本发明提供一种小型且可抑制对比率之下降，并且能够射出经放大之图像光之光电装置。;本发明之光电装置包括：光源，其发出包含不同角度成分之光；及第1光学元件，其系将复数个导光材料介隔半反射镜层接合而成；且第1光学元件包括：第1面，其系以与半反射镜层平行之方式形成；第2面，其系以与第1面平行之方式形成；入射面，其系以与第1面形成之角成为第1角度之方式形成；及射出面，其系以与第1面形成之角成为第2角度之方式形成于与入射面为相反侧之位置；且光源系以使包含不同角度成分之光入射至第1光学元件之入射面之方式配置，第1光学元件之第1角度、第2角度及复数个导光材料之折射率系设为如下角度及折射率，即，分别自入射面入射并导光之来自光源之光中之经第2面反射后入射至射出面之光经射出面反射。; and a first optical element in which a plurality of light guiding materials are bonded to each other via a half mirror layer. The first optical element includes a first surface which is formed to be parallel to the half mirror layer, a second surface which is formed to be parallel to the first surface, an incident surface which is formed so that an angle made by the first surface and the incident surface is a first angle, and an emitting surface which is formed so that an angle made by the first surface and the emitting surface is a second angle, at a position opposite to the incident surface. The light source is disposed so that the light having the various angle components is incident on the incident surface of the first optical element. The first angle and the second angle of the first optical element, and a refractive index of the plurality of light guiding materials are angles and a refractive index with which the light which is incident on the emitting surface after being reflected by the second surface, among each of the light beams from the light source which is incident from the incident surfaces and is guided thereto, is reflected by the emitting surface. |
