具体实施方式
下面将结合本公开实施例中的附图，对本公开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公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
图1为本公开的一个实施例中的AR眼镜的结构示意图。请参见图1，在一个实施例中，AR眼镜100可以包括主镜片20、虚拟成像模组30以及变焦矫正模组40。
主镜片20可以是树脂或者玻璃等透明材料的片状体。
虚拟成像模组30可以包括例如光投影模块或微显示器等成像元件，以支持投影式或微处理器式的虚拟成像。并且，虚拟成像模组30用于在主镜片20成像。
变焦矫正模组40叠置于主镜片20，例如，变焦矫正模组40可以嵌入在主镜片20中、或者与主镜片20贴合，并且，变焦矫正模组40位于虚拟成像模组30的成像区域，其中，变焦矫正模组40可以包括液体变焦透镜41和透光电极对(即，第一透光电极42a和第二透光电极42b)设置在液体变焦透镜41的相反表面，用于产生使液体变焦透镜41形变的可变电压V_adj。
液体变焦透镜41可以包括液态材料，例如，该液态材料可以选用油液混合物、其介于液态和固态之间。在液体变焦透镜41的两反表面施加不同的电压，液态材料会产生导致折射率变化的形变，随之改变焦距。透光电极对中 包括的第一透光电极42a和第二透光电极42b可以采用透明导电材料，例如N型氧化物半导体-氧化铟锡(Indium tin oxide，ITO)。
图2为图1所示AR眼镜的变焦矫正原理的示意图。请参见图2，变焦矫正模组40响应于可变电压V_adj的电压变化而形变，可以校准在人眼200的视网膜210的成像焦距调节。
可见，在本实施例中，变焦矫正模组40叠置于主镜片20，以使虚拟成像模组30的虚拟成像可以与主镜片20透视的真实成像在变焦矫正模组40处叠加，由于变焦矫正模组40能够利用响应于可变电压V_adj的形变实现焦距调节，因而利用叠置于主镜片20的变焦矫正模组40能够为AR眼镜100赋予视力矫正功能，以避免由于在使用AR眼镜100的同时使用视力矫正装置所导致的使用成本增加、并提高增强现实眼镜的普适性及改善用户体验。
图3为图1所示AR眼镜的主镜片中形成的光路传导的结构原理示意图。如图3所示，虚拟成像模组30在主镜片20的成像区域，偏离于虚拟成像模组30在主镜片20的光投射位置，对于这样的情况，虚拟成像模组30的虚拟成像需要从投射位置传导至变焦矫正模组40所在的成像区域。
为此，本实施例提供了一种基于光波导技术的实现方式，即，AR眼镜100可以进一步包括光波导模组50。该光波导模组50可以嵌入在主镜片20中，并且，该光波导模组50从虚拟成像模组30在主镜片20的光投射位置延展至变焦矫正模组40所在的成像区域。光波导模组50可以看作是在虚拟成像模组30的上述光投射位置与成像区域之间的光波导路径。
例如，在图3中，作为一种可选的实现方式，光波导模组50可以具体包括反射镜片51、衍射光栅膜52、以及半导体耦合镜片53。
反射镜片51具有从虚拟成像模组30在主镜片20的光投射位置接收入射光的入光侧、以及在沿主镜片20的镜面方向上形成反射光的出光侧。例如，反射镜51可以设置虚拟成像模组30在主镜片20的光投射位置，并且反射镜片51可以具有将虚拟成像模组30的投射光调节为沿主镜片20的镜面方向的反射角度。
衍射光栅膜52可以设置在反射镜片51的出光侧与变焦矫正模组40所在的成像区域之间。该衍射光栅膜52可以产生将从入光侧的光分层以衍射方式 传递至出光侧的光波导效应，其可以选用任意一种能够产生此类光波导效应的介质材料。
半导体耦合镜片53设置在衍射光栅膜的出光侧，并且半导体耦合镜片53的光波导耦合成像面位于变焦矫正模组40所在的成像区域内。半导体耦合镜片53可以将以衍射方式分层传递至衍射光栅膜52的出光侧的光耦合得到虚拟成像模组30的投射光中包含的图像内容、并在变焦矫正模组40所在的成像区域内展现。
