Spatially multiplexed lens for head mounted display

摘要

An optical combiner includes an off-axis spatially multiplexed lens optically coupled to receive image light and direct the image light in an eye-ward direction. The off-axis spatially multiplexed lens includes a first sub-lens multiplexed with a second sub-lens. The first sub-lens and the sub-lens are configured to direct the image light to designated eyeward-regions.

主权项

1. A Head Mounted Display (“HMD”) comprising:
a display module to generate image light; and an optical combiner for combining the image light with external scene light, wherein the optical combiner includes an off-axis spatially multiplexed lens (“OASML”) optically coupled to receive the image light and direct the image light in an eye-ward direction, the OASML being a transmissive or reflective lens, the OASML including:
a first sub-lens having a first off-axis and having a first optical characteristic for light transmission or reflection, the first sub-lens being optically coupled to receive the image light and direct at least a first portion of the image light to a first eyeward-region; anda second sub-lens spatially multiplexed with the first sub-lens and optically coupled to receive the image light and direct at least a second portion of the image light to a second eyeward-region different from the first eyeward-region, wherein the second sub-lens has a second off-axis different from the first off-axis and having a second optical characteristic for light transmission or reflection different from the first optical characteristic.
