Project summary

The main objectives of the project are: elaboration of principally new laboratory technology of production of GB-elements with the given axial (may be radial) gradient of birefringence and modernized laboratory technology of production of polymeric GRIN-elements with the given axial/radial refraction index; development and manufacturing of new installations for creation and investigation of GB-elements; determination of applications of principally new optical elements - GB-elements with the given axial/radial gradient of birefringence.
