The experimental setup for investigating the effects of scattering of bimodal radiation propagating in the atmosphere is described. The differential scheme realized as two optical branches, reference and operating ones, similar to interferometric measurements, is used as a basis of the concept of measurements. However, in contrast to the interferometry, the amplitudes of light waves but not the phases are compared. The measurements are accurate to not worse than 0.5% of the values of detected signals.
