Abstract

The present invention relates to a method for manufacturing an optical device, the method comprising the steps of: providing first and second optical elements having a pair of opposite surfaces; forming a reflective part on the surface of the first optical element among the pair of opposite surfaces; and bringing the first and second optical elements into close contact with each other and fixing the same to each other to form an optical device.

Description

technical field [0001] The present invention relates to a method of manufacturing an optical device, and more specifically, to a method capable of efficiently manufacturing an optical device in which a small reflection portion is arranged inside an optical element. Background technique [0002] The so-called augmented reality (Augmented Reality) is a technology that superimposes a virtual screen (virtual world) on the real world seen by the user's naked eyes. Since a single image is presented by combining the virtual world with additional information in real time in the real world, the initial stage Also known as Mixed Reality. [0003] Such augmented reality has been studied starting from the development of a see-through HMD (Head Mounted Display), but it has a different meaning from virtual reality (Virtual Reality). Since virtual reality immerses users in a virtual environment, users cannot see the actual environment. On the contrary, in augmented reality, users can see ...
