CARD GENUINE JUDGING APPARATUS AND CARD GENUINE JUDGING SYSTEM

摘要

A light projecting system 22 for projecting laser measurement light Q1 toward a hologram provided on the surface of the card 1 and on which an image 4 'based on the grid pattern 3 is formed, A determination means 30 'for determining the authenticity of the card 1 based on the photoelectrons output from the light receiving portion 28, a Fourier transform lens 27 for forming a grid pattern image on the light receiving portion 38, And determines the authenticity of the card 1 based on the grid pattern based on the reflection diffraction light.
