“…Wang et al 13) used the curved lens array to converge the parallel reconstructed light to the center, thus increasing the common display area of the lens unit. Peng et al 14) used a curved micro-lens array to expand the collected 3D object space viewing angle, and combined it with a flexible reconstruction display method to improve the image reconstruction quality and viewing angle of the system. Xie et al 15) combined the concave lens array, convex lens array and two columns of the orthogonal polarizer array, and increased the imaging pitch through the secondary mapping of a convex lens, thus expanding the display angle.…”

The traditional integral imaging system has a small viewing angle, mainly due to the existence of interference pixels in the generated element image. At the same time, in the 3D reconstruction scene, the content that is not in the effective reconstruction area will also cause image crosstalk between adjacent viewpoints, which affects the display angle. In this paper, a viewing angle enlargement method based on effective reconstruction area is proposed to establish the correspondence between the point pixels in the element image and the micro-lens in the micro-lens array, and the pixel information in the pixel recombination area is derived and updated, and the effective reconstruction area is used for constraint, so as to enhance the effective use of the element image information. The experimental results show that the element image with pixel update has a larger viewing angle and clearer reconstruction content.

“…Microlens array (MLAs), as an important micro-optics component, has been widely used in optical communications, optical coupling [1,2], optical fluids [3], micro-optical sensors [1], lighting [1,4], imaging, and display [1,5,6]. Therefore, many fabrication techniques of MLAs have been proposed to satisfy various application requirements of different scenarios, which can be placed into several categories: chemical synthesis method [7,8], optofluidic method [9,10], surface tension effect assisted technology [11][12][13][14][15][16][17][18][19][20][21], graphic transfer technology [22][23][24][25][26][27][28][29], mechanical manufacturing technology [30][31][32][33], and photolithography assisted technology [34][35][36][37][38][39][40].…”

An optical film integrating microlens array (MLAs) and 3D micro-graphics is an important way to achieve the naked-eye 3D display effect. The 3D micro-graphics is traditionally generated by the micro-nano imprint technology based on precision engraving mold, which leads to high production cost and low production efficiency, and thus restricts the rapid response to production tasks and large-scale popularization and application. In this study, a process scheme for large-scale printing of 3D micro-graphics using UV offset printing based on presensitized (PS) plate was proposed, matching with the MLAs fabricated by micro-nano imprint process to achieve naked-eye 3D display effect. We used the laser confocal microscope to systematically measure and analyze the geometric and optical performance of the fabricated MLAs in terms of height, curvature radius, center distance, spacing, focal length, and numerical aperture, and evaluated the influence of the publishing resolution of the PS plate on the display effect of 3D micro-graphics. The printing quality and display effect of 3D micro-graphics were further improved by adjusting process parameters such as printing speed and printing pressure. The results of the current study demonstrate that the combined application of micro-nano imprint technology based on precision mold and UV offset printing technology based on PS plate can achieve an excellent naked-eye 3D display effect in 360° all angles, which is efficient, cost-saving, and highly flexible.
