초록
We present a new binary data encryption and transmission technique based on 4-step phase-shifting interferometry for a security system. Phase-shifting interferometry is used for recording phase and amplitude information on CCD device. 4-step phase-shifting is implemented by moving the PZT mirror with equidistant phase steps of
