We propose an aerial imaging by retro-reflection (AIRR) optical system to form a high-resolution aerial image by placing a ball lens at a virtually conjugate position. The ball lens parallelizes the incident light on the retro-reflector. The modulation transfer function (MTF) of the proposed optical system is greatly improved.
