Examples
- Generally a microscope will come with an assortment of these phase plates having different absorptions .
一架显微镜一般都带了一套这样的具有不同的吸性的相板。 - In this thesis , we propose a new method to generate a focused hollow laser beam by using an azimuthally - distributed 2 - phase plate and a convergent thin lens
本文提出了采用2位相板法产生聚焦中空光束的新方法。 - Abstract : the far - field spot characteristics of laser converted by random phase plate are analyzed theoretically , including the shape , size , rotational symmetry and diffractive efficiency of the spots , as well as the distribution of subsidiary spot . by comparing the influence of phase element shape ( triangular , square and hexagonal ) on the characteristics , we found that the random phase plate with hexagonal array structure is more suitable for the beam smoothing in laser fusion
文摘:从理论上分析了激光经随机位相板变换后在远场的光斑特性(包括光斑的形状、大小、旋转对称性、衍射效率以及旁瓣分布) ，通过比较三种形状位相元(等边三角形、正方形和正六边形)的远场光斑特性，得知正六边形位相元结构的随机位相板更适合于激光聚变中的束匀化。 - When a collimated - well gaussian laser beam passes through a 27i - phase plate and then focused by a lens , a focused hollow beam ( fhb ) will be generated behind the lens , as a result of the completely ( r = 0 ) and partially ( r 0 ) destructive interference effects around the central region of the beam
当一束准直的高斯光束通过具有2位相分布的位相片和一个薄透镜时，这将导致在入射高斯光束中心的完全和部分相消干涉效应，于是在透镜后就会形成一束聚焦中空光束( fhb ) 。 - And the correction of a step wavefront produced by a step phase plate is accomplished successfully . 6 . according to the phase modulation characteristic of an lcslm , arbitrary complicated wavefronts were modeled . the result shows that lcslm can be use to test the wavefront sensors and controller if lcslm has wider dynamic range and perfect optical quality
六、通过利用液晶空间光调制器的位相调制特性，成功地模拟产生了任意畸变波前，指出若该器件有更大的位相调制动态范围和均匀性，将有可能成为校验波前传感设备和波前畸变控制系统性能的有力工具。
