METHOD OF REDUCING OPTICAL ARTIFACTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240012190 titled 'METHOD OF REDUCING OPTICAL ARTIFACTS

Simplified Explanation

The abstract describes a method for reducing optical artifacts using a combination of polarizing beam splitters (PBS), display panels, projector lenses, and circular polarizers. Here is a simplified explanation of the patent application:

• A light beam generated by an illumination source is injected into a polarizing beam splitter (PBS).
• A spatially defined portion of the light beam is reflected from a display panel.
• At an interface in the PBS, the spatially defined portion of the light beam is reflected towards a projector lens.
• At least a portion of the spatially defined portion of the light beam passes through a circular polarizer between the PBS and the projector lens.
• One or more elements of the projector lens reflect a return portion of the spatially defined portion of the light beam.
• The return portion of the light beam is attenuated at the circular polarizer.

Potential Applications:

• Projection systems: This method can be used in projection systems to reduce optical artifacts and improve image quality.
• Virtual reality (VR) and augmented reality (AR): By reducing optical artifacts, this method can enhance the visual experience in VR and AR applications.

Problems Solved:

• Optical artifacts: The method addresses issues such as glare, reflections, and unwanted light scattering, which can degrade image quality and cause visual disturbances.

Benefits:

• Improved image quality: By reducing optical artifacts, the method enhances the clarity and sharpness of projected images.
• Enhanced visual experience: In applications like VR and AR, the method provides a more immersive and realistic visual experience by minimizing distractions caused by optical artifacts.

Original Abstract Submitted

a method of reducing optical artifacts includes injecting a light beam generated by an illumination source into a polarizing beam splitter (pbs), reflecting a spatially defined portion of the light beam from a display panel, reflecting, at an interface in the pbs, the spatially defined portion of the light beam towards a projector lens, passing at least a portion of the spatially defined portion of the light beam through a circular polarizer disposed between the pbs and the projector lens, reflecting, by one or more elements of the projector lens, a return portion of the spatially defined portion of the light beam, and attenuating, at the circular polarizer, the return portion of the spatially defined portion of the light beam.
