Abstract
Provided is an electronic device including an optical engine including a projection lens configured to project light of a virtual image, a waveguide including an input grating on which the light of the virtual image is incident, an actuator configured to adjust a position of the projection lens relative to an optical axis of the projection lens, a light sensor configured to detect light passing through the input grating, a memory configured to store one or more instructions, and a processor configured to execute the one or more instructions to obtain a degree of parallelism of the light detected by the light sensor, obtain, based on the degree of parallelism of the light, a position adjustment value of the projection lens to detect light, and control the actuator to adjust a distance between the projection lens and the waveguide based on the position adjustment value.
