The SLM and the microlens array were mapped together by a 4f imaging system, 我看不懂4f imaging system的意思 This technique is well suited to the fabrication of a fixed periodic array of identical structures. However, the method suffers from a lack of flexibility and breaks down if an aperiodic array of distinct structures is required. Furthermore, the fabrication can often be very sensitive to any variation in focal intensity rendering a high degree of uniformity necessary in the beam profile of the laser. 这个整段都有一点一头雾水 这项技术相当适用於固定周期阵列,然而这个方法缺乏柔软度,也无法用於不同结 构的非周期性阵列,此外制作过程相当敏感,特别对於焦点强度的改变..... it was shown that a liquid-crystal spatial light modulator (SLM) may be coupled to a microlens array in order to address individual lenses simultaneously. We show in this Letter that such a configuration also holds significant potential for flexible parallel microfabrication. Individual foci can be effectively switched on or off for fabrication and steered from their natural focus, allowing for the fabrication of aperiodic structures. In addition, the intensity of individual spots can be adjusted and aberrations compensated,enabling a high degree of uniformity across the array 在这篇论文当中我们结合了microlens array及SLM,强调了弹性的平行结构有着强大的潜力 以及焦点能够有效率的被控制,此外各个焦点的强度都能被控制,使整个阵列都有一致性的 强度 自己翻的太烂了以致於有点看不懂 麻烦各位大大指点一下迷津 --
