1. An optical control apparatus comprising:
a lens comprising a pair of plates capable of blocking a portion of a path of light emitted from a light source and provided with chipped portions of a half-moon shape, and configured to collect light passing through an opening formed by said pair of plates and illuminate the light onto an object; and
a processor configured to change a light shading range of the light and an illumination direction of the light onto the object by moving the pair of plates so as to change a position of the opening in a plane perpendicular to an optical axis of the light.
