ABSTRACT:
A method and apparatus for illuminating a surface to provide a desired light intensity. The light intensity at discrete points along the illuminated surface is measured through a light transparent material, and opaque materials are applied to the transparent material to block out some of the light and thereby produce a light filter such that the desired intensity at each of the discrete points along the surface is obtained. An oscilliscope, or alternatively, a computer display to indicate light intensity are used.
