This paper reports the modulation transfer function (MTF) for aerial imaging optical system with aerial imaging by retro-reflection (AIRR) by use of two transparent spheres. MTF is measured under different positions of the spheres. Experimental results suggest that placing transparent spheres in specific positions can increase MTF.
