Recent advances in wavefront shaping, i.e., wavefront modulated by a spatial light modulator, have opened hopeful venues to focus light through scattering media in particular and unparalleled ways, by means of codifying the values of pixels of the modulator. The transmission matrix approach is one of the most exciting recent advances to obtain optimal phase distributions, due to the consent of enabling turbidity suppression, in both transmitted and reflected waves, with high resolution and large efficiency. However, the transmission matrix is ill-conditioned, which seriously affects the precision of phase distributions. In this paper, we study the ill-condition of the transmission matrix in detail. An idea of optimizing the singular values of the transmission matrix is proposed, which improves the accuracy and stability of the phase distribution. Experiments verify this idea.

基于波前整形的散射介质聚焦光时病态传输矩阵的详细研究

波前整形方面的最新进展，即由空间光调制器调制的波前，通过编码调制器的像素值，开辟了通过散射介质聚焦光的有希望的场所，尤其是无与伦比的方式。传输矩阵方法是获得最佳相位分布的最令人兴奋的最新进展之一，因为同意在传输波和反射波中以高分辨率和高效率实现浊度抑制。然而，传输矩阵是病态的，严重影响了相位分布的精度。在本文中，我们详细研究了传输矩阵的病态。提出了优化传输矩阵奇异值的思路，提高了相位分布的精度和稳定性。
