Abstract

The concept of frequency conversion amplitude modulation (FCAM) screening was proposed in this paper, and the generation and variation of Moiré Fringe in FCAM screening were studied in this paper. We found the original Tollennar Moiré formula was not suitable for FCAM, to the forecast and calculation of Moiré Fringe in FCAM screening, we should establish the new formula. This paper provided the new Moiré Fringe formula based on the curve fitting, it could accurately describe and forecast the rules of Moiré Fringe in FCAM screening; In the meanwhile, this paper revised the mathematical model of Moiré Fringe based on the Fourier optics in the frequency domain, The new model was suitable for the Moiré Fringe calculation of the same frequency and frequency conversion AM screening.
