Helical structures exhibit novel optical and mechanical properties and are commonly used in different fields such as metamaterials and microfluidics. A few methods exist for fabricating helical microstructures, but none of them has the throughput or flexibility required for patterning a large surface area with tunable pitch. In this paper, we report a method for fabricating helical structures with adjustable forms over large areas based on multiphoton polymerization(MPP) using single-exposure, three dimensionally structured, self-accelerating, axially tunable light fields. The light fields are generated as a superposition of high-order Bessel modes and have a closed-form expression relating the design of the phase mask to the rotation rate of the beam. The method is used to fabricate helices with different pitches and handedness in the material SU-8. Compared to point-by-point scanning, the method reported here can be used to reduce fabrication time by two orders of magnitude, paving the way for adopting MPP in many industrial applications.

时段排列保留了信号的频谱特征,因而可以在与传输原始信号相同的信道下传输已排列的信号。这个特点使得时间分段话音保密系统在战术使用条件下很有吸引力。本文对所谓跳变窗口与滑动窗口的话音保密系统提出排列处理的数学分析。虽然测... 详细信息

时段排列保留了信号的频谱特征,因而可以在与传输原始信号相同的信道下传输已排列的信号。这个特点使得时间分段话音保密系统在战术使用条件下很有吸引力。本文对所谓跳变窗口与滑动窗口的话音保密系统提出排列处理的数学分析。虽然测量战术级的绝对保密性是不可能的,但本文分析了两种处理方式的相对保密性。
