  The composite optical beams being a result of superposition, are a promising
way to study the orbital angular momentum and its effects. Their wide range of
applications makes them attractive and easily available due to the growing
interest in the Spatial Light Modulators (SLM). In this paper, we present a
simple method for generating composite vortex patterns with high symmetry. Our
method is simple, flexible and gives perfectly aligned beams, insensitive to
mechanical vibrations. This method is based on the ability to split SLM cells
between phase patterns that are to be superposed. This approach allows control
of the intensity relation between those structures, enables their rotation and
is capable to superpose more than two such structures. In this paper, we
examine its ability to produce superposition of two optical vortices by
presenting both theoretical and experimental results.
