OPTICAL SYSTEM AND WEARABLE AUGMENTED REALITY DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240012250 titled 'OPTICAL SYSTEM AND WEARABLE AUGMENTED REALITY DISPLAY DEVICE

Simplified Explanation

The patent application describes an optical system and a wearable augmented reality display device. The optical system consists of an image projection assembly, a first optical assembly, a second optical assembly, and a stray light suppression member.

  • The image projection assembly emits image light.
  • The first optical assembly reflects and transmits the image light emitted by the image projection assembly.
  • The second optical assembly reflects the image light reflected from the first optical assembly and transmits light from a real scene.
  • The stray light suppression member is positioned between the image projection assembly and the first optical assembly, blocking light reflected from the first optical assembly to a central region above the reflection surface of the second optical assembly, and/or blocking light directly transmitted from the image projection assembly to two side regions above the reflection surface.

Potential applications of this technology:

  • Augmented reality devices for gaming, education, training, and entertainment.
  • Industrial applications for hands-free information display and guidance.
  • Medical applications for surgical assistance and visualization.

Problems solved by this technology:

  • Minimizes stray light and reflections, improving image quality and clarity.
  • Enhances the user experience by reducing distractions and unwanted visual artifacts.

Benefits of this technology:

  • Provides a more immersive and realistic augmented reality experience.
  • Enables users to interact with virtual objects seamlessly in the real world.
  • Improves safety and efficiency in various industries by providing real-time information and guidance.


Original Abstract Submitted

provided are an optical system and a wearable augmented reality display device. the optical system includes: an image projection assembly configured to emit image light; a first optical assembly configured to reflect and transmit the image light emitted by the image projection assembly; a second optical assembly configured to reflect the image light reflected from the first optical assembly and transmit light from a real scene; and a stray light suppression member disposed between the image projection assembly and the first optical assembly and adjacent to a position above an effective reflection surface of the second optical assembly, the stray light suppression member being configured to block light reflected from the first optical assembly to a central region above the reflection surface of the second optical assembly, and/or to block light directly transmitted from the image projection assembly to two side regions above the reflection surface.
