High-resolution aerial imaging without aberration has been realized by use of a lens and retro-reflection. The lens in our proposed aerial imaging by retro-reflection (AIRR) optical system reduces image blurring caused by diffraction, ray shift, and scattering from the retro-reflector. The modulation transfer function (MTF) of the proposed system with a 441 PPI light source display achieves 42% at the Nyquist frequency.
