摘要
The reflection property of the micro cutting cube corner prism film with ultra-high retro-reflection is analyzed theoretically by the method of geometrical optics, and verified by optical simulation software. The principle of the ultra-high retro-reflection property was illustrated and compared with the traditional micro cube corner prism film. Results indicate that, parallel light can be totally retro-reflected if perpendicularly striking the bottom of the micro cutting cube corner prism unit and ignoring optical absorption of materials, while the retro-reflectivity of the traditional micro cube corner prism unit is 66.7%. The simulation retro-reflectivity of this two type films are 92.3% and 62.4% respectively. The retro-reflection measuring method for film is established and the reflectivities of two type films above-mentioned are measured which are 67.8% and 39.5% respectively.
