论文摘要
我们提出了一种新的方法，用于通过使用仅相位空间光调节器来产生轴向余弦结构光。我们使用全息技术实施了轴向余弦的结构光。计算机生成具有不同半径的双同心环缝，在缝隙上施加一个棱镜相，以倾斜光束，从而在缝隙上远离光轴。不同的环形束会产生带有不同轴向波向量的贝塞尔束，可以从两个贝塞尔束之间的干扰中获得轴向余弦的结构光。可以通过调整半径和双同心环形束的半径和初始相位差来调节轴向余弦的结构光的周期和相。我们从理论上和实验上验证该方法可以有效地产生轴向余弦结构光。
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.
