Description

目镜、眼镜、头盔式显示器和VR系统
本申请要求2018年2月5日提交至中国知识产权局的，申请号为201810119943.4，名称为“目镜及配有目镜的眼镜”的中国发明专利申请的优先权，其全部公开内容结合于此作为参考。
技术领域
本申请涉及一种目镜结构，特别的，涉及一种目镜、一种眼镜、一种头盔式显示器以及一种VR(Virtual Reality，虚拟现实)系统。
背景技术
头盔式显示器是近年来显示领域的热门产品，用于虚拟现实和增强显示的头盔图像显示装置取得了长足的发展。由于头盔显示装置安装在观察者的头部，因此它必须结构紧凑、重量轻，以减轻观察者的头部负担。头盔显示器主要由三个部分构成：显示部件、光学系统和头盔。其中光学系统是实现虚拟现实技术的核心。
光学系统具有将微型图像显示在人眼前形成虚拟放大图像的功能。但光学系统的紧凑与头盔显示器对光学系统成像质量的要求之间存在一定的矛盾。对于头盔显示器而言，要求光学系统可以做到比较大的视场和出瞳直径，因为观察视场的增加，观察范围也会增加，观察者才能更全神贯注的观察优质的动态图像，出瞳直径增加可以保证头盔适应不同瞳距的观察者，而不必调整头盔的瞳距，同时允许观察者在观察过程中眼珠能随意转动而不至于丢失图像。但光学系统的视场、出瞳直径、焦距三者之间有相互制约的关系，同时达到大视场，大出瞳直径和短焦(即系统的紧凑化)并不容易。
现有技术提供了一种由多个透镜共轴组成的透镜组，通过不同焦距的透镜共轴排列将图像放大，进而实现增大视场角的效果。但是透镜组内透镜数量多、同时要求各透镜皆为高分辨率透镜，导致了其透镜组制造难度大，价格高昂。同时，透镜组所能达到的视场角相距人眼的视场角还有很大差距，无法实现很好的沉浸效果。针对现有技术存在的多个透镜共轴排列所造成的透镜数量多、 视场角狭窄的问题，目前还没有解决方案。
公开于本申请背景技术部分的信息仅仅旨在加深对本申请的一般背景技术的理解，而不应当被视为承认或以任何形式暗示该信息构成已为本领域技术人员所公知的现有技术。

