Problems solved by technology

However, Moiré magnification is not a traditional lens magnification. If the microlens period Tr of the lens layer or the micropattern period Tb of the pattern layer are set differently, the displayed Moiré image will be distorted.
Therefore, the above-mentioned periodic theory cannot explain the variable-period Moiré image

Abstract

The invention discloses a 3D imaging film. The 3D imaging film comprises a microstructure layer and a pattern layer. The microstructure layer comprises at least one focusing unit, each focusing unit comprises a plurality of distributed microstructures, and the distance between every two adjacent microstructures is defined as Dr. The pattern layer comprises at least one image-text unit, each image-text unit comprises a plurality of micro image-texts which are distributed, and the distance between every two adjacent micro image-texts is defined as Db. The Dr and / or the Db can change, the focusing unit is matched with the image-text unit, and the microstructures carry out sampling from the micro image-texts to form images with variations. The arrangement of the microstructures and / or the micro image-texts can change, and the positions of the microstructures and the micro image-texts can be accurately reflected through the Dr and the Db, so that a preset image can be formed, and the imageis not distorted.

Description

technical field [0001] The invention relates to the technical field of optical films, in particular to a 3D imaging film. Background technique [0002] Various 3D imaging technologies have received more and more attention in the fields of information, display, medical treatment, military affairs, anti-counterfeiting, and decoration. The use of microlens technology to achieve three-dimensional imaging has great potential and prospects. With the development of microlens array manufacturing process and the popularization of high-resolution printing and image sensors, 3D imaging technology has attracted more and more attention, and various performances of 3D imaging, such as depth of field, viewing angle, etc., have also been greatly improved. improvement. [0003] The common 3D imaging technology is periodical moiré imaging, and its design principle is: the microlenses of the lens layer are set periodically, and its period is Tr; the micropatterns of the pattern layer are als...
