Description

一种微通道矩阵光波导平板及其制备方法
技术领域
本发明涉及无介质空中成像技术领域,具体涉及一种微通道矩阵光波导平板及其制备方法。
背景技术
无介质空中成像技术主要采用微通道矩阵光波导平板,是通过光路经过正交排列的两层透明材料的两次反射,从而在空中重新汇聚实现的,能够反射点光源、线光源、面光源,在空中汇聚后仍然是点光源、线光源、面光源,这一特殊的光路反射效果使得空中成像技术走向了实际引用,但是,现在所采用的两层正交排列的透明材料实现的微通道矩阵光波导平板,空中成像的分辨率和清晰度不够,不仅影响用户体验,还对应用场景提出了更高的要求,导致无介质空中成像技术的商业推广和大规模应用受到了极大的制约。
无介质空中成像技术是通过光学微镜结构来复制光场,在三维空间重现一个三维立体的实像。光学微镜结构记录来自“物空间”实物光源射向光板的每一条光线的强度、角度、波长等信息,并在阵列另一侧“像空间”复制出与记录光线完全镜像的光线,这些复制光线通过再聚焦过程,在“像空间”对称位置处形成与“物空间”物体完全镜像的实像,而微通道矩阵光波导平板就是我们所说的光学微晶结构,而现有的微通道矩阵光波导平板的制备方法为先将玻璃板材切割成若干条状,再将条状玻璃板材平行粘接成一块透光层叠体,再将两块透光层叠体粘贴构成一整块光学成像元件,但是采用粘结剂粘结方式实现拼接,由于粘结剂与玻璃属于不同介质,当光路从一种介质斜射入另一种介质时,必然会引起传播方向的改变,形成折射现象,从而会影响光路的反射路径,进而影响空中成像效果。
发明内容
针对现有技术存在的上述问题,本申请提供了一种微通道矩阵光波导平板及其制备方法,通过磁性材料吸引代替粘结剂实现光学元件的紧密贴合,可降低粘结剂对光学元件反射光的影响,制备得到的微通道矩阵光波导平板具有成像清晰度高,制备工艺简单的特点。
