FIELD: medical engineering. SUBSTANCE: this apparatus incorporates light source and exciting circuit to generate optical waves in spectrum including at least two different wavelengths, transmitting and receiving light guides, photoelectric conversion unit that generates output electric signals which correspond to these wavelengths, and electric unit processing unit. EFFECT: disclosed apparatus allows higher accuracy of measuring content of bilirubin due to reduced influence of dissipation of optical waves in patient's tissues and saving electric energy due to exciting circuit and electric signal processing unit. 6 cl, 6 dwg
