Abstract

一种反射式手机电影镜，包括半反射镜（5）、凹球面反射镜（4）、手机（1）屏幕。手机（1）屏幕作为显示屏，用来显示影像。视线通过半反射镜（5）达到凹球面反射镜（4），再由凹球面反射镜（4）反射回半反射镜（5），再由半反射镜（5）的反射面反射到手机（1）屏幕上。这种手机电影镜可通过手机（1）看网络电影或玩虚拟现实游戏，能够获得像电影院大银幕一样的观看效果。

Description

反射式手机电影镜
技术领域 本发明涉及一种光学放大装置，尤其是一种对手机屏幕放大的装置。
背景技术 随着科技的发展，手机显示屏的像素越做越高，小小的5寸左右的屏幕做到了1920*1080的像素，还有2560*1440的，甚至还会发展到3840*2160的4K超高清像素，小小屏幕所具有的像素与最先进的大电视机做到了一样，像素密度已经超过人眼识别的范围。在手机上看网络视频还特别方便、特别节省，还具有私密性，不影响他人，有很多大电视机所不及的优点。但是，人们看电影不仅需要清晰度，还需要大幅面IMAX带来的震撼，还需要去识别肉眼看不清的细节，所以手机看电影还存在一个幅面太小的问题。
发明内容 为了克服这个缺憾，本发明提供了一种反射式手机电影镜，用凹球面反射镜对手机屏幕进行放大。
本发明解决其技术问题所采用的技术方案是：本电影镜利用手机屏幕显示影像，眼睛看出视线通过眼睛前方与视线倾斜的半反射镜达到与眼睛相对的凹球面或凹非球面反射镜上，再由凹球面反射镜反射回半反射镜，再由半反射镜的反射面反射到半反射镜上方放置的手机屏幕上。
本发明的有益效果是：该凹球面反射镜方式构成的手机电影镜体积小、重量轻，没有凸透镜的色差问题，没有注塑凸透镜难以克服的缩水问题，没有大凸透镜厚度造成的重量问题。该电影镜能利用先进 的手机设备，不仅能带给人们IMAX巨幕影院或虚拟现实游戏的娱乐享受，还可为人们轻松构建一个可用于某些工作学习需要的影像显示或监视的高端设备。

图中：1.手机，2.目镜放大镜，3.放大镜，4.单凹球面反射镜，5.半反射镜(半透镜)，6.双凹球面反射镜，7.3D隔离挡光板。
具体实施方式
1.放大普通2D画面光路 两眼视线分别通过同一半反射镜(5)投向同一单凹球面反射镜(4)上(图2、图3)，视线经凹球面反射镜反射回来，经半反射镜的反射面再反射到手机(1)屏幕上。凹球面反射镜放大原理等效放大镜(3)(图1)，两眼光路等效图1，图中目镜放大镜(2)略往中间偏移视线，目的是避免斗鸡眼视线不舒服的感觉。目镜放大镜还有加大视场的作用，可增加放大的幅面(图2)。
2. 3D光路 两眼视线分别通过半反射镜投向双凹球面反射镜(6)各自对应的凹球面反射镜上(等效图4)，视线经凹球面反射镜反射回来，经半反射镜的反射面再反射到手机屏幕显示的具有视差的 各自左右两个画面上。两眼光路之间有3D隔离挡光板(7)隔离，两眼光路等效图4。图中两目镜放大镜略往两端偏移，目的是避免左右视差画面中心间距大于两眼瞳距的情况。双凹球面反射镜(6)由两凹球面反射镜左右拼在一起(图5)，合起来的面积与2D的单个凹球面反射镜(4)面积一样大，使之在装置中能互换，配合可拆卸的3D隔离挡光板，达到2D、3D通用。
3.凹球面反射镜 凹球面反射镜有单双之分，单双凹球面反射镜的球面曲率一致，单双凹球面反射镜的面积一样大，与电影镜装置的固定接口一致，作为2D、3D用途互换。凹球面反射镜包括矫正相差的凹非球面反射镜。
4.光路设计 光路设计以正方形为框架(图2)，正方形边长以准备采用的手机屏幕宽度为准。凹球面反射镜设置在眼睛对面，高度也基本等于正方形框架。半反射镜按正方形对角线设置，长边基本等同手机屏幕长度。眼睛位置尽量往凹球面反射镜靠，以获得尽可能短的光路。凹球面反射镜的曲率(c)以使图上从目镜发出的看屏幕边缘的入射视线(a)与反射出的出射视线(b)使(b)平行为准，余下的焦距问题可用目镜放大镜来配合、修正。

Claims (2)
