A METHOD FOR REDUNDANT MEASUREMENTS OF BRIGHTNESS
Abstract
The paper considers some theoretical problems, concerned with automatic correction of systematic errors, occurring in determination of real values of brightness under a nonlinear transfer function of a photoelectric transducer. A version of a solution for the problem of linearization of a general transfer function of digital brightness meters is given. The paper describes a procedure of a linearization, based on the functional-algorithmic methods, grounded on application of quantities substitution formulas. The redundant measurements equations are derived. It is shown, that it is necessary to generate correcting physical quantities, homogeneous with a measured physical quantity, associated with it by a certain dependence and providing realization of the proposed redundant measurements method.
