Abstract
A spherical integrator has beam input and output apertures. The output aperture is opened at a position to which incident beam does not directly strike. The integrator has a curved inner surface which is a uniform diffusion surface. A galvanometer scanner has a mirror capable of adjusting a reflection angle of the beam from a light source such that a luminous energy beam reflected by the mirror to the input aperture is quantitatively varied. Beam from the light source is reflected by the mirror of the scanner to the input aperture of the integrator which diffuses and integrates the incident beam and outputs it through the output aperture.
