Abstract

See full text

The present disclosure is related generally to techniques for improving the performance and efficiency of display systems, such as laser scan beam display systems or other types of display systems (e.g., micro-displays) of an HMD system or other device. Display systems of the present disclosure may utilize polarization multiplexing that allow for improved optimization of diffraction optics. In at least some implementations, a display system may selectively polarize light dependent on wavelength (e.g., color) or field of view. An optical combiner may include polarization sensitive diffractive optical elements that are each optimized for a subset of colors or portions of an overall field of view, thereby providing improved correction optics for a display system.
