INFLUENCE OF THE TURBULENCE OF ATMOSPHERE DURIG OPTIC MEASUREMENTS

Turbulent phenomena in the atmosphere, which lead to fluctuation of the intensity of the optical signal, are the cause for additional errors in optical and electronic goniometric devices. A quantitative evaluation of these errors is presented in this paper. Different goniometric devices are used in optical and electronic devices for targeting, chasing and control. These goniometric devices consist mainly of coordinate sensitive photo receiver and optical receiving system that converts the angular coordinates into linear. Regardless of the photo receiver type, the signal coming from the object through the use of the optical system is focused on no more than two elements of the photo receiver. The difference in the signals of the two elements is proportional to the angular coordinate, and the beginning of the report coincides with the direction of the optical axis.
