摘要(Abstract):
涡旋光的研究与应用是当前光学领域的前沿和热点。本文介绍了一种方便实用的涡旋光制备方法。我们首先利用涡旋光与高斯光的干涉,产生了叉形光栅结构。然后采用喷墨打印技术,将此叉形光栅图案打印在激光打印胶片上。最后通过平面光束照射叉形光栅,利用胶片上黑色区域的光吸收效应,实现了光线通过光栅空隙处的衍射,从而成功制备了具有不同拓扑荷数的涡旋光。与传统方法相比,我们提出的涡旋光制备方法不需要复杂的光学设备或昂贵的材料,大大降低了实验的技术门槛和经济成本,使涡旋光的制备更加普及和可行。此外,这种技术的简易性和低成本特性,使其在光学实验教学和基础科学研究中具有广泛的应用前景,尤其适合于资源有限的实验环境。
