СПОСОБ ИЗМЕРЕНИЯ СТЕПЕНИ ПОЛЯРИЗАЦИИ

摘要

FIELD: the invention refers to modes of measuring the parameters of electromagnetic radiation. ^ SUBSTANCE: the mode is executed in the following manner: electro-magnetic radiation is polarized by way of transmitting through two immobile polarizers the polarization axles of which are oriented every other 45 degrees relatively to each other. Two beams of polarized radiation fall on the two-area photoreceiver where the radiation in its turn is transformed in electric signals which are reinforced by the preliminary intensifiers and served on the schemes of selection and storing. Sequential serving of an analogue signal on the analogue-digital transformer is executed with the aid of an analogue commutator. The digital code of the analogue signals is served with an analogue-digital transformer on a microprocessor system where transformation of signals is executed according to an algorithm corresponding to above described mathematical model. Using of a polarized-sensible two-area photoreceiver leads to reducing noises at the expense of reducing the number of used sensible areas. ^ EFFECT: the invention increases the accuracy and quick-acting measuring of the extent of the polarization of radiation. ^ 2 dwg
