    Abstract

    Based on the characteristics of the FRTH in recording and reconstruction, a multiple fractional Fourier transform hologram (M FRTH) and its application in anti counterfeiting were proposed. The FRTH of several objects (or different parts of one object) with different transform order in different positions were respectively recorded on one holographic plate with simple fractional Fourier transform system conveniently. The multiple fractional Fourier transform hologram was fabricated and its characteristics in anti counterfeiting were discussed.
