使用相位调制的轴向余弦结构照明

Axial cosinoidal structured illumination using phase modulation

Xianlin Song, Jianshuang Wei, Lingfang Song

摘要:

提出了一种利用纯相位空间光调制器产生轴向余弦结构光的新方法。利用全息技术实现了轴向余弦结构光。计算机产生两个不同半径的同心环形狭缝,在狭缝上施加棱镜相位,使入射到狭缝上的光束偏离光轴。不同的环形光束产生不同轴向波矢的贝塞尔光束,两束贝塞尔光束干涉可以得到轴向余弦结构光。通过调节双同心圆环光束的半径和初始相位差,可以调节轴向余弦结构光的周期和相位。从理论和实验上验证了该方法可以有效地产生轴向余弦结构光。

英文摘要:

We propose a novel method for generating axial cosine structured light by using phase-only spatial light modulator. We implemented axial cosine structured light using holographic technique. The computer generates double concentric annular slits with different radius, a prism phase is applied on the slits to tilts the beam that incidents on the slits away from the optical axis. Different annular beam produce Bessel beams with different axial wave vectors, axial cosine structured light can be obtained from the interference between two Bessel beams. The period and phase of axial cosine structured light can be adjusted by adjusting the radius and the initial phase difference of the double concentric annular beams. We theoretically and experimentally verify that the method can effectively generate axial cosine structured light.
