讨论了一种采用电控双折射液晶空间调制器(ECB-LCSLM)的可编程相息图。 LCSLM能够从0到2 π进行连续相位调制。 对于相息图的生成,相位分布通过迭代方法计算并记录在具有16个量化级的LCSLM上。 我们讨论的特点和结构的LCSLM的可编程相息图的实现,同时比较计算结果和光学重建。
A programmable kinoform using an electrically controlled birefringent liquid-crystal spatial modulator (ECB-LCSLM) is discussed. The LCSLM is capable of continuous phase modulation from 0 to 2-pi. For the kinoform generation, the phase distribution is calculated by iterative methods and recorded on the LCSLM with 16 quantizing levels. We discuss the characteristics and the structure of the LCSLM for the implementation of the programmable kinoform while comparing the computed results and optical reconstructions.
