    • An apparatus for generating an independent coherent beam array from a single light source, in which individual coherent beams are selectively activated. The independent coherent beam array generating apparatus, which ensures high-efficient independent coherent beams from a single light source, are implemented by using a phase grating and a spacial light modulator. The number of multiple beams to be used as a light source for high-density recording and reading can be adjusted by varying the design of the phase grating. Regardless of the number of light sources required in various applications, once the beam array generating apparatus is adopted to the applications, the desired function of the applications can be implemented at low cost.
    • 用于从单个光源产生独立相干光束阵列的装置,其中各个相干光束被选择性地激活。 通过使用相位光栅和空间光调制器来实现确保来自单个光源的高效独立相干光束的独立相干光束阵列发生装置。 可以通过改变相位光栅的设计来调整要用作用于高密度记录和读取的光源的多个光束的数量。 不管在各种应用中所需的光源数量如何,一旦将光束阵列发生装置应用于应用,就可以以低成本实现所需的应用功能。