由此，半导体耦合镜片53在成像区域内展现的图像内容即可作为虚拟成像、并与同样在成像区域内透视的真实成像叠加形成AR图像。叠加的AR图像能够以变焦矫正模组40响应于可变电压V_adj而形变确定的焦距投射到人眼200的视网膜210，以在视网膜210形成清晰的AR图像。
请回看图1，对于可变电压V_adj的调控，本实施例提供了一种便于用户操作的变焦控制部分，即，AR眼镜100可以进一步包括变焦电控模组60和输入模组70。
变焦电控模组60可以驱动透光电极对(第一透光电极42a和第二透光电极42b)产生可变电压V_adj。
输入模组70可以用于接收用户输入、并响应于用户输入，产生调节信号，其中，调节信号用于控制可变电压V_adj。
图4为图1所示AR眼镜的变焦控制部分的结构原理示意图。如图4所示，在上述变焦控制部分的结构中，变焦电控模组60可以包括处理器61和驱动芯片62。处理器61和驱动芯片62之间可以通过例如互连集成电路(Inter-Integrated Circuit，I2C)协议或串行外设接口(Serial Peripheral Interface，SPI)协议等基于串行协议的总线连接。
处理器61可以识别(或者解析)输入模组70产生的调节信号。驱动芯片62则可以依据处理器61识别(或者解析)的调节信号控制透光电极对(即第一透光电极42a和第二透光电极42b)产生的可变电压V_adj。
请再回看图1，AR眼镜100还可以包括镜架10，该镜架10包括镜框11、镜梁12以及镜腿13。
镜框11成对设置，每个镜框11内可以装设有一个主镜片20。镜梁12 桥接在一对镜框11之间。即，本实施例中以双镜片的结构为例。但可以理解是，这样的双镜片结构不应当构成对一体镜片的排斥性限定。
每个镜框11还可以装设有一个虚拟成像模组30。即，并同时基于一对虚拟成像模组30实现可支持二维(2-dimensional，2D)和三维(3-dimensional，3D)的双成像模式。可以理解的是，双成像模式不应当构成对单成像模式的排斥性限定。
在图1中，每个镜框11装设的虚拟成像模组30可以悬置在主镜片20的前侧(AR眼镜100在佩戴时面相成像场景的一侧)，每个镜框11装设的虚拟成像模组30被设置在主镜片20的上部。这同样不应当理解为排斥虚拟成像模组30设置在主镜片20的后侧(AR眼镜100在佩戴时面相人眼的一侧)、以及悬置在主镜片20的下部的设置可能。
镜梁12可以装设变焦电控模组60。变焦电控模组60在镜梁12处可以采用隐藏式安装，例如，镜梁12可以具有容纳变焦电控模组60的内腔。
镜腿13成对地连接在一对镜框11彼此相背的外侧，即，镜腿13成对设置，每个镜腿13连接在镜框11的外侧，并且可以只在其中一个镜腿13装设输入模组70。
为了便于检测用户操作，输入模组70可以暴露在该镜腿13的外侧。并且，考虑到用户操作的执行便利性。输入模组70可以检测用户在镜腿13的长度方向上的滑动触摸，并以检测到的滑动触摸为用户输入，产生调节信号，即，输入模组70接收用户在该镜腿的长度方向上的滑动触摸，并响应滑动触摸，产生调节信号。其中，对于以检测到的滑动触摸为用户输入产生调节信号的情况，可变电压V_adj在调节信号控制下的电压值的变化量，可以与滑动触摸的滑动距离和方向关联。
例如，输入模组70可以包括的触控条模块，用户的操作手沿镜腿13的长度方向滑动即可改变接触位置，相应地，在调节信号控制下的可变电压V_adj即可随着用户的操作手沿镜腿13长度方向的接触位置的偏移量变化而相应变化。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或 者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
上面结合附图对本公开的实施例进行了描述，但是本公开并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本公开的启示下，在不脱离本公开宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本公开的保护之内。
