Abstract
An electronic device may have an optical combiner, a spatial light modulator, and illumination optics. The modulator may produce image light for the combiner by modulating illumination light from the illumination optics. Adjustable optical components in the illumination optics may be controlled to adjust the illumination optics between first and second states. In the first state, the adjustable optical components may provide the illumination light to the modulator with a uniform intensity across the lateral area of the modulator. In the second state, the adjustable optical components may focus the illumination light within a subset of the lateral area. The subset of the lateral area may correspond with a bright object in the image light. The control circuitry may control the illumination optics to ensure that the bright object remains visible at an eye box even when the device is located in bright ambient lighting conditions.
