Abstract

PURPOSE:To detect blood at high sensitivity by making the incident intensities of light of two kinds of wavelength regions to a measuring cell at a fixed ratio, for example, equal, modulating the same with mutually different frequencies, discriminating the photometric values of the abovementioned two kinds of light having transmitted through the measuring cell depending upon the differences in the frequencies the comparing the same.
