实验参数对光通过不透明介质的最佳透射率的影响

Effect of experimental parameters on optimal transmission of light through opaque media

Benjamin R. Anderson, Ray Gunawidjaja, Hergen Eilers

摘要:

空间光调制器(SLM)控制光通过不透明介质的传输是一种较新的实验方法,在各个领域有着广泛的应用。虽然有一个激增的研究技术,有很少的工作报告,考虑到各种实验参数对优化效率的影响。在这项研究中,我们探讨了各种实验条件对优化的影响,并发现强度增强取决于调制通道的数量,相位阶跃的数量,反馈积分半径,光束光斑的大小,和活动SLM面积。我们还开发了一个模型,基于高斯光束的传播与随机相位前,占大多数的测量效果。

英文摘要:

Spatial light modulator (SLM) controlled transmission of light through opaque media is a relatively new experimental method with wide applications in various fields. While there has been a surge in research into the technique, there has been little work reported considering the effects of various experimental parameters on the efficiency of optimization. In this study, we explore the effects of various experimental conditions on optimization and find that the intensity enhancement depends on the number of modulated channels, number of phase steps, feedback integration radius, beam spot size, and active SLM area. We also develop a model, based on the propagation of a Gaussian beam with a random phase front, to account for most of the measured effects.
