摘要
激光光源在数字投影显示系统中的使用日趋广泛并成为未来发展的方向之一.衍射光学元件(DOE)用于激光数字投影系统,可利用其整形能力强、匀光性能好、体积小的特点实现空间光调制器件的高效率均匀照明,并有利于投影系统照明光路简化,提高系统集成度.基于傅里叶变换的分步迭代方法进行了该类DOE 元件的优化设计.DOE 采用16 台阶位相结构,设计结果实现了激光整形、匀光功能,其照明能量利用率达到85%以上,照度均匀性优于90%,与目标光强分布的均方根偏差小于7%.
Abstract
Laser light source is widely used in digital projection display system in recent years,and the laser display is representing one of the future development trend of display technology.In laser digital projection display system,diffractive optical element (DOE) can realize uniform illumination on light modulator utilizing its good beam shaping ability and small size.The advantages of adopting DOE are not only higher efficiency of light source,better uniformity of illumination but also making the display system more compact.DOE that has 16 phase level is designed by using the Fourier transform step-iterative algorithm and the function of beam shaping and uniform illumination is realized.The simulation results show that the energy efficiency of light source is better than 85% ,the uniformity of illumination is higher than 90%,and the Root-Mean-Square of difference of intensity profile compared with the ideal one is less than 7%.
