Application 07/935,507
of illumination systems 87 and 87a. Each of the imaging
stations has a prescribed source means which houses one or
more light sources 103, and projects a highly-uniform, yet
highly diffuse illumination beam which, absent a showing to
the contrary, is considered to be a "Lambertian integrating
vessel." According to the IEEE Standard Dictionary of
Electrical and Electronic Terms, a lambertian surface has the4
same luminance regardless of the viewing angle. Appellants
have not demonstrated that Martino does not possess this
characteristic and is not a "Lambertian integrating vessel."
Martino states that a diffusing coating may be applied to the
reflective surface 100 of reflector 89 in the illumination
system 87 and 87a (column 4, lines 29 through 31). Appellants
disclose throughout the specification that the preferred
sources of illumination are either tungsten-halogen lamps or
arc lamps. Martino discloses (column 3, lines 21 through 26)
that the illumination lamps 103 should be either tungsten-
halogen or an arc source. The particularly chosen
