Abstract

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.
