Аннотация:The regularities of the transformation of the intensity profile of a collimated Gaussian wave beam formed by the control optical system at the exit of a long path are experimentally considered. A change in the symmetry of the beam cross-section when controlling its tilt and a change in shape and linear dimensions when controlling its area are considered. Based on the matrix model of the optical system, the limiting values of the targeting range of a two-lens system for a beam with a given diffraction length are established. The change scales the size of the output beam waist under rearrangement the characteristics of a two-lens optical system are discussed.
