Optical Systems with Multi-Layer Holographic Combiners - A simplified explanation of the abstract
This abstract first appeared for US patent application 18349096 titled 'Optical Systems with Multi-Layer Holographic Combiners
Simplified Explanation
The patent application describes an electronic device with a display module and an optical system that directs light towards the user's eye.
- The device uses hologram structures to replicate and focus the light onto an eye box.
- An image sensor is included to generate image data based on a portion of the light.
- The optical system redirects some of the light to the sensor and some to the eye box.
- Control circuitry compensates for distortions in the light by adjusting the display module based on the image data.
Original Abstract Submitted
An electronic device may include a display module that generates image light and an optical system that redirects the light towards an eye box. The optical system may have first hologram structures that replicate the light over multiple output angles onto second hologram structures. The second hologram structures may focus the replicated light onto the eye box. If desired, the device may include an image sensor. The first and second hologram structures may include transmission and/or reflection holograms. The optical system may redirect a first portion of the light to the eye box and a second portion of the light to the sensor. The sensor may generate image data based on the second portion of the light. Control circuitry may compensate for distortions in the first portion of the light by performing feedback adjustments to the display module based on distortions in the image data.
