Abstract
It became necessary for proposing a remote non–contact method to measure angular positions and movement of an objects using Laser Dynamic Goniometer (LDG) as compared with the usual Photo-electrical autocollimators with narrow range of about 1deg. This article present analysis, errors as well as experimental results of using Laser Dynamic Goniometer to measure wide range with accuracy of approximately 0.1 arcs and a possibility of measuring constant angles with accuracy of 0.005 …0.1 arcs in the range of possible angles of 15…30degrees.
