Abstract

<abstract abstract-type="main"> <title>Abstract</title> <p>In this paper, we disclosed the realization of a "continuous" nano‐structured alignment patterning for thin film Pancharatnam‐Berry phase (PBP) diffractive lens by the use of spatially linear polarized light converter technology. High optical quality thin liquid crystal polymer (LCP) film PBP lens with F number of 45.4 and a diffraction efficiency of 95.5%, operating in blue visible region has been demonstrated. The concave and convex polarization dependent property of the lens can be clearly observed by human eye, which is attractive in many display applications, for example, bifocal lens for eye glasses; camera zoom system; and polarization imaging.</p> </abstract>
