Abstract :
In the report the theory of "calibration-free" measurements of optical characteristics of an atmosphere, water, solutions, transparent for light optical devices is considered. This theory is based on the use of cumulative measurements allowing one to exclude an influence of instrumental constants of various system blocks thanks to a choice of appropriate measurement geometry. The concrete examples of realization of the proposed theory are given. "Calibration-free" basis-nephelometric meters of turbidity (transparency) of fluids, tester of glass plate\´s optical thickness are considered. The results of experimental examinations confirming steadiness of the proposed systems to various noises in optical and electronic path are presented
