Abstract

See full text

An optical system for a head mounted display (HMD) includes a display layer, an illumination layer, an optical combiner, and an active optics block. The display layer is configured to emit display light and the illumination layer includes an array of point light sources configured to emit calibration light. The optical combiner is configured to pass the display light to a front side of the optical system and to direct the calibration light to a camera. The active optics block includes an adjustable lens disposed between the illumination layer and the optical combiner, where the adjustable lens is configured to pass the calibration light to the optical combiner and to focus the display light for a user of the HMD. The active optics block is further configured to adjust an optical power of the adjustable lens based on a calibration image captured by the camera responsive to the calibration light.
