Abstract
An optical system includes an illumination layer, an optical combiner, and an active optics block. The illumination layer includes an array of point light sources configured to emit calibration light. The optical combiner is configured to pass visible light to a front side of the optical system and to direct the calibration light to a camera that generates an image in response to the calibration light. The image includes an array of points corresponding to the array of point light sources. The active optics block includes an adjustable lens disposed between the illumination layer and the optical combiner and is configured to pass the calibration light to the optical combiner and to focus the visible light. The active optics block is further configured to adjust an optical power of the adjustable lens based on the image of the array of points.
