Tutorial for universities M. : High School, 1985 - 353 s: il. — BBK 22. 34, M 33, UDC 535. The presentation of the material is carried out within the framework of electromagnetic theory using the Fourier transform for both monochromatic and non-monochromatic and chaotic radiations .. Along with the traditional ones, the book highlights issues that have been especially significant in the last 15-20 years: Fourier optics, Fourier analysis of random signals, matrix methods in geometric optics, holography, lasers, nonlinear phenomena, etc. The book is the fourth volume of the General Physics course for universities and universities. Previous volumes Mechanics and Theory of Relativity, Molecular Physics, Electricity and Magnetism were published in 1976, 1981 and 1983, respectively.
