On the basis of its wide experience and competence, PAL has developed an innovative and efficient dynamic screen for classification of OSB strands,"QUADRADYN", which has been met with immediate success on the North American and European markets.

基于丰富广泛的经验和能力， PAL研发了一项针对OSB刨花集束的创新和高效的动态筛选系统，" QUADRADYN "，并且在北美和欧洲市场立即取得了成功。

This surface works a bit like a giant radio telescope dish in reverse: Rather than focusing parallel astronomical light rays to a point, it collects the scattered plasmons emerging from a tiny sample--positioned strategically near the mirror--and redirects them into a plasmon "beam" in the metallic plane.

这个表面的工作原理相当于一个倒置的巨型射电望远镜的盘面，不同于天文望远镜把平行的天体光线会聚到一点，这一设计起到的作用是收集从一个位置恰好位于像点的微小样品散射出来的等离激元，并把他们重定向成金属平面上的一个等离激元束。

In this paper,a technique to determine the geometrical properties of fractional Fourier transform of paraxial beams based on the phase space beam transformation matrix is presented.

The establishment and relaxation processes of the transient gratings, which are formed by two recording 514nm beams with different polarization directions, SS, PP, SP and ±45℃, are investigated. Using the weak absorption of the chromophores at 632. 8nm and the positive dichroism of the chromophores molecules, a kind of bi-photonic transient gratings, owing to the periodic distribution of Trans and Cis isomers, is established first time in azo-dye doped polymeric bulk sample.

实验考察了两束514nm的写入光在不同偏振情况下（SS，PP，SP和±45），在样品中形成的瞬态栅的建立和弛豫情况；利用偶氮生色团在632.8nm波段的微弱吸收和生色团分子的正二向色性，首次在块状偶氮聚合物材料中形成一种基于生色团反式和顺式异构体密度分布的双色光瞬态栅；利用瞬态栅的快速建立和弛豫，考察了其在衍射型全光开关方面的潜在应用。
