括用于对所述光源光进行调整以使其适用于测试的光学器件，及用于对待测光学镜片90(图10)出射光线进行收集与分析数据的收集及分析单元127；待测光学镜片90设置于光谱测试装置120的多个元件之间；输入装置150方便用户输入测试参数及操作光学镜片测试系统100；显示装置160用于显示测试的结果，控制装置130与上述各个装置电连接，以协调各装置配合完成待测光学镜片90的光学特性测试。
进一步地，控制装置130可以是中央处理单元(Central Processing Unit，CPU)，还可以是其他通用处理器、数字信号处理器(Digital Signal Processor，DSP)、专用集成电路(Application Specific Integrated Circuit，ASIC)、现成可编程门阵列(Field-Programmable Gate Array，FPGA)或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件等。通用处理器可以是微处理器或者该处理器也可以是任何常规的处理器等，所述处理器是光学镜片测试系统100的控制中心，利用各种接口和线路连接整个光学镜片测试系统100的其他各个部分。
存储装置140用于存储计算机程序和/或模块，控制装置130通过运行或执行存储在存储装置140内的计算机程序和/或模块，以及调用存储在存储装置140内的数据，实现所述服务器的各种功能。存储装置140可主要包括存储程序区和存储数据区，其中，所述存储程序区可存储操作系统、至少一个功能所需的应用程序等；所述存储数据区可存储根据光学镜片测试系统100的使用所创建的数据等。此外，存储装置140可以包括高速随机存取存储装置，还可以包括非易失性存储装置，例如硬盘、内存、插接式硬盘，智能存储卡(Smart Media Card,SMC)，安全数字(Secure Digital,SD)卡，闪存卡(Flash Card)、至少一个磁盘存储装置件、闪存器件、或其他易失性固态存储装置件。
输入装置150可以包括但不限于以下类型的输入装置或其组合：白板、投影按键装置、按键装置、鼠标装置、触控装置、电输入装置、电磁感应装置、压力装置、红外装置或激光装置。
显示装置160包括LCD(液晶显示)、PDA(等离子)或OLED(有机发光二极管)等显示面板中的一种。在一种实施方式中，显示装置160为触摸显示屏，从而输入装置150不需要设置显露于光学镜片测试系统100表面的多个物理按键，进而节省空间、提高了光学镜片测试系统100的便携性能，同时触摸显示屏坚固耐用，有利于延长输入装置130的使用寿命。在又一种实施方式中，显示装置160通过旋转部连接于光学镜片测试系统100表面，且显示装置160能够绕所述旋转部360°自由旋转，以根据不同的视角进行转动，方便用户从不同角度进行观察，有利于降低检测人员的疲劳度。
请参阅图3，为图2所示的光源装置110的第一实施方式的结构示意图。由于R、G、B光的光谱分界一般在500nm和600nm附近，因此，使用的光学镜片中分光滤光片的光谱分界也处于上述波长范围内。对于光学镜片测试系统100而言，测试分光滤光片的光学特性时，需要在500nm和600nm附近有足够亮度的平行宽谱光束出射，才能满足测试需要。本发明提供的光学镜片测试系统100中的光源装置110采用激光荧光光源，以提供亮度高、光学扩展量小的光源光。
进一步地，光源装置110包括第一发光体111、第二发光体112及波长转换元件113。波长转换元件113位于第一发光体111出射激发光所在的光路上，以对所述激发光进行波长转换后产生受激光。第二发光体112出射的补充光与所述受激光合光后得到光源光，所述光源光从光源装置110出射。
其中，第一发光体111与第二发光体112均包括至少一激光器，第一发光体111中的至少一激光器用于发出激光作为所述激发光，第二发光体112中的至少一激光器用于发出激光作为所述补充光。
目前，一般的光学镜片测试系统中的光源装置采用卤钨灯或LED。本发明实施方式提供的光源装置110中采用激光荧光光源相对于卤钨 灯或LED具有明显的优势。具体地，卤钨灯使用寿命相对于激光器短，需要经常更换，使用不方便；所述光源光中的受激光由激光激发波长转换材料形成，所述受激光的光学扩展量小，所述光源光中的未被转换的激发光及补充光均为光学扩展量小的激光，从而所述光源光的扩展量不大，相对来说，LED发光线的光学扩展量大，准直难度高，测试结果精确度不高。光源装置110出射的光学扩展量小的光源光，有利于避免待测光学镜片90由于入射光线角度不同而产生的反射/透射谱线漂移问题，有利于保证并提高测试的精度。
