首发时间:2017-11-14
摘要:微透镜阵列是集成成像3D显示系统的核心元件。本文提出一种结合光刻与喷墨打印制备用于集成成像3D显示的针孔/微透镜阵列的制备方法。首先利用光刻技术制备用于阻挡杂散光的小孔光栅,利用喷墨打印技术将低粘度高透过率的UV树脂按需打印于小孔光栅圆孔凹槽内实现具有高精度、高对齐度的针孔/微透镜阵列的制备,并研究其集成成像特性。结果表明采用本文方法制备的微透镜阵列具有良好的三维形貌,所制备的黑色圆孔凹槽阵列可以有效阻挡杂散光,提高显示清晰度,且大大提高微透镜的对齐度,改善形貌,从而提高其成像特性。相比单独微透镜阵列或针孔阵列,利用该组合微透镜阵列可以获得更好的重构图像质量。

Fabrication of Combined Pinholes/Micro-lens Array Based on Ink-jet Printing for Integral imaging 3D Display
Abstract:In this paper, a new method that combined photolithography and inkjet printing has been proposed for the fabrication of pinhole /micro-lens array, which was applied for Integrated Imaging (II). Black hole array was prepared by photolithography to reduce the influence of stray light on the II. UV resin with low viscosity and high transmittance was used by inkjet printing to produce micro-lens array with high precision and high degree of alignment. The results show that the fabricated combined pinhole /micro-lens array has a good morphology under 3D laser microscope. The presence of pinholes array reduces remarkably the light spots irrelevanted to the imaging during reconstruction of images.. The resconstructed image obtained using combined pinholes/microlens array shows better performance compared to those using pinhole arrays or micro-lens arrays within our studies.
