Bondariev D. Biomedical photometer with ellipsoidal reflectors calibration method improvement

The dissertation is devoted to increasing the efficiency of biomedical photometry with ellipsoidal reflectors by developing an information system of reference measurements in reflected and transmitted light. The dependence between the total illuminance of photometric images during photometry with ellipsoidal reflectors of samples and working standards of different thicknesses and the optical coefficients obtained on a certified spectrophotometer was established, which made it possible to develop an analytical model functioning of biomedical photometry information system. The biomedical photometer with ellipsoidal reflectors calibration method has been improved by developing an information system of reference measurements. It allows for determining the biological tissues' optical coefficients of total transmittance and diffuse reflection. The practical results obtained in the study made it possible to develop an algorithm and software for determining the coefficients of total transmittance and diffuse reflection of biological tissue samples of different thicknesses using a photometer with ellipsoidal reflectors, which made it possible to automate photometric image parameters analysis.