本实施方式中，第一发光体111与第二发光体均采用蓝色激光器，以发出蓝色激发光。其中，第一发光体111出射蓝色激发光波长为455nm，第二发光体112出射蓝色补充光波长为445nm。可以理解的是，第一发光体111与第二发光体112不限于采用蓝色激光器，也可以采用紫色激光器、红色激光器或绿色激光器等。可以理解，第一发光体111可以包括一个、两个蓝色激光器或蓝色激光器阵列，具体其激光器的数量可以依据实际需要选择。
波长转换元件113包括本体114及驱动单元115，驱动单元115与本体114连接以带动本体114做周期性运动。在本实施方式中，本体114呈圆盘状，驱动单元115设置于本体114的几何中心位置，驱动单元115包括电机，驱动单元115带动本体114做周期性旋转。在一种实施方式中，驱动单元115设置于本体114的一端，以驱动本体114做周期性的往复运动。
本体114上设置有用于将所述激发光转换为受激光的波长转换材料。所述波长转换材料将蓝色激发光转换为波长范围为500nm和600nm附近的光线，请参阅图4，图4为图3所示的光源装置110出射光源光的光谱图。所述光源光光谱曲线在450nm附近具有两个峰值，分别对应445nm的补充光及455nm的激发光，所述光源光功率主要分布于500nm-600nm之间，中心波长在530nm附近。相应地，所述波长转换材料主要为对应530nm的绿色荧光粉。
请参阅图5，为图3所示的光源装置110的第二实施方式的波长 转换元件113的结构示意图。本实施方式提供的波长转换元件213包括第一转换区213a与第二转换区213b，激发光选择性照射第一转换区213a及/或所述第二转换区213b，第一转换区213a及第二转换区213b在所述激发光的激发下出射受激光的中心波长不重叠。
具体地，请参阅图6-图7，图6为图5所示的第一转换区213a位于所述激发光所在光路时所述光源光的光谱图。图7为图5所示的第二转换区213b位于激发光所在光路时所述光源光的光谱图。波长转换元件213的驱动单元在控制装置130的控制下选择性移动第一转换区213a或第二转换区213b位于所述激发光所在的光路上。第一转换区213a在所述激发光的激发下产生中心波长在500nm左右的蓝绿色光，相应地，第一转换区213a设置有对应500nm的蓝绿色荧光粉；第二转换区213b在所述激发光的激发下产生中心波长在600nm左右的橙色光，相应地，第二转换区213b设置有对应600nm的橙色荧光粉。在一种实施方式中，受激光优选覆盖第一波长范围，相应地，波长转换元件213上设置用于出射第一波长范围内受激光的波长转换材料。
在一种实施方式中，光源装置110包括多个波长转换元件113，第一发光体111选择性照射多个波长转换元件113，以出射对应波长范围的受激光，任意两个波长转换元件113出射受激光的中心波长不重叠。光源装置110可以根据待测光学镜片的光谱分界来选择性照射多个波长转换元件113中的一个或几个。可以理解的是，光源装置110可以分时选择性照射多个波长转换元件113中的一个或几个，即在测试的过程中，更换位于激发光所在光路上的波长转换元件113，或多个波长转换元件113的位置是固定的，控制装置130配合调整第一发光体111出射激发光的传播方向。
请参阅图8，为图3所示的光源装置110的第三实施方式的出射光源光的光谱图。所述光源光在红色激光波段具有较高功率密度，相应地，光源装置110的第二发光体112包括用于发出红色激光的红色激光器，光源装置110出射的补充光包括所述红色激光。所述光源光 用于检测待测光学镜片对于红色激光的反射/透射特性，有利于扩展光学镜片测试系统100的测试谱线范围。可以理解的是，第二发光体112中的红色激光器的数量可以根据实际需要进行选择。
请参阅图9，为图3所示的光源装置110的第四实施方式的出射光源光的光谱图。光源装置110出射光源光在440-670nm左右范围内均具有较高的能量，光功率密度曲线上450nm处的峰值对应蓝色激光的光功率。
