Assurance of uniformity of measurements in biomedical optical measuring instrumentes

Abstract

In this article deals with assurance of uniformity of optical measurements used in biomedical measuring instruments. Computer refractometric analyzer «PLAZMONTEST» is designed to determine the composition and properties of substances-analytes through the registration the angle of minimum intensity of reflection in conditions of surface plasmon resonance in monochrome light in visible spectrum from the sensor substrate. Non-invasive computer photogammetry (portable) ФГНК(П)1-01 is designed to measure the concentration of the total hemoglobin in the blood vessels of the microcirculatory bloodstream of human biological tissues or other living organism. Computer four-channel photoplethysmograph (portable) ФПК(П)4 is designed for diagnostics and point registration changes absorbance region of interest of the body. Meter of optical power IT 1703S is designed to measure optical power in optical fibers, optical components of intelligent sensors and optical fiber transmission system. The features of the development of measurement procedures and metrological certification of biomedical measuring instruments, manufacturing measures and metrological certification of measures, the calculation of the calibration dependence are considered, and all of this is with account for the requirements of Normative Technical Documentation in the field of metrology in the field of optical measurements.
