TWO-DIMENSIONAL OPTICAL SCANNING APPARATUS,TWO DIMENSIONAL LIGHT RECEIVING APPARATUS AND IMAGE DISPLAY APPARATUS USING THE SAME

摘要

A two-dimensional optical scanning apparatus has at least one light source unit disposed on a plane which is perpendicular to a rotating axis. The light source unit may be a linear light source unit provided along a radial direction around the rotating axis, or an areal light source unit provided in a shape of a sector around the rotating axis. The light source unit rotates around the rotating axis to scan a light beam two-dimensionally. The light source unit may be substituted for a light receiving unit in a two-dimensional light receiving apparatus.
