摘要
提出了基于纯相位调制的传输矩阵通用测量方法,搭建了传输矩阵测量的实验装置。分别利用单位矩阵调制和哈达玛矩阵调制方式进行了传输矩阵测量,并实现了穿透散射介质的光波聚焦。实验结果表明,基于单位矩阵测得的传输矩阵,其聚焦点光强为背景光强的19倍;而基于哈达玛矩阵测得的传输矩阵,其聚焦点光强为背景光强的16倍。
The general measurement method of transmission matrices based on phase-only modulation is proposed and the experimental setup is established for the measurement of the transmission matrices.The identity matrix modulation and the Hadamard matrix modulation are employed respectively in the measurement of the transmission matrices,and the focusing of light waves through scattering media is realized.The experimental results show that the focusing point intensity of the transmission matrix measured based on the identity matrix is 19 times the background light intensity,while the focusing point intensity of the transmission matrix measured based on the Hadamard matrix is 16 times the background light intensity.
