Influence of the method of measurement on the optical anisotropy factor OPTAF of pyrocarbon

Creators

Description

This study describes the development and installation of an automatic microscope photometer for the measurement of the optical anisotropy factor OPTAF on the pyrocarbon coatings of fuel particles. After a short representation of the physical basis of this procedure the new microscope photometer is introduced. First measurements for the adaptation of the new instrument of the so far used microscope photometer are discussed. By these measurements the influence of the instrument on the value of OPTAF in the case of some special ways of measuring are explained and the appearance of an apparent anisotropy is interpreted.
