Work experience

The influence of multiple beam interference on properties of complex polarization systems and spatial light modulators was studied in theory and in practice. The creation of compound polarization systems with necessary properties was with special calculation methods for multilayer media and complex elements developing. The impact of properties of light on operation polarization elements and systems was estimated. The opportunity to improve methods of atmospheric test was analyzed using compound automatic systems. The properties of liquid crystals of nanocomposites were studied. The analysis of a beam with a complex structure was conducted in order to optical trapping. The analysis of optical superresolution was considered.
