In this Letter, we report on the generation of high-quality Debye diffraction-limited volumetric multifocal arrays. The multifocal arrays with a uniformity of 0.99 over the entire focal region of a high numerical-aperture objective are volumetrically generated by using the vectorial Debye-based three-dimensional (3D) Fourier-transform method, through the accurate phase modulation on an Ewald cap. Thus, this method is capable of dynamic spherical aberration compensation. Applying this feature into 3D parallel aberration-free optical recording reveals a significant increase in the throughput by two orders of magnitude.
在本信函中,我们报告了高质量德拜衍射极限体积多焦点阵列的产生。通过在埃瓦尔德帽上进行精确的相位调制,利用基于矢量德拜的三维(3D)傅里叶变换方法,在高数值孔径物镜的整个焦区内均匀度为0.99的情况下,体积式地产生了多焦点阵列。因此,该方法能够进行动态球差补偿。将此特性应用于3D并行无像差光学记录,可使吞吐量显著提高两个数量级。
