摘要：

Logical moire uses the logical operators (AND, OR, XOR) to generate moire fringes from two 1-bit binary gratings within the computer. Phase shifting of these moire fringes is easily achieved by translating the computer-generated reference gratings in steps of one picture element (pixel). We analyze the phase-shift expressions based on three, four, and five shifted patterns by using logical moire patterns. Both simulated and real moire demonstrations are shown.
