Abstract

The invention provides an AR optical system and an AR display device, and the AR optical system comprises a depth-of-field separation structure corresponding to an image source, wherein the depth-of-field separation structure is used for converting light emitted by the image source into a plurality of light beams with different depths of field; a convergent lens which is positioned on an emergentlight path of the depth-of-field separation structure and is used for receiving and shaping a plurality of light beams with different depths of field; a first semi-transmitting and semi-reflecting mirror which is positioned on one side, far away from the depth-of-field separation structure, of the convergent lens, and is used for reflecting the shaped light beams with different depths of field towards a set direction; a concave mirror which has a preset transflective ratio and is located on one side of the reflection light emitting direction of the first semi-transparent and semi-reflective mirror, wherein the concave surface of the concave mirror faces the first semi-transparent and semi-reflective mirror, and the concave mirror is used for reflecting and converging multiple light beams with different depths of field and then emitting the light beams into a set observation position through the first semi-transparent and semi-reflective mirror. According to the invention, the light emitted by the image source is converted into the plurality of light beams with different depths of field, thereby generating images with different depths, and improving the user experience.

Description

technical field [0001] The present application relates to the field of augmented reality technology, and in particular, the present application relates to an AR optical system and an AR display device. Background technique [0002] AR (Augmented Reality, Augmented Reality) is also known as mixed reality. Its principle is to apply virtual information to the real world through computer technology. The real environment and virtual objects are superimposed on the same picture or space in real time. Currently, people can interact with the real world through wearable devices, such as AR glasses or AR helmets. [0003] When normal human eyes are viewing objects, the angle between the line of sight of the two eyes is proportional to the focus depth of the single eye. When this relationship is broken, the human eyes will feel uncomfortable, and even dizziness and nausea symptoms will appear. This phenomenon is called Vergence conflict. [0004] In traditional AR glasses or AR helme...
