摘要

贝塞尔光束对倾斜很敏感，限制了它在共聚焦扫描显微镜中的应用。我们讨论了一种利用空间光调制器(SLM)扫描贝塞尔光束而不需要机械运动的方法。在SLM输入中加入光栅相位，在整个成像平面上产生鲁棒的点扩展函数，其标准化保真度与单位的偏差小于1.5%。

Robust Bessel beam scanning without mechanical movement

Bessel beams are sensitive to tilt limiting its use in confocal scanning microscopy. We discuss a method for scanning a Bessel beam using a spatial light modulator (SLM) without the need for mechanical movement. Adding a grating phase to the SLM input produces robust point spread functions across the imaging plane that deviate less than 1.5% away from unity in terms of its normalized fidelity.
