Abstract

See full text

A coherent light beam from a light source is scanned by a scanning member and is incident to a light receiving surface of a light diffusing element. The incident light beam is emitted as diffused light, passes through an illumination optical system, and forms a drawing spot on an illumination target surface. When a scan control unit controls scanning of the light beam, an illumination area is formed by the moving drawing spot on the illumination target surface.
