Principles are established for the design of ''calibrationless'' optic
ophysical diagnostic systems to analyze scattering media by means of a
ggregate measurements based on the changing geometry of excitations of
the medium and a combination of instrument constants. These principle
s are used as a basis for the design of new measurement systems to be
employed in the optical diagnostics of scattering media. The computati
onal and measurement algorithms that are used satisfy the requirements
of metrological certification and automation of the measurement proce
ss to the fullest extent possible.
