Aerospace Instrument-Making Annotation << Back Method of generalized selective modulation in atmospheric spectroscopy analysis and synthesis of sun photometers H.H. Asadov, D.Z. Aliyev, N.A. Abdullayev, R.N. Abdulov, E.F. Dadashov In the article the method of generalized selective modulation of optical parameters, allowing to compensate infralow frequency fluctuations of aerosol optical thickness is suggested. It is shown, that the suggested method allows to synthesize various variants of multiwavelengths photometers. On the basis of suggested method the synthesis of three wavelength photometer with two-parametric correction is carried out. Key words: Spectroscopy, sun photometers, aerosol; synthesis.
