Metamers
specimens differing in spectral
reflectance but having colors
that match in light of one
spectral
composition
when
viewed by one observer, but
may not match in light of
another spectral composition, or
when
viewed
by
another
observer
Reflectance
the ratio of reflected radiant flux
to incident radiant flux
Reflection
the process in which incident
light leaves a surface or medium
from the side on which it is
incident
Sample
a specimen from a lot of
material
selected
for
measurement
Scattering
the process by which light or
other electromagnetic radiant
flux is re-directed over a range
of angles
Source
a physically realizable light
whose
spectral
power
distribution
can
be
experimentally determined