相应地，光源装置110中的第一发光体111包括用于发出紫外激发光(400nm以下)的紫外激光器，波长转换元件113设置有蓝色荧光粉，所述紫外激发光激发所述蓝色荧光粉产生蓝色受激光，从而所述光源光在450nm-500nm之间具有较高的能量分布。在本实施方式中，光源装置110包括第二发光体112，第二发光体112包括蓝色激光器(450nm左右)，所述蓝色激光器发出的蓝色激光与波长转换元件113出射的受激光合光后得到所述光源光。
通过在光源装置110中补充紫外激发光激发蓝色荧光粉，有利于提高所述光源光在440nm-500nm左右波长范围内的光能量，从而所述光源光的光谱在440nm～670nm都有较高的光能量来进行光学镜片检测，光学镜片测试系统100能够对分光滤光片、透镜及反射镜进行在可见光范围内的光学特性测试，有利于光源装置110在光学镜片检测领域中的推广及应用。
在一种实施方式中，光源装置110不包括第二发光体112，第一发光体111出射的激发光激发波长转换元件113上的波长转换材料产生受激光，所述受激光及未被转换的激发光从光源装置110出射。
上述例举的光源装置110的实施方式中波长转换元件113及波长转换元件213均为透射式波长转换元件，可以理解的是，本发明实施方式中可以采用第一发光体111激发反射式波长转换元件113，相应地，波长转换元件113的出光光路上设置其他本领域公知光学器件，亦属于本发明的专利保护范围。
本发明实施方式提供的光源装置110采用激光荧光光源，光源装 置110使用寿命长，出射光源光亮度高，光学扩展量小。
请参阅图10，为图3所示的光源装置110及光谱测试装置120的结构示意图。光谱测试装置120包括第一光阑125、第二光阑121、准直单元123、以及收集及分析单元127。光源装置110发出的激发光依次经过第二光阑121、准直单元123、第一光阑125照射至待测光学镜片90上，待测光学镜片90对所述光源光进行反射或散射，自待测光学镜片90出射的光线经收集及分析单元127的处理后得到不同波长光线的强度。
具体地，准直单元123用于将所述光源光调整为大致平行光。本发明所述的“大致平行光”是指光线的发散角较小，在误差范围内认为是平行光。优选地，准直单元123出射的大致平行光的发散角在±10度的范围内。在本发明的一个优选的实施方式中，准直单元123出射大致平行光的发散角在±5度的范围内。在本发明的一个优选的实施方式中，准直单元123出射大致平行光的发散角在±2度的范围内。在该范围内，准直单元123出射的大致平行光在人眼可察觉范围内表现为平行光。可以理解，在最理想的情况下，准直单元123出射光线的发散角为0度，使得准直单元123出射的光线为绝对平行光，但实际的误差精度难以做到这一点，只能令发散角趋近于0度。
准直单元123为任意具有准直光束功能的光学元件或光学系统。在本实施方式中，准直单元123包括准直透镜。在准直单元123与光源装置110之间还设置有第二光阑121，第二光阑121用于将光源装置110出射的光源光的光斑调整至合适的大小，有利于提高所述光源光经过所述准直透镜准直后的平行度。本实施方式中，第二光阑121为小孔光阑。
在一种实施方式中，光源装置110出光面较小，由于所述光源光的光学扩展量较小，从而出射光源光的光斑较小，进而可以省略第二光阑121，光源装置110出射的光源光的较小光斑经过准直单元123后即得到所述大致平行光。
在一种实施方式中，准直单元123包括非球面透镜或自由曲面透 镜。非球面透镜或自由曲面透镜能够准直出光面较大的光源装置110发出的光源光。在本实施方式中，可以省略第二光阑121，光源装置110出射的光源光直接经非球面透镜或自由曲面透镜出射后为所述大致平行光。
在一种实施方式中，准直单元123包括由多个透镜组合而成的准直透镜组。可以理解的是，准直单元123还可以采用集成的准直器。
第一光阑125设置于待测光学镜片90与准直单元123之间，第一光阑125包括通光孔，所述大致平行光穿过所述通光孔照射至待测光学镜片90上。在一种实施方式中，所述通光孔的尺寸小于待测光学镜片90，以调整所述大致平行光的光斑大小，使得所述大致平行光照射在待测光学镜片90局部，便利测量待测光学镜片90局部的光学特性。第一光阑125可选取小孔或其它形状的光阑，优选地，第一光阑125为狭缝光阑。所述狭缝光阑的出光孔呈长条形，有利于所述出光孔沿一个方向相对待测光学镜片90移动，并测得待测光学镜片90上沿所述一个方向排布的每个区域的光学特性。
