Anisotropy of retro-reflection influences the resolution of the aerial image formed with AIRR. We quantitatively evaluate imaging resolution for three types of retroreflectors using modulation transfer function (MTF) based on slanted knife edge method. The results show the measured MTF curves depend on the placed direction of the retro-reflectors.
