In this paper, geometric-phase lenses, which can not only correct wavefront aberrations but also magnify an aerial image, have been proposed for use in an aerial display system composed of a retroreflector array, an orthogonal-circular polarization g

We propose two types of wavefront aberration correction in geometric-phase lenses (GPLs). First, in situations in which the incident light on a GPL has a wavefront aberration represented by the Zernike polynomial, the wavefront aberration is eliminat

An aerial display scheme consisting of an orthogonal circular polarization grating (OCPG), a waveplate, a retroreflector array (RRA), and a right-angle prism (RAP) was developed. Because of the OCPG’s functionality, retroreflected light from the RR
