Abstract
An optical scanning control device is provided. The optical scanning control device includes a scanning unit configured to scan light emitted from a laser and a screen on which the light scanned by the scanning unit forms an image. A plurality of micro lenses are arranged in an array on a surface of at least one of a light-entering side and a light-exiting side of the screen. The micro lenses are arranged in an array in such a way that the center-to-center distances are randomized in at least one of a first direction and a second direction orthogonal to the first direction.
