Light field imaging is an emerging technology.Recently,moiré imaging film has become an important component of light field imaging technique.It has gained immense popularity due to its outstanding three-dimensional and dynamic imaging characteristics.In this paper,the state-of-art progress in research and application of the thin moiré imaging film was reported.By combining the micro-lens and micro-pattern arrays,the several visual effects such as three-dimensional and motion effects could be realized based on the moiré phenomenon.The working principle of producing three-dimensional and kinetic effects was given,such as the magnified factor,the orientation angle,the field depth and the dynamic parameters of the moiré image.The fabrication method of the imprinting mold of the microlens array on a large format substrate was introduced.Furthermore,the micro/nano-imprinting technique with high alignment precision and the printing technique with a resolution of more than 8000 dpi was especially demonstrated.Last but not least,the opportunity and challenge of the moiré imaging magnifier were discussed,which provides insight for the future applications of moiré imaging film in fields such as security anti-counterfeiting and dynamic display.
