Paper Abstract

Calibration methods of photometric spectral selection channels of biomedical in vivo photometer-spectrum analyzer which allow to measure absolute value of light fluxes at luminescence wavelength band (0.66 - 0.9 μm) during probe by wavelength 0.66 μm are presented. Three experimental calibration schemes for photometric channel are designed. Each channel consists of narrowband light filter, high sensitive pin-photoreceiver, amplifier block and ADC. Advantages and shortcomings of every scheme are discussed. Measurements of complete flux of light back scattered by the investigated sample and spectral analysis of this irradiation allow analyzing experimental data at quantitative level. The investigations of optical characteristics of biological tissues in vivo were made by means of calibrated photometer-spectrum analyzer. Tissues of volunteers belonging to different age with various diseases were investigated.