实施例1
如图1所示，本发明创造涉及一种目镜，该目镜包括：第一透镜部1和第二透镜部2，所述第一透镜部1与第二透镜部2相连接，所述第一透镜部1的视场角与所述第二透镜部2的视场角形成目镜的整体视场角。
可选地，所述第一透镜部1与第二透镜部2的像侧面所形成的夹角为钝角。
可选地，第一透镜部1与第二透镜部2的像侧面所形成的夹角在110°-130°的范围内。
可选地，整体视场角为70°-110°。
可选地，第一透镜部1的视场角范围为40°-65°，所述第二透镜部2的视场角范围为30°-45°。
可选地，第一透镜部1的视场角大于第二透镜部2的视场角。
可选地，第一透镜部1的视场角为65°，所述第二透镜部2的视场角为45°。
可选地，第一透镜部1的中心厚度为1-20mm，边缘厚度为1-4mm。
可选地，第二透镜部2的厚度为1-4mm。
可选地，第二透镜部2的厚度与所述第一透镜部1的边缘厚度相同。
可选地，第一透镜部1为球面、非球面与菲涅尔透镜中的一种。
可选地，第二透镜部2为单面具有齿环结构的菲涅尔透镜，齿环结构表面朝向屏幕，光滑表面朝向人眼。
可选地，第一透镜部1的焦距为30mm-60mm。
可选地，第二透镜部2的焦面与所述第一透镜部1的焦面共面。
可选地，第一透镜部1与所述第二透镜部2上均覆有增透膜。
可选地，第一透镜部1的材质与所述第二透镜部2的材质均为光学塑料，所述光学塑料为pmma、pc、e48r或k26r中的一种。
可选地，第一透镜部1与所述第二透镜部2之间连接的方式为拼接、接合或一体成型。
在本发明创造实施例中，采用第一透镜部1与第二透镜部2相连接的方式，通过在第一透镜部1上只添加一片具有扩大视场角效果的第二透镜部2，从而实现了增大视场角与减少透镜数量的的有益效果，进而解决了由于多个透镜共轴排列所造成的透镜数量多与视场角狭窄的技术问题。
实施例2
如图1所示，本发明创造涉及一种目镜，该目镜包括第一透镜部1和第二透镜部2，所述第一透镜部1与第二透镜部2相连接，所述第一透镜部1的视场角与所述第二透镜部2的视场角形成目镜的整体视场角。
第一透镜部1与第二透镜部2通过光学光敏胶胶合在一起。
第一透镜部1与第二透镜部2的像侧面所形成的夹角为130°。将第一透镜部1与第二透镜部2连接时，如选择将两透镜部的像侧面夹角设计为锐角，会削弱目镜的整体视场角，也带来很大的制造难度，因此将像侧面的夹角设计为钝角可以最大程度的保证目镜的视场角，也易于制造生产。
所述目镜的整体视场角设置为110°。人眼的单侧视场角为100-110°，透镜的视场角越接近人眼的视场角，越能提高人在使用虚拟现实过程中的沉浸 感。
第一透镜部1视场角设计为65°，第二透镜部2视场角设计为45°。将第一透镜部1与第二透镜部2相接合时会产生接缝，为防止接缝处影响到人眼主视野的观察效果，将第一透镜部1的视场角设计的大于第二透镜部2的视场角，将接缝处调整到边缘视野，保证了主视野的观察效果。
第一透镜部1为菲涅尔透镜，采用菲涅尔透镜可以在保证透镜厚度的同时提供较大的视场角。
第一透镜部1的焦距为30mm，焦距小于30mm的透镜距离人眼过近，使人眼无法清晰的对物体对焦；焦距大于60mm的透镜，使透镜距离人眼过远，影响透镜的整体视场角。因此将透镜的焦距设置在30mm-60mm可以同时具有良好的视场角与观察效果。
第一透镜部1的中心厚度为4mm，边缘厚度为1mm。
第二透镜部2为单面具有齿环结构的菲涅尔透镜，齿环结构表面朝向屏幕，光滑表面朝向人眼。
第二透镜部2的焦面与第一透镜部1的焦面共面。
第二透镜部2的厚度为1mm，与第一透镜部1的边缘厚度一致。
第二透镜部2材质为e48r，具有透光性好、重量轻、易于成型的特点，在保证分辨率的基础上，避免了光学玻璃自身重量较大所造成的不适感。
第一透镜部1与第二透镜部2上覆有增透膜，增大透镜的透光率。
实施例3
如图1所示，本发明创造涉及一种目镜，该目镜包括第一透镜部1和第二透镜部2，所述第一透镜部1与第二透镜部2相连接，所述第一透镜部1的视场角与所述第二透镜部2的视场角形成目镜的整体视场角。
第一透镜部1与第二透镜部2通过一体成型注塑在一起。
第一透镜部1与第二透镜部2的像侧面所形成的夹角为110°。
所述目镜的整体视场角设置为70°。
第一透镜部1视场角设计为40°，第二透镜部2视场角设计为30°。
第一透镜部1为非球面透镜。
第一透镜部1的焦距为60mm。
第一透镜部1的中心厚度为20mm，边缘厚度为4mm。
第二透镜部2的焦面与第一透镜部1的焦面共面。

以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均包含在本申请的保护范围之内。
工业实用性
本申请的目镜采用第一透镜部与第二透镜部相连接的方式，通过在第一透镜部上只添加一片具有扩大视场角效果的第二透镜部，从而实现了增大视场角与减少透镜数量的的有益效果，进而解决了由于多个透镜共轴排列所造成的透镜数量多与视场角狭窄的技术问题。