由于第一光阑125出射的光线照射至待测光学镜片90的局部区域，以关注待测光学镜片90某个小区域内的透/反射谱线，测量时第一光阑125挡住了所述大致平行光中的大部分光束，因此能够用于测量的光束很少，光源装置110出射光线亮度高，有利于保证并提高测量的精度。
待测光学镜片90设置于第一光阑125与收集及分析单元127之间。待测光学镜片90与第一光阑125间隔预设距离。在一种实施方式中，待测光学镜片90紧贴第一光阑125，有利于提高测量的精度及光能利用率。
在一种实施方式中，光学镜片测试系统100能够调整待测光学镜片90相对于光源装置110的摆放角度，以调节待测光学镜片90的光线入射角。在一种实施方式中，待测光学镜片90的摆放角度可以在360度的范围内准确的调节，以便测量待测光学镜片90对不同角度入射光的响应。
光学镜片测试系统100能够调整待测光学镜片90相对于光源装置110的位置，以便利第一光阑125出射的光线能够照射至待测光学镜片90上的全部区域。第一光阑125在一个时刻出射的光线能够照射待测光学镜片90上的局部区域，调整待测光学镜片90相对于光源装置110的位置，使得在特定时间段内，第一光阑125出射的光线能够照射至待测光学镜片90上的全部区域，以完成整片镜片的测试。
可以理解的是，第一光阑125可以与待测光学镜片90一同调整相对于光源装置110的摆放角度及/或位置。
在一种实施方式中，光学镜片测试系统100还包括至少一设置于光源装置110及第一光阑125之间的偏振分光元件124。偏振分光元件124出射的偏振光经过第一光阑125入射至待测光学镜片90上，以便测试偏振片的光学特性。由于光束垂直入射时偏振分光元件124时偏振特性会更好，在本实施方式中，偏振分光元件124设置于准直单元123及第一光阑125之间，使得所述大致平行光垂直入射至偏振分光元件124后出射。偏振分光元件124可以为偏振分光片或偏振棱镜。
收集及分析单元127用于收集并分析待测光学镜片90出射的光线。收集及分析单元127包括积分球127a及与积分球127a连接的光谱仪127b。光谱仪127b用于测量不同波长位置的光线强度。
其中，待测光学镜片90出射的光线进入积分球127a后，经过内壁涂层多次反射，在内壁上形成均匀照度。在一种实施方式中，积分球127a包括左半球和右半球，光度计置于所述右半球的中心面，光度计挡板置于所述光度计前面且与所述光度计间隔开；待测光学镜片90至少向所述左半球的照明区发光，辅助灯部置于所述左半球和所述右半球之间的接触区附近，以向照明区发光，辅助灯挡板置于所述辅助灯部周围，以防止待测光学镜片90发出的光直接照射到所述辅助灯部，并且也防止从所述辅助灯部发出的光直接照射到待测光学镜片90。
在一种实施方式中，收集及分析单元127包括光电探测器。在一种实施方式中，所述光电探测器的窗口由高透明的Al 2O 3陶瓷片制成的，且紧靠近探测元表面。以解决了目前蓝宝石晶体窗口存在的功能 单一成本高的缺点，其光线透过率高，光谱透射范围宽。在一种实施方式中，光电探测器为集成有波导的石墨烯光电探测器，有利于实现低功率、大数据量传输的光互连。
图10所示的光谱测试装置120的设置位置适用于测试透射特性的情况，可以理解的是，在测试反射特性时，收集及分析单元127能够做相应的位置调整，以收集待测光学镜片90反射的光线。
请参阅图11，为图2所示的光学镜片测试系统100的测试流程图。其中，光源装置110发射光谱较宽的大致平行光，所述大致平行光照射在置于待测光学镜片90上，经过待测光学镜片90透/反射后，进入收集及分析单元127，测量得到不同波长光的强度数据，将所述数据与不加待测光学镜片90时光源装置110出射光源光的强度数据相比，就能得出待测光学镜片90的透/反射特性。
本发明实施方式提供的光学镜片测试系统100包括光源装置110，其中，光源装置110采用激光荧光光源，以提供亮度高、光学扩展量小的光源光，有利于提高光学镜片测试系统100的测试精度。
在本发明所提供的几个实施例/方式中，应当理解的是，所述的方法和装置，也可以通过其他的方式来实现，以上所描述的装置实施例仅是示意性的，所述模块的划分，是一种逻辑功能划分，实现时可以有另外的划分方式。
