Optical instrument for viewing nearby object as mirror image located farther away

Abstract

To provide an optical instrument for viewing a nearby object as a mirror image located farther away.SOLUTION: An object (6) such as a book or a game console is placed under a housing (1), and a light source (5) illuminates the object (6). Through double reflection by a half-transparent half-reflective mirror (3) and a reflective mirror (4), a user can view an image of the object located farther away in front of the housing (1). Adjusting a support member (2) can change the height of the housing (1), and changing the distance between the reflective mirror (4) and the object (6) can adjust the distance between the eyes of the user and the image of the object (6). Through double reflection, the image appears to be located farther away from the user. This allows the eyes of the user to remain in a state of viewing a distant object even when the user is looking at a nearby object (6), thereby reducing eye strain and preventing myopia.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to optical instruments. Summary of the Invention [Problem to be solved by the invention]

[0002] The problem to be solved by the present invention is to relieve eye fatigue caused by looking at a nearby object for a long period of time and to prevent myopia. [Means for solving the problem]

[0003] An object (6), such as a book or a game console, is placed under the housing (1), and a light source (5) illuminates the object (6). Through double reflection by the semi-transparent semi-reflecting mirror (3) and the reflecting mirror (4), the user can see the image of the distant object in front of the housing (1). By adjusting the support (2), the height of the housing (1) can be changed, and by changing the distance between the reflector (4) and the object (6), the distance between the user's eyes and the image of the object (6) can be adjusted. [Effects of the Invention]

[0004] The double reflection makes the image appear to be farther away from the user, so that even when looking at a nearby object, the user's eyes are still focused on the distant object, reducing eye strain and preventing myopia. [Brief explanation of the drawings]

[0006] If the object (6) is 30 cm from the semi-transparent semi-reflecting mirror (3), and the semi-transparent semi-reflecting mirror (3) is tilted at a 45 degree angle and is 30 cm from the reflecting mirror (4), the reflecting mirror (4) will reflect the object 30 cm from the semi-transparent semi-reflecting mirror + 30 cm from the reflecting mirror = 60 cm in front of it. If the reflecting mirror (4) is a concave mirror with a radius of curvature of 1 m, then The image formed by a concave mirror is expressed by the following formula: 1 / u+1 / v =2 / R Distance between object and mirror: u Distance between the mirror and the image: v Radius of curvature of reflector: R u =0.6 R=1 v=3 The imaging distance is 3 m. In other words, the user can see the image of an object located 3.6 m in front of them. Also, because it undergoes two reflections, the user can see an upright image.

Claims

1. An optical instrument that allows you to see a nearby object as a mirror image at a distance. The housing is supported by a support, and the front and bottom of the housing are transparent. The semi-transparent semi-reflecting mirror is installed in a housing, with the top tilted toward the back. The reflector is mounted within the housing and is located behind the semi-transparent semi-reflector.

2. The optical device comprises: A light source is attached to the bottom of the semi-transparent semi-reflecting mirror.

3. The optical device comprises: The height of the housing can be adjusted using the support.
