Effect Research of Phase Thickness Compensation Factor on the Energy Reflectivity of Multi-layer Optical Anti-counterfeiting Composite Film

Abstract

In this paper, we have given the equation of energy reflectivity, and discussed the designing principle of reflective anti-counterfeiting film for the high reflecting film system made of metal chromium film and symmetric transparent composite film F-P, then using MATLAB programming to draw out the influence curve of the phase thickness compensation factor on the energy reflectivity for12-layer membrane system. Contrasting the curve analysis, we have studied the effect of phase thickness compensation factor on the energy reflectivity of multi-layer composite film.
