Abstract

The present paper examines the possibility of improving of the resolution of the phase rheological media without losing the unaltered diffraction efficiency by applying of surface- active substances. It is demonstrated that the concentration of the surface-active substances determines the value of the resolution capacity due to the reduction of the coefficient of surface tension of the phase rheological media. The infliction of the surface-active substances in a hyperfine layer on the free surface of the rheological media gives us an opportunity to record the optical information by means of holographic method on the transmitting surface of the multilayer structure. Such a multilayer structure gives us an opportunity to manufacture optical hybrids in the form of arrangements of photothermoplastic lenses with the period of 4-100micrometers and with the transmitting surface in the form of grating with the period of 0.2-1micrometers . It is determined that in case of such multilayer structures the question of proportionality of diffraction efficiency and dimensions of deformation (depth) needs further specification. The thing is that even when deformation is not substantial, the diffraction efficiency may be considerably increased due to the increase of density of deformation. In the process of research a technical plant is elaborated in order to select the mode of recording on the multilayer structures. This technical plant gives us the opportunity to obtain the permanent density of deformation and trace the changes in the relief deformation depth.
