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. 這個整段都有一點一頭霧水 這項技術相當適用於固定週期陣列,然而這個方法缺乏柔軟度,也無法用於不同結 構的非週期性陣列,此外製作過程相當敏感,特別對於焦點強度的改變..... 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 在這篇論文當中我們結合了microlens array及SLM,強調了彈性的平行結構有著強大的潛力 以及焦點能夠有效率的被控制,此外各個焦點的強度都能被控制,使整個陣列都有一致性的 強度 自己翻的太爛了以致於有點看不懂 麻煩各位大大指點一下迷津 --
