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 opt. ••There is still a need for novel methods to produce composite vortex beams.••We propose the method to produce a controlled superposition of such beams.••Phase patterns are divided between SLM cells in a random (or deterministic) way.••Full control of the mixed paterns proportion is possible.••Spatial Light ModulatorSuperpositionDigital holographyLaser beam shapingOptical vortexComposite optical vorticesThe Liquid Crystal on Silicon Spatial Light Modulators (SLMs) are used for wavefront geometry shaping. This results in a growing number of SLM applications, for instance: laser beam shaping, adaptive optics,,, image processing, optical trapping,,, dynamic holography and image projection,. Together with a wide range of applications, some serious drawbacks of the SLM are present, concerning their optical quality, stability, finite range of the phase modulation and relatively low speed. Fortunately, some of those can be corrected sufficiently for many applications,,,. Having well-corrected SLM it is possible to generate beams belonging to the well-known families such as Gaussian vortex beams,, Bessel beams, Airy beams. Vector bea. We divide the SLM's cells into two interlaced subsets so that the neighboring SLM cells are used for displaying various phase patterns. Both phase patterns are used for shaping the reflected beam. These two beams interfere at the image (camera) plane. The other way is a random cell splitting (Fig. 1). We have tested both methods and the differences between the recorded interference images are negligible. In the following sections, we will present such images obtained with a random splitting method, due to its higher flexibility. In the case of random pixels distribution, the number of pixels in subsequent parts does not have to be equal. We can easily change the ratio of cells assigned to the two-phase patterns. For example, one pattern may have 70% of the total number of cells while the secon.
