ACTIVE DISPARITY SENSING OF HEAD MOUNTED DISPLAY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240184107 titled 'ACTIVE DISPARITY SENSING OF HEAD MOUNTED DISPLAY

Simplified Explanation

The near-eye optical assembly described in the patent application includes a display waveguide and an optical structure. The display waveguide receives display light and directs it to the user's eye. The optical structure consists of an input coupler, an optical path, and an output coupler. The input coupler receives a portion of the display light from the waveguide, the optical path directs this portion to the output coupler, which then provides the light to a disparity sense circuit.
