چکیده
|
Fabricating an electrically switchable cylindrical fresnel lens based on holographic polymer-dispersed liquid crystals (h-pdlc) using a michelson interferometer is reported. simplicity of the method and possibility of fabricating different focal length lenses in a single set up are among the advantages of the method. it is demonstrated that the fresnel structured zone plate acts as a cylindrical lens and focuses light in one dimension. its electro-optical switching properties are also studied and it is found that at an applied electric field of e=6 vrms/nm across the sample, focusing property of the sample eliminates with a response of about 1 ms in a reversible manner.
