Abstract

PURPOSE:Light penetrating through the standard specimen and sample is converted into electric signal and the ratio of such electric signal is converted into the ratio of penetration to obtain digital indication and at the disposal of signal, by integrating action, SN rato is improved and even a minute difference in rate of penetration is clearly indicated.
