It is proposed to use multidomain (MD) liquid-crystal (LC) structures in LC microlenses (LCMLs). The main drawback of nonsymmetric LCMLs with planar orientation is that they involve a prolonged transition process accompanied by the formation of a disclination. This paper proposes and implements a method of putting LCMLs into a working regime based on the application of an MD structure. As a result, the time to put them into the working regime was reduced by about an order of magnitude. It is demonstrated that MD structures can be used to form LC lenses based on a Fresnel phase plate without using a complex electrode configuration.
