Abstract

本实用新型公开了一种电视机立体成像装置。 它为一种光学装置，置于电视机荧光屏前，可产生立 体图象感。本装置由上、下、左、右四个反射镜构成四 棱台状箱体，小箱口有反射透镜、大箱口有菲涅尔透 镜。各构件尺寸由特定关系式确定。
本装置还可抑制X射线辐射，具有结构简单、成 本低的特点。

Description

本实用新型涉及一种用于电视机立体成象的光学装置。
现有的电视机所显示的图象均不能产生立体效果。有人通过改变机内电路来实现图象的立体感，其结构复杂，效果不理想，不能实际使用。而立体电视，是发展的重要方向之一。本申请人曾研制出一种装置（已申请专利），能使电视机图象产生立体感，但结构和性能还不尽完善。
本实用新型的目的是，设计一种电视机立体成象装置，置于电视机荧光屏前而使荧光屏的出射交线产生合理位移，从而使图象产生立体效果。
本实用新型的技术解决方案是，它由上、下、左、右四个反射镜构成一个四棱台状箱体，该箱体的小箱口的宽△a和高△b与电视机荧光屏的宽和高相同，其设计特点是，所述小箱口置有反射透镜，大箱口有菲涅尔透镜，所述大箱口的宽△′a和高△′b以及小箱口平面到大箱口平面的距离△s分别由下列关系式确定：
△′a＝［1＋（ (△b)/(△a) －β）］·△a
△′b＝［1＋（ (△a)/(△b) －β）］·△b
△s＝K·△o
式中，△o为电视机荧光屏对角线尺寸，β为黄色分割法常数
（β＝

），K为常数（0.1≤K≤0.2）。
下面结合附图做出进一步说明。
附图说明：图1是本装置的结构图，图2和图3分别是图1结构的A－A剖视和B－B剖视结构。在图中：
1——菲涅尔透镜    2——上反射镜
3——反射透镜    4——右反射镜
5——下反射镜    6——左反射镜
由附图可知，本实用新型由上反射镜（2）、右反射镜（4）、下反射镜（5）、左反射镜（6）构成一个四棱台状箱体，小箱口（即四棱台的小底）的宽△a与高△b同所配用的电视机荧光屏的宽与高有相同的尺寸。本装置的技术特点是，所述小箱口有反射透镜（3），大箱口有菲涅尔透镜（1）。所述大箱口（即四棱台的大底）的宽△′a和高△′b以及小箱口平面与大箱口平面的距离（又称参照距）△s分别由下列关系式确定：
△′a＝［1＋（ (△b)/(△a) －β）］·△a
△′b＝［1＋（ (△a)/(△b) －β）］·△b
△s＝K·△o
式中，△o为电视机荧光屏对角线尺寸，β为黄色分割法常数
（β＝

），K为常数（0.1≤K≤0.2）。
本装置的设计原理是，将上述结构的装置的反射透镜置于电视机荧光屏前，所述反射透镜（3）可使荧光屏光线透射，其透射光的一部分直接经菲涅尔透镜（1）出射，另一部分到达四个反射镜（2）（4）（5）（6）由其反射到菲涅尔透镜（1）或至反射透镜（3）上，到达所述透镜（1）的光线由其透射出来，而到达反射透镜（3）的光线由其反射后再经透镜（1）出射。这样，就使荧光屏产生的光线落在不同的视区而产生相对位移。根据光线位移后能使人的视觉器官产生立体感的原理（如立体电影的成象原理），使人们在观看时对图象产生十分逼真的立体感，所述合理的位移量是由古典黄金分割法——这一符合人们视觉习惯的比例法则得出的。在设置了反射透镜和菲涅尔透镜后，其效果更加显著。
本装置可加做外壳而放在已有电视机荧光屏前，也可将传统电视机壳加长而使其同电视机做成一个整体。
本装置能有效地使荧光屏出射光部分产生合理位移，因而使人们对图象产生逼真立体感，适于各种规格与型号的黑白、彩色电视机。还能抑制X射线的辐射。结构简单、成本低。
实施例：按附图结构的本装置，菲涅尔透镜（1）焦距为75mm（可在50至100mm范围），取K＝0.152，其余尺寸按前述公式确定。
