Diffractive optics analysis of integrated micro optical light guide plate

根据标量衍射理论,计算出集成微光学导光板的衍射光场分布解析表达式,结果表明,集成微光学导光板的亮度增强效果是传统方法的1.5倍,本结果对实验制作有理论指导意义.

In this paper, micro optical technique is used in light guide plate of backlight system. With the detailed analysis for ray transmitting of light guide plate, the analytic expression of diffractive light field distribution is deduced from the scalar diffraction theory. This analytic expression is integrated into the applications of small size display and its physical meaning is also discussed in detail. The results show that the brightness enhancement effect of integrated micro light guide plate is 1.5 times as the traditional methods. This paper can provide theoretical basis for practical fabrication.
