Method and device of 3D imaging of microstructure optical film

The invention discloses a method and a device of 3D imaging of a microstructure optical film. The method comprises the following steps that a 3D imaging micro-image-text file is manufactured; transferfilm making is carried out on the generated 3D imaging micro-image-text file; and the transfer film is transferred to one of surfaces of the microstructure optical film in a hot stamping mode. According to the method and the device of the 3D imaging of the microstructure optical film, the 3D imaging micro-image file is made into the transfer film in a holographic imaging mode, moreover, the transfer film is transferred to one of the surfaces of the microstructure optical film in the hot stamping mode, and finally a periodically amplified 3D image effect is formed through the micro lens on theother surface of the microstructure optical film, so that the 3D reproduction of a high-precision micro-image is realized, the complexity of the 3D micro-image forming is reduced, and the manufacturing cost is reduced. 本发明公开了
