Waveguide methods for determining the magnetic properties of magnetic liquids are proposed. The methods are based on the use of the results of measurements of the position and value of the extrema of the experimental dependence of the reflection coefficient of a wave from a layer of the material.

We examine a method for measuring small movements of an object, based on calculation of the displacement of the image obtained using an optical interferometer. We estimate the effect of phase noise in reconstruction of the coherent structure of the field on the accuracy in measuring the movements. We have made practical estimates of the displacements of the real object from phase image data. We co...... hiện toàn bộ
