Firstly, the formation of the retroreflected light field of the retroreflector is analyzed. The retroreflected light, the scattered light and the diffracted light which constitute the retroreflected light field are respectively explained. The effects of design deviation and incident angle of light on the energy distribution of retroreflected light The simulation of retroreflected light field has been done through the establishment of mathematical model, and the distribution of retroreflected light field under different working distance and point light incidence has been analyzed in detail.And two types of retroreflection Photometric measurement device for mirror reflective performance: long-distance reflective performance tester and a small retroreflective testing instrument developed by ourselves based on the energy distribution of the retroreflected light field when a point light source is incident.
