摘要
为了克服指向光源裸眼三维显示器光源结构复杂的问题,研究了一种侧面发光塑料光纤(POF)阵列背光源的设计和制作方法。通过分析侧面发光POF阵列和柱面微透镜阵列组成的定向成像光路,得到了侧面发光POF阵列的排布公式。实验制作了一种用于指向光源的侧面发光POF阵列,测量了指向光源的串扰度。结果表明,在设计的视区最佳距离530 mm处,横向-200~200 mm区域内的最低串扰度可达1%以下。最后分析了柱面透镜像差、POF阵列光纤错位和视区视角增大对POF阵列指向光源串扰度的影响。
Abstract
To address the problem of the complex light source structure of a directional backlight in naked eye 3D display, a design and fabrication method for a kind of side-glowing plastic optical fiber (POF) array backlight is researched. An arrangement formula of the side-glowing POF array is obtained by analyzing the directional imaging optical path composed of side-glowing POF array and cylindrical micro-lens array. A kind of side-glowing POF array for directional backlight is fabricated and the crosstalk from the directional backlight is measured. The results show that the minimum crosstalk in the transverse regions of -200 mm to 200 mm is less than 1% at the optimal distance of 530 mm in the designed viewing area. Finally, the effects of cylindrical lens aberration, POF array optical fiber dislocation, and increasement of viewing angle on crosstalk degree of POF array directional backlight are analyzed.
