摘要

This paper proposes a simple method for predicting the line‑spread of an aerial imaging optical system using the aerial imaging by retro-reflection (AIRR) technique. The approach involves fitting test chart data in red, green, and blue, using two retro-reflector sizes, to construct an optical model. Analysis reveals that diffraction effects intensify with decreasing retro-reflector size and increasing wavelength. This technique enables estimation of optical spread characteristics without reliance on large-scale simulations of array-based systems.
